Abstract (original English)

An ideal biomaterial in regenerative medicine should be able to regulate the stem cell proliferation without the loss of its pluripotency. Chrysin (Chr) is a naturally occurring flavone with a wide spectrum of biological functions including anti-inflammatory and anti-oxidant properties. The present study describes the influence of Chr-loaded nanofibrous mats on the regulation of proliferation and stemness preservation of adipose-derived stem cells (ADSCs). For this purpose, Chr-loaded poly (ε-caprolactone)/poly (ethylene glycol) (PCL/PEG) nanofibrous mats were produced via electrospinning process and the successful fabrication of these bioactive mats was confirmed by field emission scanning electron microscopy (FE-SEM) and fourier transform infrared spectroscopy. ADSCs were seeded on the nanofibers and their morphology, viability, and stemness expression were analyzed using FE-SEM, MTT, and qPCR assays after 2 weeks of incubation, respectively. The results display that ADSCs exhibit better adhesion and significantly increased viability on the Chr-loaded PCL/PEG nanofibrous mats in relative to the PCL/PEG nanofibers and tissue culture polystyrene. The greater viability of ADSCs on Chr based nanofibers was further confirmed by higher expression levels of stemness markers Sox-2, Nanog, Oct-4, and Rex-1. These findings demonstrate that Chr-loaded PCL/PEG electrospun nanofibrous mat
