Cell cycles in different experimental groups detected by flow cytometry. Cell cycles were detected by flow cytometry, and the results are indicated by the haploid number. Cells in the YCG were mainly haploid; cells in the NAG were mainly diploid, while the haploid cells were significantly decreased (P < 0.05); and the rate of haploid cells was significantly higher in the SWY1G and SWY2G than in the NAG (P < 0.05).1c: haploid; 2c: diploid; 4c: tetraploid. a: young control group (YCG); b: natural aging group (NAG); c: Heshouwuyin group 1 (SWY1G); d: Heshouwuyin group 2 (SWY2G). Each histogram represents the mean ± SD (n = 5). Columns with different letters represent significantly different values, while the same letters indicate no significant difference
