Basic Fibroblast Growth Factor (bFGF) is a member of the FGF family of mitogenic peptides which is comprised of at least 23 proteins. FGF signaling factors play a central role during prenatal development and postnatal growth and regeneration of a variety of tissues, by promoting cellular proliferation and differentiation. It was originally named bFGF based upon its chemical properties and to distinguish it from acidic fibroblast growth factor.

Keratinocyte Growth Factor-2 (KGF-2) was originally identified from rat embryos by homology-based polymerase chain reaction. Human and mouse KGF-2 were subsequently cloned. The human KGF-2 cDNA encodes a 208 amino acid residue protein with a hydrophobic amino-terminal signal peptide. Human KGF-2 shares approximately 92% and 95% amino acid sequence identity with mouse and rat KGF-2, respectively. Among the FGF family members, KGF-2 is most closely related to FGF-7. KGF-2 transcripts has been shown to be most abundant in the embryo and adult lungs. Recombinant KGF-2 preparations have been shown to be mitogenic for epithelial and epidermal cells but not fibroblasts. Based on its in vitro biological activities and in vivo expression pattern, KGF-2 has been proposed to play unique roles in the brain, in lung development, wound healing and limb bud formation.

Name: EGF,Recombinant human epidermal growth factor (rhEGF) CAS No.: 62253-63-8 Grade: cosmetic INCI Name: Human Oligopeptide-1 Source: E. coli Endotoxin level: less than 0.1 ng per μg (1EU/ug). 2.Introduction: EGF secreted by each of us, when we were in child times the secretion is the highest, and then it decreased with age increases. Particularly, After 22 years of age, reduced secretion was more pronounced. When we use cosmetics containing EGF, absorbed through the skin, added EGF of our skin exogenously, so that it can make our skin to restore the young state. We use E.coli by genetic engineering expressed, produced high purity EGF by biological fermentation. It was named Recombinant human epidermal growth factor (rhEGF). rhEGF have same structure with Human epidermal growth factor (EGF), it is a 6.2kDa protein.EGF stimulates the proliferation and differentiation of epithelial cells from skin, the cornea, lung and tracheal tissue and the gastrointestinal tract. EGF also promotes the proliferation of fibroblasts and embryonic cells. Thus, EGF plays an important role in wound healing and organogenesis. EGF is a highly efficient cell division factor with many other biological effects, which mainly includes: 1. stimulating the growth and proliferation of skin, cornea and tracheal epithelium tissue in vivo. 2. Accelerating the healing process of epidermis damage on skin, cornea, etc. 3. Repressing the gastric acid excretion. 4. Accelerating the proliferation of epithelial cells in human and animals. 5. Facilitating the biosynthesis of protein, RNA, DNA as well as metabolic activity in epidermal cells. 3.Usage First of all, put the EGF dissolved in distilled water. Wait the temperature of cosmetic cream decreased to below 40 degrees Celsius, then put the dissolved solution into the cream, stir the cream to full blending them.

INCI name: metallothionein, metallothioneins Purity:70%,80%,95% , Molecular:6500 Grade: cosmetic Appearance:white powder 2.Functions: Metallothionein( , MT) can eliminate free radicals and prevent aging; to lift heavy metal toxicity; involved in the metabolism of trace elements in the human body; enhance immune function and has the ability to adapt to a variety of adverse state; prevent cancer cells; resistance to apoptosisand so on. 3.Introduction: Metallot , hionein (MT) is a family of cysteine-rich, low molecular weight (MW ranging from 500 to 14000 Da) proteins. They are localized to the membrane of the Golgi apparatus. MTs have the capacity to bind both physiological (such as zinc, copper, selenium) and xenobiotic (such as cadmium, mercury, silver, arsenic) heavy metals through the thiol group of its cysteine residues, which represent nearly 30% of its constituent amino acid residues. MT was discovered in 1957 by Vallee and Margoshe from purification of a Cd- binding protein from horse (equine) renal cortex. MTs function is not clear, but experimental data suggest MTs may provide protection against metal toxicity, be involved in regulation of physiological metals (Zn and Cu) and provide protection against oxidative stress. There are four main isoforms expressed in humans (family 1, see chart below): MT1 (subtypes A, B, E, F, G, H, L, M, X), MT2, MT3, MT4. In the human body, large quantities are synthesised primarily in the liver and kidneys. Their production is dependent on availability of the dietary minerals, as zinc, copper and selenium, and the amino acids histidine and cysteine.
