BIOLOGICALLY-ACTIVE FACTORS IN BOVINE-MILK AND DAIRY BY-PRODUCTS - INFLUENCE ON CELL-CULTURE

Substantial progress has been made in our knowledge of the biological properties of mammal milks. Many nutritional, biochemical, immunologic al, or other biological properties have been studied in mature or indu strially processed bovine milk as well as in human milk and colostrum. This article is a critical review of selected publications covering ( 1) the use of bovine milk or dairy byproducts (processed acid and enzy matic whey fractions) as a serum substitute for cell cultures, (2) spe cific factors in bovine milk and industrially processed milk that affe ct cell proliferation, and (3) the known functional and biological rol es of two whey proteins: beta-lactoglobulin and the PP3 component.
