Abstract: A recombinant humanized collagen type I alpha-1 (rhCol1A1), and an expression vector and use thereof are provided, belonging to the technical field of bioengineering. The rhCol1A1 has an amino acid sequence of SEQ ID NO: 1. This aim is to solve the problem of difficulty in expressing soluble full-length humanized collagen in Escherichia coli prokaryotic expression systems, and differences between the recombinant collagen and humanized collagen in yeast expression systems. It is proposed that the rhCol1A1 chain is expressed in Expi293F human embryonic kidney cells, and the protein expression level is increased using a fusion expression plasmid, enabling the expression of full-length humanized collagen type I alpha 1 chain. Activity studies have shown that the expressed rhCol1A1 exhibits a desirable activity in promoting cell migration, and may be widely used in the fields of biomedicine, tissue engineering, skin care, and food.

Abstract: Provided are a recombinant collagen, an expression method and use thereof. In the present disclosure, the recombinant collagen is expressed by a human embryonic kidney cell Expi293F at a high protein expression level, thereby realizing the expression of a large-molecular-weight recombinant collagen. Activity studies have showed that the expressed recombinant collagen has desirable activity in promoting cell migration, while the recombinant collagen III+I with a fusion tag shows high stability at 4° C. In addition, cell activity studies have shown that the recombinant type III collagen expressed by human cells has better activity in promoting the cell migration than that of a commercially available type III collagen. These results indicate that the human cell expression system is conducive to the expression of highly active and large-molecular-weight recombinant collagen.
