A second population, called bone marrow stromal cells was discovered a some years later. Stromal cells are a mixed cell population that generates bone, cartilage, fat, and fibrous connective tissue. Also in the 1960s, scientists who were studying rats discovered two regions of the brain that contained dividing cells, which become nerve cells.

Despite these reports, just about scientists believed that new nerve cells could not be generated in the adult brain. It was not until the 1990s that scientists agreed that the adult brain does contain stem cells that are able to generate the brains three major cell types astrocytes (star shaped neurological cell) and oligodendrocytes, which are non-neuronal ce...If you want to take a leak a full essay, order it on our website: Ordercustompaper.com
