| In Vitro | Hexadimethrine bromide inhibits human mesenchymal stem cell proliferation during lentiviral transduction. Hexadimethrine bromide is considered non-toxic at low concentrations, but has been found to negatively affect cell proliferation in some cell types at concentrations greater than 10 µg/mL. Trypsinized cells exposed to Hexadimethrine bromide are visibly larger in size when viewed under the microscope[1]. |
| Cell Assay | Trypsinized cells are washed and resuspended in medium at 2×104 cells/mL with or without rhFGF-2 (final concentration=10 ng/mL, PeproTech) and with or without Hexadimethrine bromide at a final Hexadimethrine bromide concentration of 1, 4, or 8 µg/mL. The different conditions are seeded in 96-well plates at 1×103 cells in 50 µL per well in triplicate and cultured at 37°C, 5% CO2. After 6, 9, or 24 hr, the medium is changed and subsequent medium changes occurred every 3-4 days with 50 µL of ± FGF-2 medium (10 ng/mL). Plates are harvested on day 4, 7, 14, and 21 by removing the medium and placing the plates in the -80°C freezer until the day of analysis. The CyQUANT assay is then performed on the wells[1]. |
