Physical optimization of cell proliferation and differentiation using spinner flask and microcarriers

Area of Science:

• Cellular agriculture
• Biotechnology
• Food science

Background:

• Traditional animal agriculture faces limitations including environmental impact and resource inefficiency.
• Cell-based meat offers a sustainable alternative but requires scalable production methods.
• Large-scale cell culture technology is a critical bottleneck for cell-based meat industrialization.

Purpose of the Study:

• To optimize parameters for large-scale 3D cell culture in spinner flasks.
• To investigate methods for promoting myogenesis and creating tissue-like muscle fibers.
• To establish foundational knowledge for industrialized cell-based meat manufacturing.

Main Methods:

• Utilized a single-factor variable method to optimize culture conditions.
• Investigated Cytodex1 microcarrier pretreatment (UV, collagen) and spinner flask parameters (speed, resting time).
• Developed two culture systems: one for cell expansion and one for myogenesis promotion.

Main Results:

• Identified optimal parameters for large-scale 3D cell culture in spinner flasks.
• Demonstrated the potential of collagen and 3D culture to promote myogenesis.
• Successfully prepared systems for large-scale cell expansion and myogenesis differentiation.

Conclusions:

• Optimized large-scale cell culture parameters are crucial for cell-based meat production.
• The study provides a theoretical and practical foundation for industrial cell-based meat manufacturing.
• This research offers insights into in vitro myoblast culture and potential cell therapies for muscular dystrophy.
