Description
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 *2 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.
