Abstract
Description
[Technical field]
[0001] The present invention relates to the field of biomedical technology, specifically to hair follicle repair protein compositions and methods for making and using same. [Background technology]
[0002] A large amount of hair is an important indicator of body health and hair health. Hair follicle health is the basis of hair health. The key to maintaining hair follicle health is to activate the follicular stromal cells in the scalp system. Hair follicles undergo a cyclic growth cycle of anagen, catagen, and telogen. The cyclic changes of hair follicles are closely related to the cyclic division, proliferation, differentiation, etc. of follicular stromal cells. Highly active follicular stromal cells continuously release large amounts of follicular stromal cell growth factors to promote the benign cycle of hair follicle cells to repair themselves, grow, divide, and grow hair.
[0003] Modern people, influenced by busy lifestyles, work stress, environmental pollution and other factors, suffer from hair breakage, premature aging, severe hair loss, hair regeneration disorder and other problems, which seriously affect personal image and even lead to psychological disorders. According to survey data from the National Health Commission of China, there are more than 260 million people suffering from hair loss in China, with male hair loss accounting for approximately 63%, mainly androgen-induced hair loss. The trend of hair loss occurring at a younger age has become evident, with 60% of people experiencing hair loss symptoms around the age of 25, and the proportion of people suffering from hair loss after the 90s (the Chinese term for young people born between 1990 and 2000) is as high as 84%, with severe hair loss as high as 46.7%.
[0004] Hair diseases include physiological or pathological symptoms such as hypotrichosis, hypertrichosis, abnormal hair distribution, abnormal hair density, abnormal hair diameter, abnormal hair pigmentation, abnormal hair shaft, etc. Hair loss includes physiological hair loss and pathological hair loss. Physiological hair loss includes natural hair loss, seasonal hair loss, infantile hair loss, senile hair loss, and postpartum hair loss. Pathological hair loss includes non-scarring hair loss and cicatricial hair loss. Non-scarring hair loss includes androgenic alopecia (ratio is about 95%), alopecia areata (ratio is about 4%), syphilitic alopecia, trichotillomania, telogen effluvium, anagen effluvium, traction alopecia, physical alopecia, alopecia folliculitis, perifolliculitis capitis abscedens et suffodiens, congenital hypotrichosis, etc. When the pathogenic factor of non-scarring hair loss is removed, hair will grow again. Cicatricial alopecia is caused by the permanent destruction of hair follicles, resulting in permanent hair loss, and causes include trauma, infection, inflammatory skin diseases (e.g., discoid lupus erythematosus, hairy lichen planus, etc.), scalp lichen planus, scalp discoid lupus erythematosus, radioactive alopecia, female fibrous alopecia, scalp burns, etc.
[0005] The amount of hair in patients with pathological hair loss is obviously reduced due to abnormal hair loss and excessive shedding. Common causes of hair loss include excess male hormones, heredity, excessive stress, pregnancy, diseases, drugs, injuries, etc. Diseases such as autoimmune diseases, thyroid diseases, lupus erythematosus, diabetes, iron deficiency, eating disorders, and anemia cause changes in the body's hormone levels, which exacerbate hair loss. Antitumor drugs, anticoagulants, antihypertensive drugs, contraceptives, burns, various injuries, X-ray radiation, etc. can cause temporary hair loss.
[0006] Seborrheic alopecia (androgenic alopecia, AGA) is a hair disease whose main symptoms are excessive oil leakage from the scalp, causing hair to become gradually thinner, softer, and less abundant, and may be accompanied by scalp itching, dandruff, and itching. It is a progressive hair follicle disorder that involves genetic factors and is dependent on the action of male hormones. The total number of AGA patients in China exceeds 100 million, and the prevalence rate is higher in men (20.2%) than in women (5.1%).
[0007] Cells are the basic unit of life activity and the basis of the health of living organisms. When the redox balance of living organisms is destroyed, it will cause the interruption of redox signaling and control, induce oxidative stress disorders, and induce various diseases. Research has already shown that factors such as the number and activity of hair follicle stem cells and the regeneration ability of hair follicles are directly related to hair loss. The decrease in the number and activity of hair follicle stem cells weakens the differentiation ability of hair follicle cells, affecting the hair regeneration cycle, which causes hair follicles to be blocked and permanent hair loss to occur. The main methods for treating hair loss include hair washing care, drug treatment, laser hair growth, hair transplantation, etc. Hair washing care mainly stimulates the scalp with topical products such as hair growth liquid or hair growth agent to promote blood circulation in the scalp, promote blood supply to the head, nutrition of the head, and hair growth, but has the disadvantages of poor hair growth and hair loss prevention, and is ineffective against damaged hair follicles and dormant hair follicles. Drug treatments include oral medications (e.g. finasteride, spironolactone, VB2, VB6, tanshinone capsules, glycyrrhizin combination tablets, white peony sugar capsules, etc.) and topical medications (e.g. minoxidil solution, halcinonide solution, selenium sulfide, etc.), but they have shortcomings such as poor hair loss treatment effects, significant side effects, and drug dependency. Laser hair growth uses low-energy laser irradiation with a wavelength of 670 nm to enhance cell activity, promote blood microcirculation, increase blood supply and nutrition to the head, promote the absorption of nutrients in hair, improve the activity of hair matrix cells and hair follicle stem cells, accelerate protein synthesis, and activate hair follicles, but has shortcomings such as slow hair growth and high cost. Hair transplantation requires surgery, in which hair follicles from the patient's back and both sides of the head are selected as the hair source, the harvested hair follicles are separated into single or multiple hair follicles, and then the single or multiple hair follicles are transplanted to the bald area that needs to be transplanted through precise microsurgery, so that the newly transplanted single or multiple hair follicles survive and grow in the new hair transplantation area, and further restore the local hair distribution and distribution density.Although hair transplantation technology can solve the problem of completely blocked hair follicles, it is limited by the limited transplantable sites and hair follicle resources, and hair transplantation surgery is painful, has the risk of infection, the survival rate of newly transplanted hair follicles is not guaranteed, the problem of repairing damaged hair follicles cannot be solved, scars remain at the transplantation surgery site, which affects the aesthetic appearance, and is expensive, etc. Therefore, in clinical practice, there is an urgent need for a safe and effective hair growth composition with better hair growth and hair loss prevention effects, reliable treatment effects, and high efficacy.
[0008] When cells and microorganisms are subjected to stress induction by external stimuli and exogenous stress substances (including cold, heat, acid, alkali, electric current, radiation, chemical substances, etc.), the cells and microorganisms are induced to produce stress proteins through a stress response. Literature 1 (New limonophyllines AC from the stem of Atalantia monophylla and cytotoxicity against cholangiocarcinoma and HepG2 cell lines, Arch. Pharm. Res. (2018) 41:431-437) discloses that compounds 1-16 prepared by extraction from a Rutaceae plant (Atalantia monophylla) have activity to inhibit the proliferation of tumor cells, etc.
[0009] Mesenchymal stem cells (MSCs) have the ability to self-renew and differentiate in multiple directions. They are widely distributed in bone marrow, fat, synovium, dental pulp, amniotic fluid, placenta, umbilical cord, embryo, umbilical cord blood, amniotic membrane, peripheral blood, muscle, urine and other tissues. They have characteristics such as wide supply source, no need for matching, low infection rate, strong differentiation ability, strong proliferation ability and easy collection. They can produce activating factors such as stem cell factor (SCF), nerve growth factor (NGF), interleukin-6 (IL-6), interleukin-7 (IL-7), tumor necrosis factor (TNF), interferon (IFN) and other activating factors. They are involved in the regulation of processes such as cell proliferation, apoptosis, cell differentiation, antiviral and immune maturation, and can be used for immune regulation, tissue repair and treatment of diseases such as acute lung injury, severe pneumonia and acute respiratory distress syndrome. However, MSCs products require refrigeration during production, storage, transportation, and use, and their cell activity can only be maintained for 12 hours or less, limiting their therapeutic use. Therefore, there is a need to develop a safe and effective skin repair drug to meet clinical needs. Summary of the Invention [Problem to be solved by the invention]
