The production of lab-grown meat follows a scientific and highly controlled process that mimics natural muscle growth. Here’s a step-by-step breakdown of how it is made:

  1. Cell Extraction:
    • Scientists take a small biopsy of muscle tissue from a living animal, such as a cow, chicken, or fish.
    • The sample is carefully selected to include muscle stem cells (my satellite cells), which have the ability to multiply and differentiate into muscle fibers.
  2. Cell Cultivation in a Bioreactor:
    • The extracted cells are placed in a bioreactor, a sterile, nutrient-rich environment designed to support cell growth.
    • The cells are fed with a special growth medium containing essential nutrients such as amino acids, proteins, vitamins, and minerals.
    • To replace fetal bovine serum (FBS), which was initially used in early research, scientists are developing plant-based and synthetic alternatives to ensure ethical and scalable production.
  3. Cell Proliferation and Differentiation:
    • The muscle cells begin to proliferate (multiply rapidly), forming muscle fibers similar to those found in traditional meat.
    • Scientists use scaffolds or 3D bio printing techniques to structure the cells into a texture that closely resembles conventional meat.
    • Electrical or mechanical stimulation may be applied to encourage muscle growth and improve texture, taste, and tenderness.
  4. Harvesting and Processing:
    • Once the muscle fibers reach the desired size and structure, they are harvested and processed into various meat products.
    • Depending on the intended product, the cultivated meat may be formed into patties, nuggets, steaks, or ground meat for commercial use.
