摘要：Human colostrum and milk represent complex biological liquids containing different immunoactive agents that change during lactation. These include immunocompetent cells like neutrophils, macrophages and lymphocytes with blood origin. Morphological characteristics of human leucocytes were assessed by the use of light microscopy, scanning electron microscopy and transmission electron microscopy. Additional characteristics of milk cells in colostrum were, investigated using membrane markers after lectins, Ag І/ІІ or MBB activation. These examinations proved lymphocytes and macrophages as potential antigen presenting cells
