    摘要: The present invention provides markers that can selectively distinguish pancreatic progenitor cells. The present invention also provides methods for distinguishing pancreatic progenitor cells by using the markers as an indicator, and reagents to be used in the methods.The present inventors successfully identified the surface marker Nephrin-like 3 (Neph3) which is specifically expressed in pancreatic progenitor cells, and isolated pancreatic progenitor cells using the marker as an indicator or such. Viable pancreatic progenitor cells can be selected by using Neph3 as an indicator without using translated products and transcripts of any foreign genes. The marker is useful in preparing and identifying pancreatic progenitor cells which are applied to regenerative medicine or such for treatment of pancreatic diseases.

    摘要: The present invention identified Lmx1a genes, which are expressed in dopaminergic neurons at all differentiation stages, from proliferating dopaminergic neuron progenitor cells before cell cycle exit to cells after cell cycle exit. Lmx1a expression in cells can be used as an indicator when selecting cells suitable for transplantation therapy for neurodegenerative diseases such as Parkinson's disease, and is useful as a marker for screening agents involved in the induction of dopaminergic neuron differentiation.
