It should be possible since in the laboratory they have managed to grow a human bladder in cell scaffolding using the patient's own cells, or some such like that. A few may have been transplanted. Though it may not be ready for general hospital use yet I would guess. So it seems, and once the genetic knowledge and technology is there it should be possible, though expensive at first, to get some dna samples of an animal and grow what they can make into a fur coat, leather ect without harming the animal, or even some meat, without harming any animals, by just growing some skin, skin & hair, meat, ect. Though the knowledge and technology may be decades or longer away.
