Early moderate exercise increases the number of cardiac telocytes in the border zone but not in the infarct zone. (I) Immunofluorescence staining for PDGFRα⁺/CD34⁺ revealed that the density of CTs in the early moderate exercise group was slightly increased compared with that in the sedentary group; however, the difference was not statistically significant. (II) Immunofluorescence staining for PDGFRα⁺/CD34⁺ revealed that, in the border zone, the density of CTs in the early moderate exercise group was significantly increased compared with that in the sedentary group. (a1‐4) Sedentary heart. (b1‐4) Early moderate exercise heart. (c) Semiquantification of (I) and (II). n = 5 per group. The animals were trained on early moderate exercise for two weeks beginning one day after MI
