Abstract

The invention relates to biological gel for treating refractory skin damage and application of the biological gel. The biological gel is prepared from umbilical cord mesenchymal stem cells coated by biocompatible degradable gel with special stem cell culture additives, wherein the stem cell culture additives comprise umbilical cord mesenchymal stem cells, traditional Chinese medicine extracts and serum. The biological gel provided by the invention is capable of promoting normal body cell proliferation, reducing influence of common negative irritation such as anoxia and chemotherapy to normal body cells, prolonging cell growth time, promoting cell factor secretion and effectively treating refractory skin damage such as burning and scalding, and is safe and efficient, small in side effect, simple to product and low in cost.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a biological gel for treating refractory skin damage and its application. Background technique [0002] Refractory skin damage is not a disease, but a phenomenon of skin damage caused by various diseases or injuries. Common factors leading to refractory skin damage include burns, diabetes, lupus erythematosus, and psoriasis. At present, there is no perfect solution to these problems, because this kind of damage is often accompanied by complex immune disorders and tissue regeneration disorders, and a single treatment plan cannot solve all problems. However, stem cell therapy emerging in recent years is expected to solve all the problems of tissue regeneration and immune regulation. [0003] Stem cells are a kind of pluripotent cells with self-replication ability, among which mesenchymal stem cells are considered to have the most medical value. On the one hand, this kind of ...
