FIGURE 3.

Expression of pro‐fibrotic genes across the life course by sex. (a) Fibronectin (FN1) expression was lower in aged female mice compared to adult, but not different in males. (b) Periostin (POSTN) expression in females was higher in adulthood but lower in aged with no differences observed in males (c) Alpha‐1 type I collagen (COL1A1) expression in females was lower in aged mice compared to adults and juvenile but lower in adults and aged compared to juvenile in males. n = 6 per group. *p<0.05, **p<0.01, ***p<0.001 by one‐way ANOVA
