Electrospinning is one of the fabrication method to form ultra-fine fiber in a nano-scale made of synthetic and natural extracellular matrix components for tissue-engineering applications. In this study, a nanofibrous scaffold was obtained by co-electrospinning poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and gelatin in 2,2,2-trifluoroethanol (TFE) at a ratio of 50/50. The resulting fiber diameters were in the range of 400-1,000 nm without any beads. The nanofiber surfaces were characterized by attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR), electron spectroscopy for chemical analysis (ESCA), and atomic force microscopy. It was found, from cell culture experiments, that NIH 3T3 cells on the PHBV/gelatin nanofibrous scaffold more proliferated than on the PHBV nanofibrous scaffold.

Acellular cellulose-based biomaterials hold promising potential for treating bladder injuries. However, the compromised cellular state surrounding the wound impedes the complete reconstruction of the bladder. This necessitates the development of a bio-instructive cellulose-based biomaterial that actively controls cell behavior to facilitate effective bladder regeneration.

Numerous naturally occurring biological structures have inspired the development of innovative biomaterials for a wide range of applications. Notably, the nanotopographical architectures found in natural materials have been leveraged in biomaterial design to enhance cell adhesion and proliferation and improve tissue regeneration for biomedical applications. In this study, we fabricated three-dimensional (3D) chitin-glucan micro/nanofibrous fungal-based spheres coated with collagen (type I) to mimic the native extracellular matrix (ECM) microenvironment.

Scaffolds play a crucial role in tendon healing by providing structural support, promoting cell infiltration, and guiding tissue regeneration. Polycaprolactone (PCL) has been used as a polymer in biological scaffolds for several tissue engineering studies. This study aimed to investigate the effects of curcumin-loaded PCL scaffold on Achilles tendon using a tenotomy model in rats.
