Figure 4From: Cerebrospinal fluid promotes survival and astroglial differentiation of adult human neural progenitor cells but inhibits proliferation and neuronal differentiationCell extension outgrowth in adult human NSCs. A, Length of cell extensions (μm) after 1, 3, 6, 24, 72 hours of differentiation in P4-8F or adult human CSF. B, Number of cell extensions at 1, 3, 6, 24, 72 hours of differentiation in P4-8F or human adult CSF. A and B, Values represent the mean ± S.E.M from at least three independent experiments. * indicates P < 0.05 compared to each corresponding value in CSF. C, Representative microphotographs showing cell morphology after 1, 3, 6, 24, 72 hours of differentiation in CSF. Scale bar = 50 μm.Back to article page
