Brain Res. Dev. Brain Res. 122, 97-109. Inhibition of mitogen-activated protein kinase kinase blocks proliferation of neural progenitor cells. 2000

Learish, R.D., Bruss, M.D., and Haak-Frendscho, M.

Notes: A primary cell line from rat subventricular zone which remains undifferentiated over time was developed as a model for MAPK activation. Cell were stimulated with 20 ng/ml bFGF and 20 ng/ml EGF (Promega) to activate MAPK. The MAPK pathway was inhibited with either U0126 (Promega) or  PD98059. Immunocytochemistry was performed with the Anti-ERK 1/2 pAb (1:100 dilution) to detect both active and inactive forms of MAPK proteins and with the Anti-ACTIVE™ MAPK pAb (1:100 dilution) to specifically detect the dually phosphorylated, active forms of MAPK. Cells were also immunostained with the neuron specific marker Anti-III-tubulin mAb (0.5 µg/ml). Cell proliferation was monitored with the CellTiter 96® AQueous One Solution Cell Proliferation Assay System. Apoptosis within the cell population was monitored using the DeadEnd™ Fluorometric TUNEL System. (2391)
