2a). Immunophenotype of CD146− CD29+, and CD146− CD34+ sorted GFP-Tg ASC subpopulations. Immunophenotypes were based on expression of CD29, CD31, CD34, CD45, CD11B, Sca-1, and CD105 surface antigens. 2c). Adipogenic differentiation, and 2d) colony formation assays of unfractionated GFP-Tg ASC, CD146− CD29+ GFP-Tg ASC, and CD146− CD34+ GFP-Tg ASC. All experiments were repeated in triplicate; sample size, n=3 per replicate. Values reported as mean ± standard deviation (µ ± SD); *p < 0.05, ** p < 0.01; ***p < 0.001.
