Effect of Nonsteroidal Anti-inflammatory Drugs on the Osteogenic Activity of Osteoprogenitor Cells Cultured on Titanium Surfaces.

Effect of Nonsteroidal Anti-inflammatory Drugs on the Osteogenic Activity of Osteoprogenitor Cells Cultured on Titanium Surfaces. Int J Oral Maxillofac Implants. 2019 Feb 19;: Authors: Luo JD, Miller C, Sharma D Abstract PURPOSE: The purpose of this study was to investigate the effects of celecoxib and ibuprofen on the proliferation, viability, and migration of MC3T3-E1 cells cultured on titanium surfaces. MATERIALS AND METHODS: MC3T3-E1 cells were cultured on sandblasted titanium disks and allocated to one of the following interventional groups: (a) control (untreated group); (b) celecoxib (5 μM and 10 μM); (c) ibuprofen (5 μM and 10 μM); and (d) prostaglandin E2 (10 μM). Proliferation of attached cells was assessed over 9 days using an AlamarBlue assay. A trypan blue exclusion test was conducted to assess cell viability, where the relative percentages of live and dead cells were quantified using a hemocytometer over 2 days. A Boyden-Chamber Assay was utilized to assess cell migration over 33 days. RESULTS: The proliferation of cells treated with any intervention was not significantly different than that of the untreated group throughout the treatment period. However, celecoxib and ibuprofen significantly decreased the percentage of viable cells in a dose-dependent manner. Specifically, celecoxib (10 μM) and ibuprofen (5 μM and 10 μM) on day 1, and celecoxib (10 μM) on day 2 showed significantly higher perce...
