Abstract

This study was purpose to examine the effect of dimethyl sulfoxide (DMSO) and Tween 80 on the growth and viability of stromal cells (BMSC), colony-forming units for granulocytes and macrophages (CFU-GM) and bone marrow endothelial cell line (BMEC) from murine bone marrow in vitro, and to analyze the concentration-effect relationship. The colony yields of colony-forming units fibroblastic (CFU-F) and CFU-GM were assessed in the murine bone marrow cell cultures at various concentrations of DMSO or Tween 80 and in the control groups. The MTT assay and trypan blue exclusion were used to determine the cell viability and percentage of survival in BMSC and BMEC cultures with or without either of these organic solvents. The results showed that the colony yields of both CFU-F and CFU-GM were decreased significantly (p<0.05 or <0.01) at the concentrations (v/v final) of 2% DMSO or 0.005%-0.01% Tween 80 respectively, as compared with control. The cell viability and percentage of survival of BMSC and BMEC cultures were significantly reduced (p<0.05 or <0.01) at 0.5%-1.0% DMSO or 0.002%-0.005% Tween 80, as compared with control. With the increase of volume fractions of these solvents, the decreased percentages of corresponding measurements were increased by degrees. It is concluded that when the concentration of DMSO or Tween 80 goes to a certain level in cell culture medium, either of the organic solvents has an inhibitory action or/and cytotoxicity on the growth and viability of BMSCs, CFU-GM and BMECs. The growth inhibition and cytotoxic response are more significant at higher concentrations of these solvents.
