Selenomethionine, a Trace Element, Increases Osteoblastic Activity of hFOB 1.19 Cells (an In Vitro Study).

Abstract

Osteoporosis and resulting fractures affect a significant group of people in the world. It has been shown in many studies that selenium has positive effects on bone metabolism. Based on this information, the aim of this study is to investigate whether bone differentiation will start in a shorter time by applying selenomethionine (SeMet) to hFOB cells.First, hFOB 1.19 cells were cultured. Safe doses of SeMet were determined by MTT and LDH tests. Ossification levels were determined by alizarin red staining and measurement of alkaline phosphatase enzyme levels. The results were analyzed with statistical tests.It was observed that SeMet increased cell viability at concentrations of 10, 25, 50, 100, and 200 µM in 24 h. At these concentrations, cell viability increased above the control, the viabilities were as follows: 109.4%, 104.9%, 104.3%, 103.15%, and 100.27%. High doses of SeMet significantly reduce cell viability. According to Alizarin red staining, SeMet increases the amount of calcium deposits in hFOB cells in a dose-dependent manner. In the experimental groups, the highest ALP enzyme was determined in the 7-day SeMet application. The most effective dose was measured as 15 µM.It was determined that SeMet, which is found as a trace element in living things in nature, increases the viability of hFOB cells, which are osteoblast cell precursors, and increases osteoblastic differentiation and osteoblastic activity in these cells. Our results are at a level that sheds light on an important problem in public health.
