Fig 4

(A): Nuclei morphology of fibroblasts at the tendon (magnification; X400) (B): Density of fibroblasts of the tendon. (C): Nuclear aspect ratio of fibroblasts of the tendon. (D): Nuclear angle of fibroblasts of the tendon. (E): Saf-O staining of the tendon (magnification; X200). (F): Area of cartilage-related GAG of the tendon. Bar charts present mean ± standard deviation; statistically significant at p < .05. Abbreviations: UC MSCs, umbilical cord derived mesenchymal; GAG, glycosaminoglycan; Saf-O, safranin-O.
