The vacuolar-type H+ adenosine triphosphatase (V-ATPase) plays an important role in cellular acidification and bone resorption by osteoclasts. However, the direct effect of bovine parathyroid hormone (bPTH) on V-ATPase has not yet been elucidated. The aim of the present study was to assess the effects of bPTH on V-ATPase and osteoclasts. Osteoclasts from bone marrow (BM)-derived monocytes of C5...

BACKGROUND AND PURPOSE Parathyroid hormone-related protein (PTHrP) is a vasodilator peptide. In addition, PTHrP appears to affect vascular growth and to be a mediator of inflammation in rheumatic and brain disorders. We examined the possible role of PTHrP in the inflammatory process in atherosclerosis METHODS We immunohistochemically analyzed the cellular localization of PTHrP, the type 1 PTH...

Mesenchymal stem cells give rise to osteoprogenitors that proliferate and differentiate into identifiable preosteoblasts, osteoblasts, bone lining cells and osteocytes. To identify and establish a molecular profile for the more primitive and uncharacterized cells in the lineage, relatively rare (<1%) osteoprogenitors present in primary cultures of fetal rat calvaria cell populations were identi...
