Osteoclast Differentiation In Cocultures Of Chondrogenic Cell Line Rcj 3.1c5.18 And Mouse Or Rat Bone Marrow: Dependence On Culture Substrate And Association With Alkaline Phosphatase Positive Marrow Stromal Cells, G. I. Anderson, J. N. M. Heersche
Osteoclast Differentiation In Cocultures Of Chondrogenic Cell Line Rcj 3.1c5.18 And Mouse Or Rat Bone Marrow: Dependence On Culture Substrate And Association With Alkaline Phosphatase Positive Marrow Stromal Cells, G. I. Anderson, J. N. M. Heersche
Cells and Materials
We investigated the formation of tartrate-resistant acid phosphatase positive (TRAP+) colonies and multinucleated cells (MNCs) in rat and mouse marrow cultures alone and cocultured with the chondrogenic cell line, RCJ3.1C5.18 on different substrata. In mouse marrow cultured in 35 mm dishes, few TRAP+ MNCs developed, while in rat marrow cultures, many TRAP+ MNCs, which possessed calcitonin receptors and resorbed bone, developed. In both rat and mouse cultures, TRAP+ MNC first appeared at Day 4 and grew in number up to Day 8. When both marrows were cocultured with RC3.1C5.18 cells, TRAP+ colony numbers increased relative to marrow alone. In marrow …
