Electroacupuncture of Weizhong (BL-40) acupoint significantly increased PAX7 positive cells. (a) Representative images of FITC labeled PAX7 flow cytometry analysis of the back muscle of the following groups. YS: young sham group (n = 8); YI: young injured group (n = 7); YI + WZ: young injured rats treated with electroacupuncture of Weizhong (BL-40) acupoint (n = 7); YI + NWZ: young injured rats treated with electroacupuncture of Non-Weizhong (BL-40) acupoint (n = 7); AS: aged sham group (n = 8); AI: aged injured rats (n = 7); AI + WZ: aged injured rats treated with electroacupuncture of Weizhong (BL-40) acupoint (n = 7); AI + NWZ: aged injured rats treated with electroacupuncture of Non-Weizhong (BL-40) acupoint (n = 7). The electroacupuncture may last for 10 days after the rat back muscle is injured for 5 days. Scale bar, 100 μm. (b) Quantification analysis of average PAX7 positive cells of all rats (n = 8 in young sham and aged sham groups, n = 7 in other groups). All data are represented as the Mean ± SD. The student's t-test was used for all statistical analyses (^ϯϯϯP < 0.001,^###P < 0.001,^##P < 0.01).
