Description
Nestin is a class VI intermediate filament protein that is abundantly expressed in stem cells and progenitor cells in the mammalian central nervous system (CNS) during development. Upon differentiation, nestin becomes down-regulated and is replaced by other intermediate filament proteins. Nestin expression is widely used as a marker for CNS stem cells in the developing nervous system. Its transient expression is a critical step in the neural differentiation pathway. Down-regulated nestin may be re-expressed in the adult organism under certain pathological conditions such as brain injury, ischemia, inflammation, and neoplastic transformation.
An antibody (named ST1) against mouse nestin was raised in rabbit.
Applications

Not tested for other applications.

BMP2 (bone morphogenetic protein 2)-induced neurogliogenic fate conversion of neural precursors.
- Nestin expression (red) in neuroepithelial cells cultured with (B) or without (A) BMP2 (80 ng/ml) for 2 days was examined.
- S100-β expression (green) was examined in neuroepithelial cells cultured with (D) or without (C) BMP2 (80 ng/ml) for 2 days.
- Hoechst staining of the same fields (Insets, blue).
BMP2 dramatically decreased the number of nestin (a marker for undifferentiated neural precursor cells)-positive cells (B) compared with that in untreated cultures (A). The number of cells expressing S100-β (an astrocytic cell marker) was increased after 2 days of BMP2 stimulation (C and D). Thus BMP2 appears to change the fate of neural precursors from neuronal to astrocytic cells.
