The GelMA gel and silica nanospheres. Gelatinous GelMA could be solidified by UV light (a). The silica nanospheres under SEM observation (b, c) and EDS analysis showed their pure silica content (d) and the controlled release of SrR for up to 7 days (e). The silica nanospheres and GelMA did not influence the BMSCs cell viability (f), and the drug-loaded group had a significantly higher gene expression of Sox-9 and reduction of β-catenin, while LiCl could significantly impress the expression of Sox-9 (g)
