Özet

Aim: This study aims to produce electrospun nanofiber membranes containing human decellularized skin extracellular matrix (HdsECM) for use in wound healing and skin regeneration.

Method: Full-thickness skin tissues were obtained from discarded tissue under the Koc University Aesthetic and Reconstructive Surgery IRB protocol. Skin decellularization was carried out using enzymatic protocols. A polymer solution containing 2% alginate, 7% gelatin, and 1% HdsECM was used for membrane production. Voltage, distance, and flow rate parameters were optimized to obtain an ideal electrospun membrane. The porous structure was analyzed by a Scanning Electron Microscope (SEM). Mechanical properties and degradation kinetics were investigated. Bioavailability of the fabricated membrane was also performed using human keratinocyte cells.

Results / Discussion: An optimum nanoporous membrane was produced using the parameters of 1.00 mm/h, 216mm, and 22 kV for electrospinning technology. According to SEM images, it was observed that a uniform nanofiber structure was formed in the membranes. The membrane preserved its structural integrity for 7 days, and the keratinocyte cells survived for 14 days with their normal morphology.

Conclusion: The nanofiber electrospun membrane, including HdECM as an active agent, was tested as a wound dressing to assess its fundamental biological and physical features. Based on its properties, we conclude that the membrane has the potential in skin tissue engineering for regenerative and reconstructive medicine applications.
