(A) Quantification of GEC network arborisation with TGFβ (10 ng/ml) or BMP7 (100 ng/ml) treatment and co-treatment, as assessed by cord number, total cord length, average cord length and branching points (n=3, standard deviation bars, 2-tailed Student’s t test). (B) CTGF mRNA level in podocytes in 2D (black bars) and 3D (white bars) by quantitative reverse transcriptase PCR analysis in response to TGFβ (10 ng/ml) and BMP7 (100 ng/ml) stimulation and co-stimulation (fold change compared to control, n=3, standard deviation bars, 2-tailed Student’s t test).
