What is/are the challenges facing organ regeneration using stem cells?

Question

Quizplus · Accepted Answer

All of the choices present significant challenges in organ regeneration using stem cells. Organs are highly complex structures with many types of tissues, making it difficult to assemble them using regenerated tissues. Organs are also innervated, and it is challenging to reestablish the nerve connections in regenerated organs. Even when an organ is successfully engineered, getting it to function normally when transplanted is not guaranteed. Finally, there is still much to learn about the genes that regulate stem cells, which makes it difficult to control their behavior and differentiation during organ regeneration.
