Do we even need eggs?

[摘要] Prevention of transplant rejection is a significant challenge for researchers and healthcare professionals alike. The current solution is the use of immunosuppressant drugs, however these can have severe side-effects. Therapeutic cloning could solve the problem by allowing doctors to grow cells and tissues that are perfectly matched to individual patients. However, many researchers now think therapeutic cloning is unrealistic given the scarcity of human eggs. For this reason the spotlight is now turning to the different strategies aimed at persuading the immune system to tolerate foreign tissue. These stategies include stem cell and drug therapies.
