Abstract

Objective: Adipose-derived stem cells (ASCs) isolated from subcutaneous adipose tissue have been tested in clinical trials. However, ASCs isolated by enzyme digestion and centrifugation are heterogeneous and exhibit wide variation in regenerative potential and clinical outcomes. Therefore, we developed a new method for isolating clonal ASCs (cASCs) that does not use enzyme digestion or centrifugation steps. Research design and methods: In addition to cell surface markers and differentiation potential, we compared the mitogenic, paracrine and hair growth-promoting effects of ASCs isolated by the gradient centrifugation method (GCM) or by the new subfractionation culturing method (SCM). Results: We selected three cASCs isolated by SCM that showed high rates of proliferation. The cell surface markers expressed by ASCs isolated by GCM or SCM were very similar, and SCM-isolated ASCs could potentially differentiate into different cell lineages. However, cASC lines exhibited better mitogenic and paracrine effects than ASCs isolated by GCM. The expression of Diras3, Myb, Cdca7, Mki67, Rrm2, Cdk1 and Ccna2, which may play a key role in cASC proliferation, was upregulated in cASCs. In addition, cASCs exhibited enhanced hair growth-promoting effects in dermal papilla cells and animal experiments. Conclusions: SCM generates a highly homogeneous population of ASCs via a simple and effective procedure that can be used in therapeutic settings.
