Description
Technical Field

Background
The scar is a local symptom which is left by fibrous tissue replacement repair and affects the appearance and the function, and the damage of physical, biological, chemical and other factors acts on the skin soft tissue of a human body, so that the skin soft tissue is seriously damaged and cannot be completely and normally repaired. The scars bring great physical and mental pain to the patient, especially scars left after burns, scalds and severe trauma. The period of scar hyperplasia is almost overwhelming for the patient for several years. The later atrophy period leads the patient to be completely non-planar and dysfunctional, and causes the patient to be extremely severely double-disturbance of the body and the heart.
Fibrous stem cell factor gels are currently used for repair and treatment of scar tissue. Such gels can promote the regeneration and repair process of the wound area by providing a suitable growth environment and active ingredients.
Fibroblasts are the main connective tissue cells existing in various tissues of the human body, and have important biological functions including synthesis of collagen, extracellular matrix, and the like. Stem cell factor is a special protein secreted by stem cells and can regulate cell proliferation, differentiation and function. By adding fibroblast and stem cell factor into gel, it can provide the growth factor and signal molecule needed by wound area, promote cell proliferation and tissue repair.
However, the existing fibroblast stem cell gel has the following defects: although fibroblast stem cell factor gel can promote repair of scar tissue, its efficacy may vary from individual to individual. For some severe scars, normal skin function may not be fully restored using this technique alone. Evidence of lack of long term validity: although fibroblast stem cell factor gels have shown some scar repair in laboratory and preliminary clinical studies, there is insufficient evidence for their long-term effectiveness. There is also a need for deep long-term follow-up studies to evaluate the persistence of their therapeutic effects. Lack of unified standards and specifications: in the use of fibroblast stem cell factor gel scar repairing technology, unified standards and specifications are lacking, so that great variability exists in clinical application of the technology. This presents some confusion to the clinician and patient.

Experimental example 2
Single wound area at 1cm was recruited 2 And 10cm 2 1 volunteer with scar on body, and the patient has good health status and no other systemic diseases, and signs informed consent before the test.
The body has a length of 1cm 2 Volunteers of scars, scars were smeared with scars gels containing epidermal stem cell factor prepared by the experimental group. The scar repairing gel is uniformly smeared on the scar every day, and the scar repairing gel is used once in the morning and at the evening, no other products are used in the morning and evening, and after the scar repairing gel is normally used for 10 days, the scar is obviously lightened and has a color similar to that of surrounding skin as shown in figure 4.
The body has a length of 10cm 2 Volunteers of scars, scars were smeared with scars gels containing epidermal stem cell factor prepared by the experimental group. The scar repairing gel is uniformly smeared on the scar every day, and the scar repairing gel is used once in the morning and at the evening, no other products are used in the morning and evening, and after the scar repairing gel is normally used for two months, as shown in figure 5, the scar is obviously lighter and has a color similar to that of surrounding skin.
It follows that the gel of the invention is able to promote scar repair with a lower risk. The gel of the invention has strong versatility and has anti-inflammatory and immunoregulatory effects. The invention utilizes the multi-factor secretion extraction mixed solution to repair the scar. The cells of the invention are used for a plurality of times, thereby reducing the cost. The invention can provide better help for scar repair research.
While the invention has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the invention and are intended to be within the scope of the invention as claimed.
