Glial stem cell culture, light micrograph

Glial stem cell culture. Fluorescent light micrograph of glial stem cells producing the protein NG2 (red) as they mature. These stem cells can differentiate into several types of glial cells, such as oligodendrocytes and astrocytes. More mature astrocyte progenitors are green, and nuclei are blue. Glial cells provide nerve cells with support and nutrition, form myelin (protein that coats the axons of the nerve cells) and participate in signal transmission in the nervous system. In the human brain, there are about 10 glia for each nerve cell

Australopithecus afarensis, artwork

Australopithecus afarensis. Artwork of a female Australopithecus afarensis hominid with her child. This hominid lived between 3.9 and 2.9 million years ago. Fossil specimens have only be found in eastern Africa. It is thought that A. afarensis may have given rise to several lineages of early human. Compared to the modern human skull A. afarensis had a forward protruding (prognathic) face and held a smaller brain
