The Investigation of Proliferation of Fibroblasts on Chitosan Scaffold in the Presence of Hyaluronic Acid
Abstract
Background & Aim: Tissue engineering is a new method for the replacement of degraded tissue components by biodegradable polymers, which is provided as a three-dimensional scaffold for growth and proliferation of stem cells. In this study, chitosan scaffold was used to evaluate the proliferation of fibroblasts in the presence of hyaluronic acid. Methods: In this experimental study, powder scaffolds were prepared for growth of fibroblastic cells. The following groups were designed for later studies: Group 1: Chitosan scaffold with hyaluronic acid, Group 2: Chitosan without hyaluronic acid scaffold, Group 3 (control 1): Hyaluronic acid fibroblast cell and Group 4 (control 2): Hyaluronic acid fibroblaster cell. The human foreskin was prepared and the fibroblasts of the dermal layer were removed after separation, and the cells were transferred to the culture flasks with DMEM medium and stored in a CO2-containing incubator. After several passages, 10,000 cells were transferred to 96 wells containing DMEM medium and MTT and DAPI staining method was used to amplify fibroblasts on the chitosan scaffold. The obtained results were analyzed by ANOVA and Tukey's post hoc test after uniformity of data analysis. Results: The mean survival rate of chitosan without hyaluronic acid scaffold in 24 hours was significantly higher than that of control with and without hyaluronic acid and chitosan group with hyaluronic acid (P <0.05). The mean survival in the control group without hyaluronic acid increased significantly in 48 hours compared to the chitosan scaffold with and without hyaluronic acid and the control group with hyaluronic acid (P <0.05). The mean survival time in chitosan scaffold with and without hyaluronic acid in 72 hours was not statistically significant compared to control groups with and without hyaluronic acid. Conclusion: Chitosan scaffold showed better biocompatibility with fibroblasts due to its hydrophilic property, but the presence of hyaluronic acid with chitosan reduced the fibroblast growth trend. Chitosan may be alone in structures that are synthesized to repair damaged areas of the skin, a good scaffold for proliferation of damaged fibroblast cells.
