Establishment of chicken muscle and adipogenic cell cultures for cultivated meat production
Research Overview
Cultured meat aims to reproduce the sensory and nutritional qualities of conventional meat by growing structured muscle tissue in culture. This study cultured chicken embryonic and muscle-derived mesenchymal stem cells to derive both muscle and fat, optimizing differentiation conditions and how the two integrate.
Monolayer and 3D microcarrier-based cultures produced muscle fibers and adipocytes while preserving the extracellular matrix needed for tissue cohesion. Pluripotency and myogenic markers (cOCT4, cMYOD, cMYH1E) tracked differentiation; myoblast maturation into myotubes showed a 35% drop in cPAX7 and a 67% rise in cMYMK, confirming lineage commitment.
Key Discoveries
- Chicken MSCs differentiated into both muscle fibers and adipocytes in monolayer and 3D microcarrier culture
- ECM integrity maintained to support tissue cohesion
- Myotube maturation confirmed by cPAX7 down 35% and cMYMK up 67%
