Autologous Serum and human Epidermal Growth Factor (hEGF) Accelerate Keratinocyte Proliferation and Migration during Re-epithelialization Process

Autologous serum is used as a therapeutic approach recommended to treat certain types of chronic diseases that can even last a lifetime. Autologous scrum contains Epidermal Growth Factor (EGF), which can stimulate the migration and proliferation of keratinocytes in the re-epithelialization process in wound healing. The addition of hEGF on autologous scrum is a part of efforts to accelerate the wound healing process. Tests were performed by measuring proliferation and migration activities of keratinocytes cells using HaCaT cell line. The cell proliferation was measured using Water Soluble Tetrazolium-8 (WST-8) method while the cell migration was measured using Scratch Assay method. Variations in the concentration of hEGF added were 0.5, 1, 5, 10, 25, and 50 ng / mL. There were significant differences in the results of cell proliferation in hEGF-added HaCaTcells and the optimum concentration was seen in 25 ng/mL hEGF group (p <0.05). On the contrary, the addition of various concentrations of hEGF in autologous serum resulted in no significant difference in HaCaT cell proliferation (p>0, 05). The addition of hEGF and autologous serum showed a visible role in accelerating the pace of cell migration. Within 18 hours, the percentage of cell migration in HaCaT cells added by hEGF and autologous serum reaches 55-70% and then 65-80% within 24 hours while HaCaT
