Effect of aging on ALDH activity. A Percentages of CD45−/ALDHbr and CD45−/ALDHbr/PDGFRα+ cells in total lung cells during BLM-induced pulmonary fibrosis in young and aged mice (n = 4–6). *P < 0.05, **P < 0.01. ns, not significant. B ALDH activity in primary cultured lung fibroblasts obtained from young and aged mice (n = 5–10) before and 7 days after treatment with BLM. **P < 0.01. ns, not significant
