1. What is the advantage of using a patient's stem cells to make organ to replace the patient's failed

organ?

This is because it prevents organ rejection during transplant. so far the new organs share the same stem cells with the patient ...; like cells, like tissues will not give rise to immune response which usually lead to rejection.

It also saves time, and ensures survival since there is no need to wait for a compatible donor, before the transplant can be possible.

Explanation:

Collecting a patient's stem cells and using them for their treatment is known referred to as autologous stem cell transplantation. In autologous stem cell transplantation, stem cells are harvested in the patient's bloodstream or the bone marrow and used to treat or grow organs for the patient.

Using stem cells harvested from your own body is advantageous over stem cells collected from a donor. This is because the case of incompatibility is eliminated. There is also less risk of rejection of organ or graft versus host disorder, where the donor cells attack the host cells thinking they are foreign bodies.

There are fewer side effects and quicker engraftment and therefore quicker recovery.
