Fig. 6From: Can supernatant from immortalized adipose tissue MSC replace cell therapy? An in vitro study in chronic wounds modelProliferative activity of concentrated HATMSC supernatants in in vitro model of the chronic wound. Metabolic activity of MSU-1.1, HSkMEC.2, and HaCaT cells cultured in serum-free medium and 1% O2 was measured by MTT assay at days 0, 1, 2 and 3 following treatment with 1, 5, 10, and 15 μg of concentrated HATMSC supernatants. Untreated cells were used as a control. Data represents mean ± SEM, n = 3; *p < 0.05, **p < 0.01, ***p < 0.001Back to article page
