摘要

Human adipose-derived stem cells (hASCs) formed three-dimensional cell masses (3DCM) on FGF-immobilized surface and released angiogenic factors, such as VEGF, angiogenin, and IL-8. The 3DCMs of hASCs were CD3l~+ KDR~+, and CD34~+. Tubular microvessels perfused with blood were observed in the 3DCM/gel 3 weeks after injection and were recognized by antibodies against human a-SMA, KDR, CD31, and CD34, but not by antibodies against murine antigens. These results suggest that the vasculatures originated from the embedded human cells. The 3DCMs of hASCs could function as a source of vascular cells for neovascularization, and could also be co-implanted with other cell types for regenerative medicine.
