Bone cells: a serum-free medium supports proliferation in primary culture.
Bone-cells isolated from embryonic rat calvaria increase in number two-to threefold when cultured at high, but not at low, population densities in a serum-free medium that contains albumin. Cultured cells respond to parathyroid hormone and exhibit a marked rise in alkaline phosphatase activity during proliferation, which suggests the progressive differentiation or preferential growth of osteoblast-like cells.
