No, Shen Dao, a maker of Jida, is a low-molecular-weight polypeptide bioactive substance jointly developed by the Institute of Semiconductors of Chinese Academy of Sciences and Jinan University. It can promote cell proliferation, differentiation and repair, promote wound healing, prevent angiogenesis and reduce inflammation, so Shen Dao, a maker of Jida, is not a growth factor. Growth factors are a kind of organic substances that are necessary to regulate the normal growth and metabolism of microorganisms, but cannot be synthesized by simple carbon and nitrogen sources. In addition to vitamins, growth factors in a broad sense include bases, purines, pyrimidines, biotin and nicotinic acid, and sometimes amino acids required by amino acid auxotrophic mutants, while growth factors in a narrow sense generally only refer to vitamins.
