What are the Advantages and Disadvantage of Stem cell?

Stem cells offer significant advantages, including their potential for regenerative medicine, as they can differentiate into various cell types to repair damaged tissues and organs. They also hold promise for treating diseases like Diabetes and Parkinson's. However, the use of stem cells raises ethical concerns, particularly with embryonic stem cells, as well as challenges related to immune rejection and the risk of tumor formation. Balancing these benefits and risks remains a critical focus in ongoing research.
