Abstract

PURPOSE: Adipose tissue contains a population of pluripotent stem cells capable of differentiating along multiple mesenchymal cell lineages. It is well known that fat depots from different part of our body shows different nature not only in morphological aspect but also physiologic aspect. The authors compared the adipogenic potentials and osteogenic potentials of adipose stem cells from different anatomical sites of human.
METHODS
After laparotomy by surgery team, the authors isolated these adipose stem cells successfully from 7 men with an average age of 58, and induced differentiation along adipogenic and osteogenic lineages in vitro. On the 14th day, cells cultured in adipogenic media differentiated into adipocytes in vitro, as evidenced by positive Oil Red O staining of lipid vacuoles. On the 21st day, cells cultured in osteogenic media differentiated into osteoblasts in vitro as demonstrated by Alizarin red staining of a calcified extracellular matrix.
RESULTS
After exposure to adipogenic and osteogenic differentiation medium, subcutaneous adipose stem cells were found to possess greater adipogenic and osteogenic potentials than cells isolated from visceral adipose tissues.
CONCLUSION
This study indicates that adipogenic and osteogenic potentials of adipose stem cells vary by their anatomical sites, with subcutaneous adipose stem cells exhibiting higher adipogenic and osteogenic potential than those isolated from visceral fat.
