Embodiment

[0036] A preparation method for composite freeze-dried powder of multiple stem cells and a solvent, comprising the following steps:

[0037] (1) Isolation and culture of umbilical cord and placental mesenchymal stem cells

[0038] Under sterile conditions, collect healthy umbilical cord and placenta; cut the placenta to 1.5-2.5mm in GMP laboratory biosafety cabinet 3 Tissue pieces of different sizes were placed in DMEM-LG cell culture medium contained in T175 culture flasks at 37°C and 5% CO 2 Cultivated in an incubator;

[0039] Change the medium every 2-3 days until a large number of stem cells crawl out, discard the tissue pieces; when the cells are full, record it as the first generation, digest and passage with 0.28% trypsin; after the second generation, use no antibiotics DMEM-LG medium for culture; sequential subculture;

[0040] (2) Isolation and culture of adipose-derived mesenchymal stem cells

[0041] Under sterile conditions, obtain 100 mg of adipose tissue fro...

Abstract

The invention discloses a preparation method for composite freeze-dried powder with multiple stem cells and a solvent. The preparation method comprises the following steps of: utilizing a health tissue block method to culture mesenchymal stem cells of umbilical cords and placentas, then using a digestion method to culture adipose-derived stem cells, blending cell factors secreted in the culture process, finding an optimal growth concentration by a fibroblast proliferation curve test, carrying out low-temperature freezing and drying on blended culture supernatant, and preparing a suitable solvent; as a raw material of a beauty product, the solvent can be added into other beauty products in the later stage to prepare stem-cell beauty products.
