Influence of extracellular matrix on bovine mammary gland progenitor cell growth and differentiation.

Objective: To examine the impact of simple versus complex extracellular matrices (ECMs) on morphologic development and differentiation of bovine mammary gland progenitor cells (BMGPCs).

Sample Population: Cultures of BMGPCs.

Procedures: BMGPCs were grown on the following extracellular matrices: collagen I, collagen IV, laminin, and a commercially available gelatinous protein mixture.

Isolation and differentiation of bovine mammary gland progenitor cell populations.

Objective: To isolate bovine mammary gland cells with stem cell characteristics.

Sample Population: Monolayers of bovine mammary gland cells.

Procedure: Mammary gland cell populations were separated by use of selected media supplements.
