“…Colostrum of humans and mature human milk contains 22~24 g/l and 12~13 g/l of oligosaccharides, respectively. Human milk oligosaccharides have a far more complicated structure (Newburg and Neubauer, 1995;Kunz et al, 2000) than oligosacharides in other mammalian milk; for instance, bovine milk normally contains 1-2 g/l of free saccharides other than lactose but larger amounts occur in the colostrum of cattle (Davis et al, 1983). The role of individual oligosaccharides in mammalian milk has not been fully investigated yet, particularly in the case of non-human oligosaccharides.…”

Microbial colonization of the mammalian intestine begins at birth, when from a sterile state a newborn infant is exposed to an external environment rich in various bacterial species. An important group of intestinal bacteria comprises bifidobacteria. Bifidobacteria represent major intestinal microbiota during the breast-feeding period. Animal milk contains all crucial nutrients for babies' intestinal microflora. The aim of our work was to test the influence of different mammalian milk on the growth of bifidobacteria. The growth of seven strains of bifidobacteria in human milk, the colostrum of swine, cow's milk, sheep's milk, and rabbit's milk was tested. Good growth accompanied by the production of lactic acid was observed not only in human milk, but also in the other kinds of milk in all three strains of Bifidobacterium bifidum of different origin. Human milk selectively supported the production of lactic acid of human bifidobacterial isolates, especially the Bifidobacterium bifidum species. The promotion of bifidobacteria by milk is speciesspecific. Human milk contains a key factor for the growth of specific species or strains of human-origin bifidobacteria compared to other kinds of milk. In contrast, some components (maybe lysozyme) of human milk inhibited the growth of Bifidobacterium animalis. Animal-origin strains of bifidobacteria were not able to significantly grow even in milk of animal origin, with the exception of B. animalis subsp. lactis 1,2, which slightly grew in sheep's milk.

“…The lumen of the acini contains granular and filamentous products. At days [14][15][16][17][18][19] of pregnancy or at 12-14 day of pseudopregnancy, the cytoplasm has a similar appearance but the lipid droplets are larger and more abundant and the lumen is filled with an homogenous electron-dense product [8]. In MEC from some rabbits, at this stage, a few casein micelles are detectable in the cytoplasm.…”

“…However, these variations are adapted to the physiological status of the offspring and, as long as the mammary gland is healthy, they are strictly regulated. During established lactation, the concentration of caseins gradually increases and, in most species, milk fat concentration increases in parallel [16]. In the rat, fat concentration declines in early lactation, but after the first five days following birth, once lactation is established, both fat and protein concentrations remain constant [45].…”

Milk lipid and protein traffic in mammary epithelial cells: joint and independent pathways

-In mammary epithelial cells, milk lipids and proteins are synthesised in the same compartment, the endoplasmic reticulum. Lipids, carried through the cytoplasm, associate with the apical membrane which then pinches off and releases the lipid globule. Proteins, carried through membrane compartments are released in the lumen after fusion of secretory vesicles with the apical membrane. These processes assure a relatively constant composition of milk but it is not known whether lipid and protein secretion are linked. The protein composition of the milk fat globule membrane and the stimulatory effects of prolactin and oxytocin on lipid and protein secretion suggest that these processes are coupled and co-regulated. However, it is possible to observe a dissociation between the formation and the secretion of the two constituents, during differentiation and in various experimental conditions, and this suggests that coupling is not strictly required. milk lipids / mammary epithelial cells / secretionRésumé -Transport des lipides et des protéines du lait dans les cellules épithéliales mammaires. Dans la cellule épithéliale mammaire, les lipides et les protéines du lait sont synthéti-sés dans le même compartiment, le reticulum endoplasmique. Les lipides transportés à travers le cytoplasme s'accolent à la membrane plasmique apicale qui les enveloppe avant leur sécrétion. Les protéines, transportées dans des compartiments membranaires jusqu'aux vésicules de sécrétion, sont libérées dans la lumière après fusion des vésicules avec la membrane apicale. Ces processus assurent une composition relativement constante du lait. Cependant, on ne sait pas si ces deux types de sécré-tion sont liés. La composition protéique de la membrane du globule gras et l'effet stimulant de la prolactine et de l'ocytocine sur la sécrétion des deux constituants suggèrent que synthèse et sécrétion sont liées et co-régulées. Cependant, la possibilité d'observer une dissociation entre la formation et la sécrétion des deux constituants suggère que ce couplage n'est pas obligatoire.lipides du lait / cellule épithéliale mammaire / sécrétion
