PEPTIDE INHIBITING DIFFERENTIATION OF HEMATOPOIETIC STEM CELLS OR HEMATOPOIETIC PRECURSOR CELLS AND USE OF SAME

摘要

Disclosed is a novel peptide effectively usable in constructing or proliferating in vitro tissue-specific stem cells or tissue-specific precursor cells. The peptide, which is a peptide having an amino acid sequence comprising the amino acid residues represented by SEQ ID NO:1 or an analog of the same, is characterized by having at least one of the following effects: (1) an effect of inhibiting the differentiation of hematopoietic stem cells or hematopoietic precursor cells into myelocytic cells; (2) an effect of promoting the amplification of mesenchymal stem cells; and (3) an effect of inducing hematopoietic stem cells from pluripotent cells.
