Abstract (original English)

Background Emu oil (EO) with anti-inflammatory, antioxidative, and wound healing properties can be blended for preparing bioactive nanofibrous scaffold. Adipose tissue-derived stem cells (ADSCs) are promising candidates for tissue engineering, and preserving their stemness potential is vital for further therapeutic applications. Aim The aim of this study was to fabricate EO-blended nanofiber and investigate its effect on proliferation, survival, and stemness preservation of ADSCs. Materials and methods Pure EO composition was characterized using a gas chromatograph mass spectrometer. EO-PCL-polyethylene glycol (PEG) nanofibers were successfully fabricated using an electrospinning technique and characterized by field emission scanning electron microscopy (FE-SEM) and fourier-transform infrared spectroscopy (FTIR). Cell viability and adhesion were measured using the MTT assay and FE-SEM. Finally, quantitative PCR (qPCR) was used to quantify the expression level of cell cycle regulated genes and pluripotency-associated transcription factors. Results Findings showed that 20% (w/w) of EO is the optimum oil content in the electrospun solution to achieve good morphology and ultrafine fibers. The relatively high optical densities and FE-SEM images indicated that EO highly supported cell adhesion and proliferation on the matrices. In addition, EO-PCL-PEG electrospun nanofibrous mats sig
