Fig. 11. TPA promotes EC tube morphogenesis through PKC. ECs were suspended in collagen matrices for 24 hours in the absence and presence of PKC inhibitors GF109203X (2.5 µM), Ro-32-0432 (5 µM), Go6983 (5 µM) or Go6976 (5 µM). (A) Quantification of the mean number of EC lumens per HPF±s.d. (n=2). *, P<0.08 compared with the TPA control. (B) Tracing of the mean EC lumenal area (Metamorph software)±s.d (n=2). *, P<0.05 compared with control TPA.
