摘要： SUSD2 protein is used as a marker in identification, selection or separation of pancreatic internal secretion precursor cells and/or newborn pancreatic internal secretion cells; and a use of an mRNA, for encoding the SUSD2 protein, of a precursor protein as the marker in identification of the pancreatic internal secretion precursor cells and/or the newborn pancreatic internal secretion cells. Analysis of gene expression of pancreatic endoderm cells sourced by induced directional differentiation of human pluripotent stem cells finds the enrichment expression of a SUSD2 gene in the pancreatic internal secretion precursor cells and the newborn pancreatic internal secretion cells. A protein encoded by the SUSD2 gene is a receptor protein on cell membranes. Using the protein as the marker, the identification, the selection or the separation of the pancreatic internal secretion precursor cells and the newborn pancreatic internal secretion cells can be conducted.
