**Identification of human subcutaneous adipose stem cells**

Multiple cell-surface makers were demonstrated for ASC identification. The ASC immunophenotype should display the following typical marker profile for stromal cells: CD44, CD73, CD13, CD90, CD29 positive, and CD34 positive, but CD31, and CD45 negative [9]. Subcutaneous-ASC markers included CD10 and CD141 as potential cell-surface makers [10].

Compared with visceral-ASCs, subcutaneous-ASCs expressed a high level of CD90 and showed increases in proliferation, mitotic clonal expansion, and adipogenic differentiation. CD90 silencing inhibited proliferation and mitotic clonal expansion of subcutaneous-ASCs [1].
