Figure 2From: Growth hormone pathways signaling for cell proliferation and survival in hippocampal neural precursors from postnatal miceGH treatment promotes the proliferation of SGZ neurospheres. A) Neurospheres growing in defined media were treated for 24 h with GH (500 ng/mL), pegvisomant (Peg, 20 μg/mL), or GH + pegvisomant. Control cells were treated with saline. Four hours before the end of the treatment period cells were given a BrdU pulse (10 μM). Neurospheres were then dissociated, cells were collected by centrifugation onto coated cover slips, and BrdU was detected by immunocytochemistry. Each bar represents the mean + SEM of 3 experiments in triplicate. * = p < 0.05 vs Control; ° = p <0.05 vs Control and GH. B) Representative images of results presented in A. Scale bar = 10 μm. C) Neurospheres growing in defined media without EGF and FGF2 were treated for 24 h with GH or saline, and BrdU incorporation was detected as indicated. Each bar represents the mean + SEM of 3 experiments in triplicate.Back to article page
