Immortalized Bovine Satellite Cells for Cultured Meat Applications

Area of Science:

• Biotechnology
• Cell Biology
• Food Science

Background:

• Scaling cultured meat production requires efficient in vitro expansion of muscle cells.
• Primary cells face limitations like senescence and variability, hindering large-scale biomass generation.

Purpose of the Study:

• To develop genetically immortalized bovine satellite cells (iBSCs) for enhanced cultured meat production.
• To overcome limitations of primary cells for consistent and rapid cell expansion.

Main Methods:

• Genetically immortalized bovine satellite cells (iBSCs) were created by constitutively expressing bovine Telomerase reverse transcriptase (TERT) and Cyclin-dependent kinase 4 (CDK4).
• Cellular growth, senescence escape, and myogenic differentiation capacity were assessed.

Main Results:

• The developed iBSCs demonstrated over 120 doublings, indicating rapid expansion potential.
• These cells retained their ability to undergo myogenic differentiation, crucial for muscle tissue formation.
• The immortalized cells provide a consistent and robust cell population for biomass production.

Conclusions:

• Genetically immortalized bovine satellite cells (iBSCs) represent a significant advancement for cultured meat technology.
• iBSCs offer a reliable and scalable cell source, overcoming key challenges in cultured meat development.
• This research provides a valuable tool for accelerating the cultured meat industry.
