Fig. 1: Dynamic changes in levels of bone marrow (BM) progenitor cells and decrease of CACs in diabetic mice.

Mononuclear cells from peripheral blood or the BM of diabetic (DM) mice at 1, 3, 6, and 9 months after the onset of diabetes and their respective non-diabetic (NDM) controls were separated by Ficoll gradient centrifugation. a Numbers of CACs (Flk-1+/Sca-1+/CD34+) in the peripheral blood. b Numbers of BM-HSCs (Lin−/c-Kit+/Sca-1+/CD34+). c Numbers of BM-CACs (Flk-1+/Sca-1+/CD34+; n = 3–6 mice per group). All data are presented as mean ± SD. *P < 0.05, ***P < 0.001 vs. age-matched NDM control mice (two-way ANOVA with bonferroni post hoc test)
