Caption A: Subtle delay of fifth middle phalanx ossification in newborn Lrp5tm1Kry/Lrp5tm1Kry mice. B: Delayed ossification of metacarpals. C: Carpals (bracket). D: Humeri in 4 day old mutant mice. Arrows in A, B and D indicate ossification centers. A subtle delay was also evident in 44% (8/18) of Lrp5tm1Kry/Lrp5+ mice (D, middle). E: Sections of calvaria from 4 day old mice showing a decreased number of BrdU-positive cells (arrowhead) in homozygous mutant mice compared with wild type littermates. Double-headed arrows indicate the greater thickness of wild type calvarium. F: Osteoblast mitotic index (percentage of BrdU-positive cells per total cell number) in wild type and homozygous mutant mice (n = 8 per genotype). G: Quantification of allkaline phosphatase positive stromal cell progenitors (CFU-F) in the bone marrow of wild type and homozygous mutant mice (n=9 mice per genotype). H: Quantification of apoptotic cells by TUNEL assay in wild type and homozygous mice (n = 5 per genotype). I: Northern blot analysis of Cbfa1 expression in calvaria, long bones, and primary osteoblasts. J: Northern blot analysis of Osteocalcin expression in calvaria and long bones. I and J: Gapdh expression level was used as a loading control; results are representative of three samples (n = 3 mice per sample). Asterisks indicate a statistically significant difference between two groups of mice (p<0.05). Error bars represent SD.
