4-Methylimidazole (4-MI) is found in a great number of food products. The National Toxicology Program (NTP) revealed that 4-MI is carcinogenic and can also cause anemia and weight loss. Mesenchymal stem cells (MSCs) are able to support hematopoiesis and migrate to the site of tumors. To investigate whether 4-MI has an impact on MSCs, we have measured the ability of cell (osteoblast, adipocyte) proliferation, apoptosis, cell cycle, gene expression, migration and differentiation between control group and the 4-MI group. The results showed that higher concentrations of 4-MI (≥150 μg/ml) had significant effects on BMSCs viability while lower concentrations (≤100 μg/ml) had no significant effects on cell proliferation, apoptosis, migration, differentiation, and expression of relevant marker genes of hematopoietic cytokines, including TPO, SCF, VEGF and FLt3. The results also indicated that 4-MI (≤100 μg/ml) may have no significant effect on the biological characteristics of MSCs. Low concentration of 4-MI in foods and beverages have no toxic effect on BMSCs. The anemia and weight loss of animals caused by 4-MI may not be due to its effect on BMSCs.
