In vivo repair effect of PLGA microspheres on IDD. A, B Observation of rat tail intervertebral disc in each group by safranine and fast green staining and classification analysis. C, D The COL2A1 expression level in NP tissues in the five groups were determined by immunohistochemistry and quantitative analysis. E, F Western blot was used to detect the difference in the expression of ACAN and COL2A1 protein in nucleus pulposus tissues with different degrees of degeneration (n ≥ 3, *p < 0.05, **p < 0.01)
