Figure 4

Secretion of fibronectin. Polarized hPTEC were stimulated with TGF-β from the basolateral and from the apical side for 24 to 72 h. Secreted CTGF and fibronectin were detected in the basolateral (b) or apical (a) compartment. The blot is representative of 3 experiments with different hPTEC isolations. In the experiment shown CTGF was below the detection limit in the basolateral compartment.
