Figure Lengend Snippet: Expression of cell-cycle regulation and proliferation genes ( a ) CDKN1A , ( b ) CDKN2A , ( c ) MKI67 , ( d ) H2AFX , and ( e ) VEGFA in irradiated HDFs (10 Gy) treated with exosomes (1 × 10 9 particles/mL) derived from BM-MSCs (BM-IR) and UC-MSCs (UC-IR), measured by qPCR. Gene expression was normalized to GAPDH and expressed as fold change relative to the non-irradiated Vehicle control at each timepoint. Data are shown as mean ± SD of three technical replicates from a representative experiment performed using a single HDF donor. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001 by ordinary one-way ANOVA followed by Dunnett’s post hoc test, comparing each treatment group to the Vehicle-IR control at the corresponding timepoint.
