Abstract

The invention discloses a culture medium good in hematopoietic stem cell adherence. The culture medium comprises an RPMI-1640 culture medium, 5-8mug/L of hyaluronic acid, 3.2-3.8g/L of trehalose, 20-30mg/L of ethanolamine, 0.7-1g/L of potassium bicarbonate, 6-9mug/L of methionine chelate selenium, 2-5mug/L of beta-mercaptoethanol, 2-3g/L of transferrin, 200-260mg/L of stem cell factors, 50-80mg/L of placental growth factors, 30-50mg/L of fibroblast growth factors, 80-100mg/L of glutathione, 80-110mg/L of vitamins and 180-220mg/L of plant extracts. The culture medium is good in cell adherence, rapid in proliferation rate, pathogen-resistant microbial action of the cultural medium is improved, components of animal origin are avoided, residues or pollution cannot be caused, and cost of the culture medium is lowered.

Description

technical field [0001] The invention relates to the technical field of stem cell culture medium, in particular to a culture medium with good adherence of hematopoietic stem cells. Background technique [0002] The stem cell culture medium in the prior art often uses fetal bovine serum. Due to the use of animal-derived fetal bovine serum, the stem cell culture medium is mixed with non-human substances, resulting in residue or pollution, and the existing stem cell culture medium has cell stickers. The wall is poor, and the cell proliferation rate is not ideal. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a medium with good adherence of hematopoietic stem cells, which has good cell adherence, fast proliferation, improves the anti-pathogenic microorganism effect of the medium, and has no animal-derived components at the same time. It will not cause residue or pollution, reducing the co...
