23 Jul Method for preparing composite growth factor of natural cells
Abstract
This invention discloses a method for extracting natural composite growth factor. The method comprises: constructing artificial tissue/organ in vitro through tissue-engineering method, collecting the supernatant during tissue/organ culture, separating and purifying to obtain natural composite growth factor. The method can obtain large quantities of amino acids or proteins including growth factor and nutrition factor, which, after separation and purification, can be used in cell culture, cosmetics, foods and drugs.
