Example 1
Isolation and Culture of hADSCs
After obtaining informed consent from all the patients and approval from the Kaohsiung Medical university hospital ethics committee, leftover subcutaneous adipose tissue was acquired from patients undergoing orthopedic surgery. The hADSCs were isolated from human subcutaneous adipose tissue following the previously described method (Fehrer and Lepperdinger, Exp Gerontol, 2005, 40:926-930). The isolated hADSCs were cultured and expanded at 37 C under 5% CO2 in K-NAC medium containing Keratinocyte-SFM (Gibco BRL, Rockville, Md.) supplemented with the EGF-BPE (Gibco BRL, Rockville, Md.), N-acetyl-L-cysteine, L-ascorbic acid 2-phosphate sequimagnesium salt (Sigma, St. Louis, Mo.) and 5% FBS (Fehrer and Lepperdinger, Exp Gerontol, 2005, 40:926-930).
