Stmn-2, Mmp-3, and Mmp-12 increase more extensively with aging in perirenal than epididymal preadipocytes. Stathmin-like 2 (A), matrix metalloproteinase 3 (Mmp-3); (B), and Mmp-12 (C) mRNA levels in undifferentiated perirenal and epididymal preadipocytes cultured from young (3 months), middle-aged (17 months), and old (30 months) rats were assayed by real-time polymerase chain reaction (N = 7 animals in each group; *p < .05; Duncan’s multiple range test; data plotted from Figure 2A).
