Fig. 4From: G protein-coupled receptor kinase 3 modulates mesenchymal stem cell proliferation and differentiation through sphingosine-1-phosphate receptor regulationFemoral trabecular bone density is not differentially affected by GRK3 deficiency in young or aged mice. Quantification of trabecular bone volume fraction (BV/TV) via microcomputed tomography analysis of (A) young and (B) aged Grk3-/- and WT mouse femurs. Representative 3D image of trabecular bone of (C) young and (D) aged Grk3-/- and WT mouse femurs. Data represent mean ± SEM, n = 5 for young mice and n = 8 (WT) n = 11 (Grk3-/-) for aged female miceBack to article page
