Bovine Placentome-Derived Extracellular Matrix: A Sustainable 3D Scaffold for Cultivated Meat

Area of Science:

• Cellular agriculture
• Tissue engineering
• Biomaterials science

Background:

• Traditional meat production poses environmental, ethical, and health concerns.
• Cultivated meat offers a sustainable alternative by using cellular agriculture and tissue engineering.
• Existing scaffolds often lack crucial biological cues for optimal cell growth.

Purpose of the Study:

• To develop and evaluate a novel scaffold for cultivated meat production.
• To investigate the potential of bovine placentome-derived extracellular matrix (ECM) as a scaffold material.
• To assess the ability of the scaffold to support myoblast growth and differentiation into muscle-like tissue.

Main Methods:

• Decellularization of bovine placental tissue to isolate collagen and ECM.
• Preparation of porous scaffolds using dehydrothermal (DHT) crosslinking.
• Culture of bovine myoblasts on ECM scaffolds for 50 days.
• Analysis of cell growth, differentiation, and construct properties.

Main Results:

• Bovine placentome-derived ECM scaffolds demonstrated superior compatibility and stability compared to collagen scaffolds.
• Cultured myoblasts formed muscle tissue-like constructs with high cellularity and myogenic differentiation.
• The resulting cultivated meat constructs were cookable and retained integrity during grilling/frying.

Conclusions:

• Bovine placentome-derived ECM is a promising, biologically functional scaffold for cultivated meat production.
• This approach offers a sustainable method for creating edible, muscle-like meat constructs.
• The study pioneers the use of placentome ECM for developing innovative cultivated meat products.
