H-Arg-Gly-Asp-Cys-OH is a tetrapeptide that contains the arginine-glycine-aspartate (RGD) motif, a sequence that acts as a recognition site for various adhesion proteins.1 It inhibits the binding of fibrinogen to endothelial cells and ADP-stimulated platelets with IC50 values of 320 and 35 ?M, respectively.2 Implantation of titanium rods coated with H-Arg-Gly-Asp-Cys-OH increases bone formation in rat femurs.3 H-Arg-Gly-Asp-Cys-OH has been conjugated to polyethylenimine to improve gene transfection efficiency.4

Cell experiment: | Human precursor dermal fibroblasts (HDF, human dermal progenitor cells, 12 week male donor) are use in the assay. WST-1 assay is used to assess the viability of HDF when incubated with chitosan derivatives. For this study, HDF are seeded in a 96-well plate at a density of 6×103 cells/cm2. To each well, 100 μL of cell suspension is added and incubated for 48 h in order to allow cell attachment. DMEM is then replaced by 100 μL of CMTMC and RGDC-DAH-CMTMC suspension at concentrations of 0.25 mg/mL, 0.5 mg/mL and 1 mg/mL, respectively. Cell viability under polymer incubation is evaluated during 2, 4 and 7 days. SDS (1%) is used as negative control. The polymer solution is changed every 3 days. 100 μL of WST-1 (1:10 dilution in DMEM) are added in each well after removing the polymer suspension and incubated for 0.5-2 h. Absorbance is recorded with a BioTek Microplate reader at two different wavelengths (450 and 690 nm). The viability is presented as percentage compared to the positive control group (cells in DMEM supplemented with 10% fetal calf serum). All experiments are carried out in triplicates. |
