## Abstract Calcium transport was studied in bone cells isolated from fetal rat calvaria. ^45^Ca uptake experiments revealed an active component of calcium exchange. Calcium uptake was inhibited by iodoacetamide, DNP, CCCP and oligomycin and appeared to be dependent on medium phosphate concentratio

## Abstract Bone cells were isolated by collagenaseβhyaluronidase digestion of 19β20 dayβold fetal rat calvaria. It is shown that contamination from calcified matrix can give erroneously high values for total cell calcium and can mask intracellular calcium exchange. Filtration of the cell suspensi
The central role of the vitamin D endocrine system in calcium homeostasis is now well established [DeLuca and Schnoes, 1983; Kumar, 19841. Research during the early part of this century demonstrated the critical role of the fat-soluble vitamin, vitamin D, in preventing rickets [Mellanby, 1919; McCol
