  • Patent number: 11987608
    Abstract: Provided is a composition for accelerating cell proliferation, including an erythropoietin-derived peptide as an active ingredient. Due to having a simpler structure than that of the existing natural human erythropoietin, the composition easily passes through the tissue-blood barrier, exhibits excellent cell protective activity, does not cause side effects of cell proliferation, and improves a hematopoietic function. Accordingly, the composition is used in the treatment or prevention of an anemic disorder.
