Fig 3. Promotion of HGF-induced tubule formation in the presence of GDNF.

Fig 3

A: Morphology of RPTECs cultured in gels in the absence or presence of HGF (50 ng/ml) with GDNF (100 ng/ml) for 5 days (Magnification, ×100 and ×400). Arrowheads indicate the lumen of tubular structures. B: Quantitative analysis of tubule formation. RPTECs were cultured in gels with the indicated factors for 5 days. Values are the mean ± SE (n = 3). *P < 0.05. C: Quantitative analysis of branch number per tubular structure. Values are the mean ± SE (n = 5).
