Skin Regeneration by Hybrid Carboxyl Methyl Cellulose/Calcium Alginate Fibers Electrospun Scaffold
JOURNAL OF NATURAL FIBERS(2022)
摘要
This study aimed to investigate on elasticity, degradation, and mechanical strength of sodium carboxyl methyl cellulose (SCMC) and calcium alginate (CA)-based scaffolds and their effect on fibroblasts' proliferation and adhesion. Using electrospinning technique by employing natural polymers provides a progressive approach in tissue engineering by producing similar structure with adjustable properties. Scanning electron microscope (SEM) was applied to observe the morphological and textural properties. Physico-chemical properties were studied using FTIR, tensile strain, contact angle, in vitro degradation, and water absorption test, and the biological properties were conducted by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and SEM observations. The results showed that a bead-free fibers was produced with over 80% porosity. CA resulted in enhancing elasticity, wettability, water uptake absorption, and increasing the rate of biodegradation. Biological assessment revealed that fibroblast cells were adhered and proliferated on SCMC/CA scaffold better comparable with pure SCMC scaffold. The overall findings denoted to the chemical, mechanical, hydrophilicity and biological suitability of SCMC/CA nanofiber scaffolds that make it a promising candidate for further studies toward skin tissue engineering applications.
