In-vivo ABCB5⁺ MSCs restore ER Ca²⁺ using the SERCA2a-PLN axis. A, B Representative SERCA2a, PLN, pPLN, and β-actin expression in bilateral gastrocnemius muscle (GM) samples from the 3 mice from control (A) and ABCB5 + MSC treated groups (B). Full-length blots are presented in Additional file 5: Fig. S5. C–E Densitometric quantification of C SERCA2a expression (normalized to left side), D PLN expression (normalized to left side) and E pPLN/PLN (normalized to left side). Data were represented as mean ± SD, n = 10 control and n = 12 in ABCB5⁺ MSCs group, ns, not significant, *p < 0.05
