Live/dead staining to assess the viability of rBMSCs cultured on the SHA, SMHA, SSHA, and SMSHA scaffolds (a–d), respectively. The CCK-8 assay assessed the proliferation of rBMSCs (e) (n = 5, * P < 0.05, # P > 0.05 compared with SHA). The surface area (f) and typical cell morphology (g–j) of rBMSCs cocultured with SHA, SMHA, SSHA, and SMSHA for 3 days, respectively (n = 5, * P < 0.05, # P > 0.05 compared with SHA)
