Effect of ibuprofen on osteoblast differentiation of porcine bone marrow-derived progenitor cells. [Comparative Study, Journal Article, Research Support, Non-U.S. Gov't]
J Oral Maxillofac Surg 2009 Nov; 67(11):2412-7.
PURPOSE: Nonsteroidal anti-inflammatory drugs are commonly prescribed to reduce inflammation and pain. However, little is known about the direct effect of these drugs on the differentiation of bone marrow-derived progenitor cells into osteoblasts. The purpose of this study was to determine the effect of ibuprofen on osteoblast differentiation and proliferation in a minipig model.
MATERIALS AND METHODS: Bone marrow was aspirated from the minipig ilium, and porcine bone marrow-derived progenitor cells (pBMPCs) were isolated and expanded in standard culture medium. The pBMPCs were replated and differentiated into osteoblasts by use of osteogenic supplements (OS). Five groups were studied: negative control--pBMPCs in standard medium only; positive control--pBMPCs, standard culture medium, and OS; and 3 experimental groups--pBMPCs, standard culture medium, OS, and ibuprofen added in doses of 0.1, 1.0, and 3.0 mmol/L. Cell cultures were evaluated quantitatively by alkaline phosphatase (ALP) stain, von Kossa stain, and deoxyribonucleic acid (DNA) content.
RESULTS: pBMPCs cultured with OS and low-dose ibuprofen (0.1 mmol/L) showed ALP stain, von Kossa stain, and DNA content similar to pBMPCs cultured in OS (positive control). pBMPCs cultured in higher doses of ibuprofen (1.0 and 3.0 mmol/L) produced significantly less positive staining of ALP and von Kossa and decreased DNA content.
CONCLUSION: The results indicate that high-dose ibuprofen has a deleterious effect on pBMPC differentiation into osteoblasts whereas low-dose ibuprofen does not. The low dose of 0.1 mmol/L is the typical serum level when prescribed for clinical use.
