In the extracellular space,
ecto-5′-nucleotidase (CD73) dephosphorylates adenosine triphosphate (ATP) to produce adenosine. Adenosine has four receptors namely A1R, A2AR A2BR and A3R. Adenosine plays a key role in the osteogenic differentiation. A1R induces osteoclast differentiation and A2AR induces osteoblast differentiation.

Adenosine has been used:
• as a supplement in embryonic type culture medium for in vitro osteogenic differentiation
• for evaluation of its effect on cell survival by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT assay) and cell proliferation by 3H-thymidine incorporation assay in multi drug resistant glioblastoma stem-like cells (GSCs), and as a standard in high performance liquid chromatography (HPLC).
• as a constituent in collagenase solution for the collagenase digestion of mice fat tissue.
