A–B, Overexpression of the membrane-bound BMP antagonist BAMBI in CTR hGPCs (4 CTR lines, 3
repeats/each line) significantly decreased their efficiency of astrocytic transition. B, However, BAMBI knockdown in
SCZ hGPCs (4 SCZ lines, 3 repeats/each line) was not sufficient to restore astrocytic differentiation. C, Besides
BAMBI, the BMP antagonists follistatin (FST) and gremlin1 (GREM1) were also upregulated in SCZ hGPCs, relative to controls. Scale:
50 μm; ***p<0.001, 1-way ANOVA for B; **P<0.001 by 2-tailed t-test for C;
NS: not significant; mean ± SEM.
