Role of oestrogen in the development of osteoporosis.

abstract：:Extracellular ATP, and to a lesser extent adenosine, an ATP metabolite, stimulated cell proliferation in osteoblast-like cells (MC3T3-E1). ATP increased cytosolic Ca2+ due to Ca2+ mobilization from intracellular storage in the same concentration range of the nucleotide as that effective for DNA synthesis, suggesting t...
