Calvarial and limb bone cells in organ and monolayer culture do not show the same early responses to dynamic mechanical strain.

Abstract

Responses to mechanical strain in calvaria and limb bone organ cultures were compared by measuring cellular glucose 6-phosphate dehydrogenase (G6PD) activity in situ and prostaglandin release. Normal functional strains were recorded in the ulnae (1000 mu epsilon) and calvarium (30 mu epsilon) in vivo in 110 g rats. Organ cultures of ulnae and calvaria from… (More)
