Abstract

Adipogenesis is preceded by development of a microvascular network, and optimal functioning of adipose tissue as an energy store and endocrine organ is dependent on extensive vascularization. We have examined the role of endothelial cell-derived factors that influence the proliferation of human preadipocytes. Microvascular endothelial cells and preadipocytes were isolated from human omental and subcutaneous adipose tissue biopsies by use of a developed procedure of collagenase digest, immunoselection, and differential trypsinization. Conditioned medium from microvascular endothelial cell cultures promoted the proliferation of preadipocytes (P = <0.001) and (to a lesser extent) other cell types. No depot-specific differences in mitogenic capacity of microvascular endothelial cell medium or of preadipocyte response were observed. These results indicate that adipose tissue endothelial cells secrete soluble adipogenic factor(s).

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
