STEM CELL part 29

Stem cell 1

 

In the 1960s, scientists who were studying rats discovered two regions of the brain that contained dividing cells that ultimately become nerve cells. Despite these reports, most scientists believed that the adult brain could not generate new nerve cells. It was not until the 1990s that scientists agreed that the adult brain does contain stem cells that are able to generate the brains’s three major cell types-astrocytes and oligodendrocytes, which are non-neuronal cells, and neurons, or nerve cells.
