Glial fibrillary acidic protein rodent brain. These isoforms include GFAP kappa, GFAP +1 and the currently best researched GFAP delta. GFAP delta appears to be linked with neural stem cells (NSCs) and may be involved in migration. GFAP+1 is an antibody which labels two isoforms. Although GFAP+1 positive astrocytes are supposedly not reactive astrocytes, they have a wide variety of morphologies including processes of up to 0.95mm (seen in the human brain). The expression of GFAP+1 positive astrocytes is linked with old age and the onset of AD pathology. Glial fibrillary acidic protein Glial fibrillary acidic protein (GFAP) is a protein that is encoded
Radial glial cell the lateral ventricles of the developing cortex, and the phasic migration of their nuclei depending on their location with the cell cycle (termed “interkinetic nuclear migration”). Radial glia are now recognized as key progenitor cells in the developing nervous system. During the late stages of neurogenesis, radial glial cells divide asymmetrically in the ventricular zone, generating a new radial glial cell, as well as a postmitotic neuron or an intermediate progenitor (IPC) daughter cell. Intermediate progenitor cells then divide symmetrically in the subventricular zone to generate neurons. Local environmental cues such as Notch and fibroblast growth factor (FGF) signaling, developmental
