For this PBS article, I learned that there’s lots of controversy going with stem cells. Today researchers are still learning how the bodies use stem cells to regenerate tissue. Stem cells are unspecialized cells that can possibly renew themselves for a long period of time through cell division. There are different types of stem cells. One of those would be the adult stem cell. Adult stem cells are unspecialized and they exist in a very small numbers of cells in an adult organ or tissue. They can be rare based in researchers. The second one would be embryonic stem cells. Embryonic stem cells are taken from embryos. They were first isolated in mice 20 years ago.
Things I would like to know after reading this article:
1)Why do the doctors use embryonic stem cells to isolate mice?
2)What is a cell division?
3)Where do they get embryonic stem cells?
