Apoptosis results of SCI rats after bFGF-ASC-HP hydrogel treatment.

(A)The expression of Caspase-3 in the immunohistochemical staining (×200 scale bar, 100 μm) and immunofluorescence results of the TUNEL assay (×400, scale bar, 50 μm). a: Sham group; b: SCI group; c: ASC-HP hydrogel group; d: bFGF solution group; e: bFGF-ASC-HP hydrogel group. (B) Analysis of the positive cells of the immunohistochemistry results and the analysis of apoptosis cell by bFGF-ASC-HP hydrogel treatment after spinal cord injury. All experiments were performed in three repetitions. Data are presented as Mean ± SEM, n = 5. *P < 0.05, **P < 0.01 and ***P < 0.01.
