Effect of daCO-DM modified 3D-printed module on neurogenesis. (a)Immunofluorescence of β3-Tubulin and NeuN showed nerve in vivo. Scale bar 20 μm. (b)Gene expressions of Ngf after 14 days of BMSCs culturing on DM modifed scaffolds. DM, decellularized matrix; none-DM, PCL; BMSC, bone marrow stromal cell; WTO, wild-type osteocytes; daCO, osteocyte with dominant active β-catenin. Sections with newly formed bone were measured for each mouse and 5 mice were analyzed for each group. Data were expressed as mean ± SD. *p < 0.05 v.s. none-DM;#p < 0.05 v.s. BMSC-DM, $p < 0.05 v.s. WTO-DM by one way ANOVA.
