Introduction: In this study, the production of APC-loaded nanofiber mats using the electrospinning method and examining the release of growth factors from the produced APC-loaded nanofiber mats was planned. Materials and Methods: APC-loaded composite nanofiber mats (n=5) were produced using the electrospinning system in textile engineering laboratory. The surfaces morphologies of the produced mat were examined using a scanning electron microscope. Studies for release were carried out at department of immunology. PBS (0.5 mL) was collected at 0, 48, 96, 144, 192, 240, 288 and 336 hour intervals for the analysis of growth factors to be released into PBS from APC-loaded nanofiber mat. Collected PBSs for quantitative analysis of growth factors and BCA (Bichchoninic acid) protein concentration analysis were stored at -20oC for analysis. The growth factors released from APC-loaded composite nanofiber mat into PBS at certain time intervals,
1- Epidermal growth factor, EGF;
2- Basic fibroblast growth factor, bFGF;
3- Platelet-Derived Growth Factor AA (PDGF-AA)
quantitative analyzes were performed with the technology laboratory ELISA Kit (Elabscience, USA) as recommended by the manufacturer. Results: When the release amounts between FGF, EGF and PDGF groups were compared, a significant difference was found in all time periods from the 48th hour to the 336th hour (respectively, p=0.004, p=0.008, p=0.006, p=0.009, p=0.009, p=0.009; p<0.05). When the time-dependent release changes within each group were examined, there was no statistically significant difference in the FGF group (p=0.084; p>0.05), but there was a significant difference between the EGF and PDGF groups (p=0.012, p=0.016; p<0.05). It was observed that there was a significant difference between the 48th hour and the 288th and 336th hours in the EGF group, and lower release occurred at these hours. In the comparison made for PDGF, it was seen that there was a significant difference between the 48th hour and the 192nd and 288th hour, and lower release was realized at these hours. Conclusion: It is thought that the results to be obtained from the research are useful in terms of using APC-loaded nanofiber mats as a wound dressing in future research and providing scientific data.
