Role of human growth factors in induction of rat neural markers in various culture settings; qRT-PCR. (A) Effect of FGF2 inhibition on rat nestin. Rat neural cells were stimulated with SB623 cell-derived conditioned medium (25%), which increased the nestin expression. The presence of FGF2-neutralizing antibody (bFM1), but not FGF2-specific nonneutralizing antibody (bMF2), concentration-dependently inhibited the nestin increase. (B) Effect of human FGF1 inhibition on rat nestin. Rat neural cells were stimulated by MSCs (60 or 200 cells/well), MSC-CM (5%), or recombinant FGF1, or FGF2 (both at 5 ng/ml), which led to the induction of rat nestin. The application of the anti-human FGF1 neutralizing antibody decreased nestin mRNA levels induced by all stimuli but the recombinant FGF2. (C) Effect of BMP inhibition on rat GFAP induction. Rat GFAP was induced by coculturing rat neural cells with SB623 (200 cells/well). A BMP inhibitor noggin concentration-dependently decreased the GFAP induction. (D) Effect of HGF silencing in MSC on rat CNP induction. Rat CNP expression was stimulated by coculturing rat neural cells with MSC transfected with either HGF siRNA (siHGF) or control siRNA (siControl). A lower CNP induction was observed in cocultures with siHGF-transfectants.
