The invention relates to a stem cell bioactive nano-vesicle with efficient inflammation regulation and tissue repair effects, the average particle size of the nano-vesicle is 100-350nm, the polydispersity index (PDI) is 0.05-0.40, and the expression rate of phosphatidylserine (PS) on the surface of the nano-vesicle is greater than 40%. According to the preparation method, stem cells are subjected to apoptosis induction, and then a programmed serial extrusion process is adopted to prepare the nano-vesicles. The nano vesicles are moderate in particle size, uniform in distribution and high in production efficiency, the preparation process is easy to operate, the quality is stable and controllable, and the nano vesicles have excellent technical effects in the aspects of repair and regeneration of inflammation injury type tissues and organs.

The application provides a recombinant human K14 keratin and a preparation method and application thereof, and relates to genetic engineering technology. The recombinant human K14 keratin has cell adhesion activity and comprises at least x continuous amino acid residues in SEQ ID NO. 10; wherein, 472 > x > 36. The recombinant human K14 keratin has higher cell proliferation activity and skin repair function, has low production cost, and is suitable for large-scale production.

The invention relates to the technical field of infant skin moistening oil, and discloses infant skin moistening oil containing olive refined components, which comprises the following components: a phase A I, a phase B I, a phase A II, a phase B II and a phase B III. The preparation method of the infant skin-moistening oil containing the olive extracted component comprises the following steps of: adding the olive extracted component into the infant skin-moistening oil. Compared with the prior art, the skin moistening oil for infants and children has the advantages that the obtained skin moistening oil for infants and children is mild and non-irritant, has a very good moisturizing effect and certain bacteriostatic and anti-allergic effects, can relieve skin and reduce skin allergy conditions, can also prevent and treat eczema and dermatitis, is safe, mild and non-irritant, and has a good application prospect. The skin care product is especially suitable for being used as a skin care product for children and infants, has a good function of repairing damaged and sensitive skin, and is safer and more stable due to the fact that the skin care product contains pure natural plant components.

This invention belongs to the field of microbial technology, specifically disclosing a probiotic microcapsule, its preparation method, and its application in the preparation of products for preventing and treating calf diarrhea. Targeting the digestive physiology and pathogenesis of diarrhea in calves, this invention prepares A-type and B-type microcapsules with different probiotics, targeting different segments of the digestive tract for release, and then coats them together to obtain probiotic microcapsules. Through the combination of microalgae, strains, and formulation design, the probiotic microcapsules prepared by this invention not only exhibit excellent acid resistance and superior small intestinal epithelial barrier repair function, but also can deliver probiotics in a gastrointestinal zone with targeted delivery, effectively inhibiting the proliferation of pathogenic bacteria and thus better preventing and treating calf diarrhea.
