lactocyte
lactocyte
"A milk-producing glandular epithelial cell that is part of a mammary gland alveolus and differentiates from a luminal adaptive secretory precursor cell during secretory differentiation (also termed lactogenesis I). Following secretory activation (also termed lactogenesis II), a lactocyte is involved in the synthesis and/or transport of milk constituents including proteins, oligosaccharides, lactose, micronutrients, fat, hormones, immunoglobulins, and cytokines into the lumen of the lactating mammary gland."
