The present study explores the differentiation of myoblasts in bioengineered 3D composite scaffolds containing keratin and gelatin. Based on the composition and rheological properties three different scaffolds namely HM1, HM2 and HM3 were prepared, characterized and employed for the present study. The scaffolds were then subjected to CC myoblasts differentiation under in vitro conditions as per the standard protocols. Results reveal a wide variation in the elastic modulus, water uptake and degradation rate of the scaffolds significantly impact the myogenesis processes. Composite scaffolds HM2 and HM3 ease the myogenesis compared to HM1, wherein, results in nil myogenesis. Among HM2 and HM3, accelerated myogenesis and the significant expression of myogenin mRNA levels along with extensive myotube development were observed in the HM3 scaffold. In conclusion, scaffolds modulus play a vital role in myogenesis and the observations of the present study provide a possible strategy for better skeletal muscle regeneration using composite scaffolds.

Mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) have emerged as a promising therapeutic strategy for spinal cord injury (SCI). These nanosized vesicles possess unique properties such as low immunogenicity and the ability to cross biological barriers, making them ideal carriers for delivering bioactive molecules to injured tissues. MSC-EVs have been demonstrated to exert multiple beneficial effects in SCI, including reducing inflammation, promoting neuroprotection, and enhancing axonal regeneration.

Liver transplantation is the only curative option for end-stage liver disease and is necessary for an increasing number of patients with advanced primary or secondary liver cancer. Many patient groups can benefit from this treatment, however the shortage of liver grafts remains an unsolved problem. Liver bioengineering offers a promising method for expanding the donor pool through the production of acellular scaffolds that can be seeded with recipient cells.
