Collagen-tussah silk fibroin hybrid scaffolds loaded with bone mesenchymal stem cells promote skin wound repair in rats.

This study demonstrates the efficacy of collagen/tussah silk fibroin (Col/TSF) hybrid scaffolds loaded with bone mesenchymal stem cells (BMSCs) in skin repair. Collagen (Col) and tussah silk fibroin (TSF) were extracted from bovine tendons and tussah cocoons, respectively. Col/TSF scaffolds were obtained using a freeze-drying method and were characterised using fourier transform infrared spectroscopy, scanning electron microscopy, porosity, water retention, thermal stability, and biocompatibility.

Development of a HPLC Method for the Quantitative Determination of Capsaicin in Collagen Sponge.

Controlling the concentration of drugs in pharmaceutical products is essential to patient's safety. In this study, a simple and sensitive HPLC method is developed to quantitatively analyze capsaicin in collagen sponge. The capsaicin from sponge was extracted for 30 min with ultrasonic wave extraction technique and methanol was used as solvent.
