Expression of CD markers in freshly isolated and expanded (passage 1) Sk-Cs. (A) Freshly isolated total cells were positive for 6 out of 11 markers, and predominant markers were CD29 and CD34; thus, these were used for subsequent cell fractionation. However, expression of these markers markedly changed after culture of both Sk-DN/29+ and Sk-34/29+/− cells, but importantly, the characteristics of both cells were similar after expansion. (B) Actual sorting for the exclusion of CD45+ cells, as hematopoietic cells. (C) Basic sorting pattern of 3 cell fractions, as Sk-DN/29+, Sk-34/29+ and Sk-34/29, which was consistently used throughout the present study. Data were obtained from 21 subjects/32 samples (Male n = 19, age 21–79; Female n = 2, age 17–69, from abdominal muscle n = 16, leg muscles n = 5).
