Figure Lengend Snippet: Establishment of DUB-loaded bone-targeted liposomal delivery system. ( A ) Representative images and quantitative analysis of mineralized nodule formation via Alizarin Red S (ARS) staining in primary BMSCs for the effect of DUB@Lip on osteogenesis differentiation under conditions of 10 μM Dex. ( B ) RT-qPCR for the expression of osteogenesis-related genes in primary BMSCs of different groups. ( C-D ) In vitro cellular uptake assay of IR-780-labeled DUB@Lip liposomes in primary BMSCs by confocal microscopy and flow cytometry. ( E-F ) Evaluation of bone-targeting capacity and pharmacokinetic analysis of DUB@Lip and DUB@TLip via ex vivo fluorescence imaging. ( G-H ) Representative reconstructed images and quantification for Tb.BV/TV, Tb.N, Tb.Th, Tb.Sp, and Ct.Th in femora in mice of different groups by Micro-CT. ( I ) H&E staining and quantification for trabecular bone area in distal femora in mice of different groups. ( J ) Masson staining and quantification for collagen deposition fraction (collagen area/trabecular bone area) in distal femora in mice of different groups. n = 4 independent repeats by using different biological samples in each group for in vitro experiments, or 8 mice per group for in vivo assays. Data were means ± s.e.m. ns p > 0.05, ∗ p < 0.05, ∗∗ p < 0.01, ∗∗∗ p < 0.001 by one-way ANOVA. Scale bars: 200 μm (A-B), 2 mm (G left & right bottom), 1 mm (G right top), and 100 μm (I-J).

Article Snippet: To prepare non-targeted DUB-loaded liposomes, DSPE-PEG2000-ALN was substituted with an equimolar amount of DSPE-mPEG2000 (HY-142978, MedChemExpress, Shanghai, China) using the same preparation procedure.
