Confocal micrograph of astrocytes and oligodendrocytes from neural stem cells Astrocytes (green) and oligodendrocytes (red) derived from rat neural stem cells in culture. Both these cells are types of...

Fluorescent micrograph of differentiating mouse embryonic stem (ES) cells. Embryonic stem cells are pluripotent, meaning that they have the ability to differentiate into any cell type depending on th...

Amyotrophic Lateral Sclerosis (ALS, also known as Lou Gehrig's Disease) motor neurons created from induced Pluripotent Stem (iPS) cells made from the skin cells of an 83-year-old ALS patient. iPS cell...

This fluorescent micrograph shows stem cells labeled with green fluorescent protein (GFP) located at the base of the colonic crypt in a section of mouse colon. The stem cells are surrounded by numerou...

Smoothened (Smo; green), a downstream effector of Hedgehog (Hh), is expressed in most cells of the wild-type Drosophila germarium including follicle stem cells, but is excluded from Boi- and Hh-expres...
