full_question: In one human microbiome, the onset of this process is characterized by high levels of Leuconostoc that are gradually replaced by Veillonella in later stages. The tumoricidal albumin-derived protein complex HAMLET promotes apoptosis during the involution that follows the cessation of this process. Cap cells in TEBs can differentiate into a group of cells which produces contractile force during this process called myoepithelial cells. This process canonically involves one paracellular and four transcellular pathways in alveolar cells. Bile salt-stimulated lipase is produced during this process, which initially generates a substance rich in transferrin and secretory IgA to provide passive immunity. This process occurs after parturition in an estrous cycle, and it causes the release of colostrum within the first few days. Micellar casein granules are synthesized during this process, which is stimulated via the "letdown reflex" by oxytocin and prolactin. For 10 points, name this process by which mothers produce nutrition for newborns
