From: Angiogenic properties of aged adipose derived mesenchymal stem cells after hypoxic conditioning
Effect of age and hypoxic stimulation on urokinase system factors gene expression. Expression levels of MMP2 (A), MMP9 (B), uPAR (C) and uPA (D) were measured using qRT-PCR. Animal groups consisted of young (1-3 month, 16 animals), aged (18 months, 9 animals) and old mice (24 months, 7 animals). Results are means of different animals (* = p < 0.05, ** = p < 0.01, *** = p < 0.001).
