->''"The technology was brand new and cutting edge, but there had been a special report on how the newest Victor had received new eyes grown from his own harvested DNA."''
-->-- ''Fanfic/TheVictorsProject''

So, you're missing some limb or organ and are worried about tissue rejection. Don't worry, the doctor can just grow you a new one in this vat here. Oh, and there's no ethical issues to worry about, it's not like [[WalkingTransplant this cloned part has a brain]], it's just an arm or leg or liver.

Depending on the setting, this may be more, or less expensive than (equally functional) ArtificialLimbs, but it is almost always more culturally acceptable.

Some scientists are working on this in RealLife due to the scarcity of transplantable organs and the problem of immune reactions to transplants. Chimeric organs that could be suitable for transplant have been grown in pigs and sheep while bladders and tracheas have been produced in labs.

WalkingTransplant is this trope [[ExaggeratedTrope taken to the extreme]], where an entire person is created solely for the purpose of harvesting their organs for another.

----
!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* The trope is implied to be in use in ''Anime/CowboyBebop'', as Jet is occasionally asked why he got a [[ArtificialLimbs prosthetic arm]] instead of a cloned arm.
* This is possible in the ''Franchise/GhostInTheShell'' universe (although natural organ transplants are still used, and some people opt for [[{{Cyborg}} cybernetic organs]]). A company in the first season of ''Anime/GhostInTheShellStandAloneComplex'' [[WalkingTransplant grows cloned organs in genetically engineered pigs]] for its clients as a combined insurance policy (since you can have the organs implanted in you if there's an accident) and investment (since you can opt to sell your unused cloned organs).
* In ''Manga/JoJosBizarreAdventureGoldenWind'', Giorno Giovanna's [[FightingSpirit Stand]] Gold Experience can do this in order to heal people by turning an inanimate object into said body part and inserting it in place.
* This appears to be possible in ''Anime/MobileSuitGundam00'', as it's stated that [[spoiler:Louise]] could have replaced her [[AnArmAndALeg lost arm]] if not for contact with ToxicPhlebotinum.
[[/folder]]

[[folder:Comic Books]]
* ''ComicBook/JudgeDredd'': Cloning technology has developed to the point where both cloning full people and body parts is possible. Judge Logan is able to get a new arm after losing it in the line of duty.
* ''ComicBook/LobsterRandom'': Lobster has an arm cloned for him after [[AnArmAndALeg cutting off his left arm]], which he reckons takes a decade off the average age of his entire body. [[spoiler:He chops it off after getting cuffed.]]
* This is taken to a bizarre extreme in ''ComicBook/{{Transmetropolitan}}'' -- human body part cloning is so commonplace that a fast-food chain called "Long Pig" [[ArtificialCannibalism serves it]], and you can even [[spoiler:grow your own vice-presidential candidate]].
[[/folder]]

[[folder:Fan Works]]
* In the backstory to ''Fanfic/BaitAndSwitchSTO'', now-Captain Kanril Eleya had to have her right kidney replaced with a replicated copy after a knife wound sustained fighting off a BoardingParty.
* In a [[AlternateUniverseFic AU]]/[[RealPersonFic RPF]] involving the Music/SpiceGirls, ''[[http://fav.me/dd7ow55 Case of the Missing Technology]]'', knowing her original organs were sold on the BlackMarket, [[spoiler:Music/MelanieC]] had them cloned to replace them, thanks to the help of a bio-medical 3D printer. The narrator explains such technology was developed by the military in order to help the soldiers with severe combat injuries, allowing them to recover with less pain and reduce time or probabilities of organ rejection.
* ''Fanfic/ACertainDrollHivemind'': Misaka-11111 mentions that many of the organs from the dead [[CloneArmy Sisters]] were donated to those who needed them. The [[HiveMind Network]] decided they don't have a problem with this; after all, ''they'' don't need the organs any more. They did, however, ask why Academy City couldn't just clone up individual organs for each recipient; they have the technology, it's far less morally dubious, and there would be no chance of rejection. They don't get an answer.
-->'''Misaka-11111:''' We are not sure why, if it was so cheap to produce a new Sister, Academy City does not grow organs for use in hospitals from and for the intended patient. It would mean that no one would need to die, and also negate the chance of rejection. We suspect, once more, that there was widespread fraud involved in our creation, and that the formally listed costs have no relationship to reality whatsoever.
* In ''Fanfic/RealityIsFluid'', Lieutenant Commander Reshek Gaarra has to have both his lungs replaced with replicated copies after injuries sustained in an EPS conduit explosion.
[[/folder]]

[[folder:Films -- Live-Action]]
* In ''Film/The6thDay'', the benefits of organ cloning are used as a plea to try to drive down the "[[TitleDrop Sixth Day]] Laws" that forbid the cloning of complete human beings. In reality, [[spoiler:the owner of the cloning corporation only wants to [[ImmortalitySeeker achieve immortality]] via [[BrainUploading uploading his memories]] into the brains of {{Expendable Clone}}s]].
* This is the business model for the company in ''Film/TheIsland2005'', cloning client's body parts into a mindless sack for organ donations. Unfortunately for their bottom line, they discovered that without proper stimulation these sacks inevitably die, so they just went with [[WalkingTransplant full clones]] and started lying to them and the public.
* ''Film/RepoTheGeneticOpera'': [=GeneCo=] makes artificial organs after an epidemic of organ failures, then has assassins repossess them when the patients miss too many payments.
[[/folder]]

[[folder:Literature]]
* The [[HealingVat regrow tanks]] in ''Literature/EarthGirl'' can restore legs, arms, 98% of a person's skin and significantly injured internal organs. As long as your brain did not get squashed, you'd probably survive just fine.
* This is mentioned in the ''Literature/HyperionCantos''. However, it is apparently too expensive for most people.
* In ''Literature/KnownSpace'', this technology eventually ends the practice of [[OrganTheft organlegging]].
* In ''Literature/LegendsOfDune'', the early Tleilaxu are known as suppliers of transplantable organs that they [[OrganicTechnology grow on trees]]. However, while this is true, it doesn't provide enough organs to meet demand during the Butlerian Jihad, so most of their products are [[OrganTheft a side of their slaving business]].
* In Creator/RobertAHeinlein's stories about the Howard Families in the far future, there are several mentions of cloned parts being grown, starting with synthetic blood in ''Literature/MethuselahsChildren'' and getting up to full body replacement by ''Literature/TimeEnoughForLove'' 2,000 years later.
* In ''Literature/OryxAndCrake'', "pigoons" are [[WalkingTransplant chimeric pigs with human organs]] (several human organs, in fact), based on one possible method of producing artificial organs.
* In ''Literature/ThePrideOfParahumans'', the bioprinting processes that were used to produce the parahumans can also make individual organs. [[spoiler:Argentum has the intestine and liver damaged by a harpoon to the torso replaced by bioprinting but opts for a [[ArtificialLimbs prosthetic hand]] that is quicker to retrain.]]
* In the ''Literature/{{Rihannsu}}'' novel ''Honor Blade'', Dr. [=McCoy=] is shown harvesting tissue from an injured Romulan to grow him some replacement organs, including a new heart.
* Mentioned to be possible but illegal in the ''Literature/TalesOfTheBountyHunters'' story "Of Possible Futures: The Tale of Zuckuss and 4-LOM". Zuckuss needs a new set of lungs, but because therapeutic cloning is illegal, they need a lot of money to get it done on the black market. [[spoiler:After they pull a HeelFaceTurn and help out the Rebels, the Rebels reveal they've worked out a way to trigger the regrowth of the damaged tissues that doesn't require cloning.]]
* This is fairly common in the ''Literature/VorkosiganSaga''. Miles gets a whole new set of internal organs after his chest is blown out by a needle grenade, and Aral has to take some time off, waiting for them to grow him a new heart, after his heart attack. In emergencies, the parts that get installed are often undersized and need to grow ''in situ'', but with advance warning, full-sized parts can be grown.
[[/folder]]

[[folder:Live-Action TV]]
* In ''Series/TheExpanse'', cloned limbs and organs are readily available to Inner Worlders with enough money, or a military health plan, but [[AsteroidMiners Belters]] are often forced to make do with [[ArtificialLimbs prosthetics]].
* In the ''Series/{{Firefly}}'' episode "[[Recap/FireflyE12TheMessage The Message]]", Mal and Zoe's war buddy Tracy has a job smuggling cloned organs. They're illegal because, according to Simon, the technology isn't ready or fully approved yet, so smuggling them requires [[WalkingTransplant implanting them in a host]], who doubles as an incubator.
* ''Series/TheMandalorian'': Doctor Pershing explains that this is the reason he got into cloning research; his mother died of heart failure, and if their planet had the ability to clone organs, it simply wouldn't have been an issue. Pershing's own research focuses more on LegoGenetics; the implication is that cloned replacement organs are common on more prosperous planets, but his own homeworld just didn't have that sort of infrastructure.
* ''Series/TheOuterLimits1995'': In "[[Recap/TheOuterLimits1995S7E7Replica Replica]]", the company [=TranGennix=] receives a $1 billion contract to produce cloned organs. The process is developed by the husband-and-wife team of Zach and Nora Griffiths, who own [=TranGennix=] with Peter Chandler.
* ''Franchise/StarTrek'': Series post-''[[Series/StarTrekTheOriginalSeries TOS]]'' occasionally mention this.
** Doctor Bashir mentions cloning organs in season 7 of ''Series/StarTrekDeepSpaceNine'', and also requests a sample from Odo (a [[VoluntaryShapeshifting shapeshifter]]) so that Starfleet Medical can investigate being able to replicate suitable organs before battles without having to worry about matching types too much.
** ''Series/StarTrekVoyager'' mentions that {{Matter Replicator}}s are capable of this in some cases.
*** {{Averted|Trope}} in "[[Recap/StarTrekVoyagerS1E4Phage Phage]]"; after [[TooDumbToLive his own stupidity]] leads him to walk into a Vidiian ambush and [[OrganTheft have his lungs stolen]], Neelix cannot have them replicated, as they are too complicated. This forces the Doctor to develop [[HardLight holographic lungs]] as a temporary measure until the crew can either track down his stolen organs or find a compatible donor.
*** In "[[Recap/StarTrekVoyagerS1E8Emanations Emanations]]", the EMH resurrects an alien brain cancer victim by removing the tumor from her brain stem, replicating replacement tissue, then following the standard post-mortem resuscitation procedure for her class of life-forms.
* ''Series/TheXFiles'': The episode "[[Recap/TheXFilesS01E16YoungAtHeart Young at Heart]]" has a scientist ''trying'' to do this to prisoners (and removing their limbs so that he can try to clone new ones) using salamander DNA mixed with human. You can probably guess how well this turns out.
[[/folder]]

[[folder:Tabletop Games]]
* In ''TabletopGame/BattleTech'', the highest echelons of the old Star League and the modern Clans have access to this level of tech, but it's [[LostTechnology LosTech]] elsewhere.
* In ''TabletopGame/EclipsePhase'', most parts can be regenerated after a few days in a HealingVat -- a severed head can get a new body in a week or two. There are also "Pods" that are {{Artificial Human}}s assembled from vat-cultured organs and cybernetics as a cheaper alternative to purely biological biomorphs.
* In ''TabletopGame/HcSvntDracones'', replacing limbs counts as General Surgery, as does adding tails or other non-prehensile appendages; a second pair of arms or legs requires Augmentation Surgery that costs twice as much. You can get an {{Artificial Limb|s}}, but it costs five times more than regeneration and has no special advantages aside from concealing weapons, being more of a fashion statement than anything.
* ''TabletopGame/{{Shadowrun}}'':
** It is possible for characters to receive replacement body parts or [[BioAugmentation bioware]] that are specifically clone-grown for them.
** There are also mass-produced "Type O" transplants produced from the cells of one Owen Whiting, who lacks the proteins that trigger immune reactions.
* In ''TabletopGame/TranshumanSpace'', cybernetics are considered obsolete; nearly everyone waits a couple weeks for a cloned body part instead of just printing off a prosthesis.
* ''TabletopGame/{{Traveller}}'':
** Regrown limbs and basic prosthetics cost the same and have practically the same statistics; the difference is thematic.
** On the Tech Level 16 world of Vincennes (''Megatraveller Journal'' #3, "Worldguide: Vincennes"), cloning of injured and damaged organs and limbs is commonplace.
[[/folder]]

[[folder:Video Games]]
* ''VideoGame/DeadSpace1'': Overlaps with WalkingTransplant. USG ''Ishimura'' has a whole section dedicated to replacing limbs since it's a mining vessel where injuries can happen very frequently. This facility contains tubes full of green liquid which have infants floating in them. It's never explained if they are conscious or not, and how the process works; however, since we never see any clones of a different age, it suggests that they are simply organ farms without higher mental functions.
* The ''VideoGame/{{Halo}}'' games have this in their lore, in a process called "Flash cloning". It can recreate organs, skin, and even blood in a short amount of time with the use of cells from the same area, preventing transplant rejection because the body will still recognize it as its "organ". The facilities used can be the size of a ''shoe box,'' and the process can even clone entire human beings, though they suffer from accelerated aging or medical problems as they get older and start to wear out due to the process not being designed to create such a large number of cells. This was used in an unusual way by Dr. Catherine Halsey, who cloned her own brain to use as the basis for Cortana.
* ''Videogame/{{Loopmancer}}'' revolves around a scientific breakthrough from Tompson Technologies, a bio-tech MegaCorp who managed to recreate perfect human limbs and organs from chimpanzees. [[spoiler:Until you found out the truth in a later stage - turns out the organs aren't cloned from apes, but from HumanResources, when you uncover Tompson's underground labs filled with imprisoned humans]].
* ''Franchise/MassEffect'':
** In ''VideoGame/MassEffect1'', Garrus asks Shepard for help tracking down a Salarian MadScientist who was cloning his patient's organs for the black market, [[WalkingTransplant growing them inside of individuals]] and not removing them if they failed to develop properly.
** In ''VideoGame/MassEffect2'', it's implied that during the [[WeCanRebuildHim Lazarus Project]], Shepard's skin and possibly eyes might have been replaced via cloning.
** In ''VideoGame/MassEffect3'', a background conversation at Heurta Memorial Hospital reveals that the soldier Shepard helped free from a trapped girder during the prologue, unfortunately, is going to have their limb amputated. However, the doctor assures them that if they're lucky, they could have a replacement cloned limb ready for grafting within the next six months.
* Coroner and mortician John Dresden in ''VideoGame/ShadowrunReturns'' claims that transplants harvested from dead bodies are becoming a dying business because grown transplants are just cheaper. Dresden still has business because the company he works for, Organ Grinders, also functions as a morgue.
[[/folder]]

[[folder:Webcomics]]
* ''Webcomic/TwentyFirstCenturyFox'': Both cloning and bionics are available, but the rehabilitation is longer with cloned limbs, which was why Tora Scobee went with bionics after his accident even though he hated himself for the decision later.
* In ''Webcomic/MyLifeAtWar'', one of the "Gunrat Girls" was sent back to Treadhaven to get a new arm from "the tanks" for two more years on her contract.
* ''Webcomic/QuentynQuinnSpaceRanger'': {{Matter Replicator}}s can be used to make replacement organs, at least one company gave employees full scans as part of their medical benefits. [[spoiler:One character uses that data to create a full clone of his dead wife.]]
* In ''Webcomic/SchlockMercenary'', [[ArtificialLimbs prosthetics]] are generally temporary and only issued when cloning tanks are unavailable or the HMO doesn't cover them. PlayedForLaughs with the [[https://www.schlockmercenary.com/2003-12-21 slogan]] of one popular body-part cloner:
-->''Hand Me Down will give you a hand in the time it takes our competitors to give you the finger.''
* In ''Webcomic/{{SSDD}}'', it is possible to clone biological body parts, but most CORE troops prefer to upgrade with [[ArtificialLimbs cybernetics]].
[[/folder]]

[[folder:Western Animation]]
* Medical technology in ''WesternAnimation/{{Futurama}}'' is so advanced that destroyed limbs can be recreated with ease:
** In [[Recap/FuturamaS3E15IDatedARobot "I Dated a Robot"]], Fry goes to "Handcrafters" to get new hands sewed on after losing the originals in a ''T. rex'' feeding accident.
** When Fry's [[TheNoseless nose gets stolen right off his face]] in [[Recap/FuturamaS4E17SpanishFry "Spanish Fry"]], Leela suggests letting the Professor clone him a new one, but Fry refuses, saying that "It wouldn't be the same, I don't wanna teach a new one how to shoot milk when I laugh."
** In [[Recap/FuturamaS7E2AFarewellToArms "A Farewell to Arms"]], Fry and Leela each have an arm ripped off and the Professor grows them new ones.
* ''WesternAnimation/SherlockHolmesInTheTwentySecondCentury'': In "The Engineer's Thumb", Moriarty's [[OrganTheft organ-legging]] turns out to be using cloned parts, which are illegal due to CloneDegeneration.
* In the ''WesternAnimation/StarTrekLowerDecks'' episode "[[Recap/StarTrekLowerDecksS4E08Caves Caves]]", a member of Delta Shift walks into a RapidAging field with a broken leg, which causes the leg to rapidly heal incorrectly before eventually becoming necrotic and falling off. Mariner decides that retrieving the leg isn't worth the trouble and simply takes him back to the ship so Dr. T'Ana can grow him a new one.
* ''WesternAnimation/TransformersPrime'': Starscream [[OrganTheft loses his Transformation Cog]] and struggles to find ways to compensate for his new handicap. After cloning himself to create loyal minions fails, he harvests the T-Cog of one of his dead clones as a replacement.
[[/folder]]

[[folder:Real Life]]
* TruthInTelevision, or at least it's becoming so. [[http://www.cbsnews.com/8301-18560_162-6698375.html Regenerative medicine]] [[http://en.wikipedia.org/wiki/Regenerative_medicine is a real science]] being researched by biotech companies and the Pentagon that can grow replacement organs using a person's cells. They've created beating hearts, ears and bladders, and are working on creating kidneys, livers, lungs and more. [[http://www.cbsnews.com/8301-3445_162-3960219.html This video]] demonstrates that they have medicine and materials that can trigger processes in the body to regrow severed fingers, and damaged skin, and [[http://www.wired.com/dangerroom/2011/11/regenerative-medicine-muscles/ muscle tissues]]. One of the benefits is reverse-engineering a person's ''skin cells'' to clone other organs, practically removing the chance of organ rejection.
* There's also the growing field of [[http://www.organovo.com/science-technology/bioprinting-process Bioprinting]]. 3D printers that lay out living cells.
* An alternative might be to [[http://www.telegraph.co.uk/science/science-news/8584443/Pigs-could-grow-human-organs-in-stem-cell-breakthrough.html grow human organs in animals]] such as pigs by injecting human stem cells into animal embryos.
* They've [[http://gizmodo.com/5749968/the-skin-gun-that-sprays-new-skin-on-burn-victims-is-real made a spray-on skin gun]] that regenerates skin (considered the body's largest organ) using a person's stem cells from their skin, and turning it into a gel or a spray. It already works, only takes 90 minutes to prepare, and only needs an hour to heal the skin, whereas skin grafting can take weeks. One reason it's not on the market yet is because they want to improve it to be able to regrow ''everything'', from hair to restoring the tissue of internal organs during operations.
