FIG. 3.

(A) HUVEC monoculture on CPC at 42 days was immunostained for PECAM1. HUVEC attached well to macroporous CPC and proliferated and increased the coverage on the CPC surface. HUVEC distributed randomly as clumps or monolayers of cells, with no microcapillary-like structures on CPC. (B) Comparison of monoculture with coculture on macroporous CPC for microcapillary-like structure formation. The cumulative length of microcapillaries in each image was measured and divided by the area of the image (mean±SD; n=6). Color images available online at www.liebertpub.com/tea
