1 Osteocalcin synthesis by human osteoblasts from normal and osteoarthritic bone after vitamin D3 stimulation. Cholecalciferol bone gamma-carboxyglutamate protein Homo sapiens
2 In this study we correlated osteocalcin production from human osteoblasts isolated from healthy and osteoarthritic subjects to the degree of cartilage damage, before and after stimulation with 1,25(OH)2-vitamin D3, the active metabolite of vitamin D3. Cholecalciferol bone gamma-carboxyglutamate protein Homo sapiens
3 We determined the osteocalcin production in normal and osteoarthritic osteoblasts from maximal and minimal cartilage damage areas both under basal conditions and after vitamin D3 stimulation. Cholecalciferol bone gamma-carboxyglutamate protein Homo sapiens
4 The response of osteoblasts to vitamin D3 stimulation appeared to be proportional to the degree of joint damage, as the vitamin D3-induced increase in osteocalcin is proportionally greater in maximally damaged osteoblasts compared to minimally damaged ones. Cholecalciferol bone gamma-carboxyglutamate protein Homo sapiens
5 The response of osteoblasts to vitamin D3 stimulation appeared to be proportional to the degree of joint damage, as the vitamin D3-induced increase in osteocalcin is proportionally greater in maximally damaged osteoblasts compared to minimally damaged ones. Cholecalciferol bone gamma-carboxyglutamate protein Homo sapiens
6 Thus, after vitamin D3 stimulation, a significant increase in osteocalcin production by maximally damaged osteoblasts compared to the minimally damaged ones was observed. Cholecalciferol bone gamma-carboxyglutamate protein Homo sapiens
