1360 results about "Epidermal growth factor" patented technology

Human EGF is a 6-kDa protein with 53 amino acid residues and three intramolecular disulfide bonds. EGF binds to the epidermal growth factor receptor. EGF was originally described as a secreted peptide found in the submaxillary glands of mice and in human urine. EGF has since been found in many human tissues including submandibular gland (submaxillary gland) and parotid gland. Initially, human EGF was known as urogastrone.

Particulate acellular tissue matrix

A method of processing an acellular tissue matrix to give a particulate acellular tissue matrix includes: cutting sheets of dry acellular tissue matrix into strips; cryofracturing the dry acellular tissue matrix strips at cryogenic temperatures; separating the resulting particles by size at cryogenic temperatures; and freeze drying the fraction of particles desired size to remove any moisture that may have been absorbed to give a dry particulate acellular tissue matrix. Rehydration of the dry particulate acellular tissue matrix may take place just prior to use. The particulate acellular tissue may be applied to a recipient site, by way of injection, spraying, layering, packing, in-casing or combinations thereof. The particulate acellular tissue may further include growth and stimulating agents selected from epidermal growth factor, fibroblast growth factor, nerve growth factor, keratinocyte growth factor, platelet derived growth factor, vasoactive intestinal peptide, stem cell factor, bone morphogetic proteins, chondrocyte growth factor and combinations thereof. Other pharmaceutically active compounds may be combined with the rehydrated particulate material including: analgesic drugs; hemostatic drugs; antibiotic drugs; local anesthetics and the like to enhance the acceptance of the implanted particulate material. The particulate material product may also be combined with stem cells selected from mesenchymal stem cells, epidermal stem cells, cartilage stem cells, hematopoietic stem cells and combinations thereof.

Clinical-grade human mesenchymal stem cell serum-free complete medium

The invention relates to a human mesenchymal stem cell culture medium. According to the culture medium, the basal culture medium comprises the following components based on the final concentration: 1-2g / L of human serum albumin, 5-10mg / L of transferring, 2-8mg / L of fibronectin, 1-4mg / L of laminin, 50g / L of Fe(NO3)3.9H2O, 417g / L of FeSO4.7H2O, 1-3mu g / L of estradiol, 2-5mu g / L of testosterone, 1-3mu g / L of progesterone, 39.25-117.74 mu g / L of dexamethasone, 5-10mg / L of insulin, 376.36mg / L of riboflavin, 80.96-242.87mg / L of coenzyme A, 4.41-6.17mg / L of butanediamine, 1-2mg / L of taurine, 0.61-1.85mg / L of aminoethanol, 8.81-26.42mg / L of pyruvic acid, 3.78-7.56mu g / L of sodium selenate, 292.3-584.6mg / L of L-glutamine, 2-8mu g / L of vascular endothelial growth factor, 4-10mu g / L of epidermal growth factor, 4-10mu g / L of basic fibroblast growth factor, 1-5mu g / L of leukaemia inhibitory factor, 1-5mu g / L of insulin-like growth factor-I and 2-8mu g / L of stem cell factor. The culture medium does not contain the animal serum, the potential animal endogenous endotoxin or virus of the animal serum is eliminated, and the culture medium is conveniently applied to clinics.

Complete medium with low serum concentration for cultivating mesenchymal stem cells and method for cultivating mesenchymal stem cells using same

The invention discloses a complete medium with low serum concentration for cultivating mesenchymal stem cells and a method for cultivating the mesenchymal stem cells using same. The complete medium comprises a cell basic medium, fetal calf serum with final concentration of 1-100 mul / ml, an epidermal growth factor with final concentration of 1-100 ng / ml, and a basic fibroblast growth factor with final concentration of 1-100 ng / ml. The complete medium with low serum concentration successfully reaches equal or even better function of promoting cell proliferation than a culture reagent with high serum concentration. The cultured cells have the typical biological characteristics of mesenchymal stem cells, and can also express an omnipotent mark of the embryonic stem cell and high express the idiosyncratic mark of the neuron under the condition of in vitro inducement. And the difference between the cell batches is little, the cost is low and the security is good. Compared with the prior cultivating method, the method has advantages of simple operation, low probability of pollution and high success ratio of cultivating cells.

Acne-removing scar-lightening mask solution, manufacturing method and acne-removing scar-lightening mask

The invention discloses an acne-removing scar-lightening mask solution which is prepared from the following components in percentage by weight: 0.01-1% of high-molecular humectant, 0.01-0.2% of disodium edetate, 0.01-0.5% of thickener, 5-25% of witch hazel extract, 0.01-2.0% of conditioner, 0.01-5% of desensitizer, 1-10% of low-molecular humectant, 1-8% of plant acne-removing agent, 0.1-0.5% of preservative, 0.01-0.5% of mung bean extract, 0.01-5% of epidermal growth factor and the balance of deionized water. The manufacturing method of the acne-removing scar-lightening mask solution is simple. Under the synergistic actions of the plant acne-removing agent and mung bean extract in combination with the epidermal growth factor and witch hazel extract, the mask solution has the quick effects of acne removal, itching relief and sterilization, and can restore the damaged skin and lighten the acne marks and scars while removing the acnes, thereby improving the skin from inside to outside and restoring the smooth, delicate and healthy skin.
