Development of a skeletal muscle sheet with direct reprogramming-induced myoblasts on a nanogel-cross-linked porous freeze-dried gel scaffold in a mouse gastroschisis model
Topic overview
Researchers developed a novel skeletal muscle sheet using directly reprogrammed myoblasts on a nanogel scaffold to treat gastroschisis in a mouse model. The nanogel-based approach showed superior muscle cell differentiation compared to traditional Matrigel, with cells forming multinucleated muscle fibers expressing key muscle markers. This technique offers potential for autologous tissue-based reconstruction of abdominal wall defects in congenital conditions.
Key takeaways
- Direct reprogramming of fibroblasts into myoblasts (dMBs) via MYOD1/MYCL transfection enables autologous skeletal muscle regeneration.
- NanoClip-FD gel scaffold outperformed Matrigel, producing multinucleated muscle cells expressing desmin and myogenin at 14 days.
- Porous nanogel structure facilitates oxygen/nutrient delivery, critical for cell differentiation and engraftment in tissue engineering.
- Biosheet-based skeletal muscle constructs show promise for gastroschisis repair using patient-derived cells and tissues.
- Combining direct cellular reprogramming with nanogel scaffolds offers a novel approach to regenerative abdominal wall reconstruction.
