The invention relates to a gel preparation for maintaining the activity of cryopreserved cells and a stem cell gel preparation containing stem cells. Including the following components in mass percentage: 1-3% sodium alginate, 1-5% dimethyl sulfoxide, 1-5% propylene glycol, 1-5% beneficial polyphenols, 2%-10% dextran, 1‑5% human albumin, supplemented with water or phosphate solution. The gel preparation has good biocompatibility, is easy to operate, can maintain the high activity of cells, and can be directly stored at low temperature without the need for traditional liquid nitrogen cryopreservation. The recovered cell gel preparation can still maintain the high activity of cells And cell stemness, can be used as a treatment for skin damage or mucosal damage. |
