Figure Lengend Snippet: FVIII -/- mice suffer from osteoporosis and show altered bone vascularization with reduced osteoblastic cells. a Bone parameters, X-ray tomodensitometry analysis. Bone density images were obtained using the DataViewer software (Bruker) and represent sagittal, coronal, and transversal views of femurs. Parameters were analyzed at the growth plate level of the distal epiphysis of the femurs (metaphyseal). The same point of reference (chrondocyte seam) at the growth plate was established for each sample, from an offset of 0.215 mm from the growth plate and a trabecular volume of 1.5 mm 3 was selected for the analysis of bone morphometric parameters. b Bone vascularization parameters analyzed from trabecular bone sections (Endomucin in green, NG2 in purple, α- SMA in red, Dapi in blue). Light grey: WT mice, dark grey: FVIII -/- mice, BMD bone mineral density, BV/TV bone volume/total volume, Tb.Th trabecular thickness, Tb. N trabecular number, Tb.Sp trabecular space, Cor coronal, Sag sagittal, Trans transversal, up to 11 mice per group, one to four sections per bone analyzed. Mice were 5 (juvenile) or 14 (young adult) weeks old at sacrifice. * P < 0.05, ** P < 0.01, *** P < 0.001, ns not significant. Statistical test used: non-parametric Mann-Whitney test. Mean ± SD
