Image: This #neurosphere (bottom left) was prepared from neural stem cells extracted from an embryonic rat midbrain. After allowing the cells to proliferate and expand for 7 days, they were imaged with confocal #microscopy. Cells differentiated to neurons are labeled red with an antibody to βIII-tubulin, whereas astrocytes are labeled green with an antibody to glial fibrillary acidic protein (GFAP), an intermediate filament specific to astrocytes. All nuclei are stained blue with bisbenzamide.
When cultured with growth factors in vitro, neural #stemcells can generate neurons (red), as well as the cells that support them— astrocytes (green) and #oligodendrocytes. In culture, neural stem cells group together in ball-like clusters, called neurospheres (bottom left). Neurospheres are of great therapeutic interest because they have the potential to regenerate and replace neurons lost in traumatic brain injury and neurodegenerative diseases, such as #Parkinsons disease, #Alzheimers disease, and multiple sclerosis
(#MS). #byu #neuroscience
