Enhanced growth and myogenic differentiation of spheroid-derived C2C12 cells
Research Overview
Physical forces can push stem cells toward a lineage by upregulating key transcription factors — and spheroid formation is one such force. This study compared parental C2C12 myoblasts with cells derived from one-day-old C2C12 spheroids, examining proliferation and myogenic gene expression in both 2D and 3D culture.
One-day-old spheroids showed more intense MyoD expression than parental cells. The spheroid-derived cells then proliferated significantly faster in a time-dependent manner and displayed significantly higher myogenic potential in both 2D and 3D — suggesting a brief spheroid stage can prime myoblasts for muscle differentiation.
Key Discoveries
- One-day-old C2C12 spheroids showed elevated MyoD expression versus parental cells
- Spheroid-derived cells proliferated significantly faster over time
- Higher myogenic potential retained in both 2D and 3D culture after the spheroid stage
