As everyone knows that the objective of stem cell research is to save people’s precious life. Once this research gets to success, injured neurons could no longer be a threat to human’s life. Because the embryonic stem cell research is controversial, scientists have developed other ways to extract the stem cells without killing the embryos. Undoubtedly, these ways are much more acceptable and should be supported substantially. However, these ways, including taking adult stem cells and reprogramming skin cells, either have not been approved yet or would not be safe enough. Considering this situation, I don’t think the expanded embryonic stem cell research should be suspended.
