The ultrastructural architecture of colostral cells of mothers of pre- and full-term infants is described. The polymorphonuclears were engaged in vivid phagocytosis of fat droplets. Similar findings were observed on the macrophages. The lymphocytes appeared normal in size and ultrastructure. A small number of eosinophils and basophils were also detected. The number of colostral cells was higher in the colostrum of mothers of preterm newborns. The number of the cells in the colostrum in mothers of both groups decreased with advancement of lactation.
