these results , in conjunction with our previous demonstration of an endothelial cell mitogen produced by 3t3 adipocytes [ castellot , j. j. , jr. , karnovsky , m. j . & spiegelman , b. m. ( 1980 ) proc . natl . acad . sci . usa 77 , 6007-6011 ] indicate that the differentiation of these cells is closely linked to the production of factors that stimulate angiogenesis in vivo and growth and chemotaxis of endothelial cells in vitro .
