Problems solved by technology

[0002] The sub-totipotent stem cell culture medium in the prior art often uses fetal bovine serum. Due to the use of animal-derived fetal bovine serum, non-human-derived substances are mixed into the stem cell culture medium, causing residue or pollution, and the existing sub-totipotent stem cell culture There are problems such as poor cell adhesion and unsatisfactory cell proliferation speed.

Description

technical field [0001] The invention relates to the technical field of stem cell culture medium, in particular to a culture medium for improving the proliferation speed of subtotipotent stem cells. Background technique [0002] The sub-totipotent stem cell culture medium in the prior art often uses fetal bovine serum. Due to the use of animal-derived fetal bovine serum, non-human-derived substances are mixed into the stem cell culture medium, causing residue or pollution, and the existing sub-totipotent stem cell culture There are problems such as poor cell adhesion and unsatisfactory cell proliferation speed. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a culture medium for increasing the proliferation speed of sub-totipotent stem cells, which has good cell adhesion and fast proliferation speed, improves the anti-pathogenic microorganism effect of the culture medium, and has no ani...
