    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: In neuron transplantation therapy, in terms of safety, it is preferable to use a cell population consisting only of a desired type of cells, and to use postmitotic neurons in consideration to avoid the risk of tumorigenesis. Moreover, greater therapeutic effects would be expected through the use of earlier progenitor cells in consideration of post-transplantation viability, proper network formation ability, and such.According to the present invention, Lrp4, a gene that is specifically expressed in dopaminergic neuron proliferative progenitor cells prior to cell cycle exit, was identified. The use of Lrp4 expression in cells as an index allows for the isolation. of cells suitable for transplantation therapy of neurodegenerative diseases such as Parkinson's disease in terms of safety, survival rate, and network formation ability.

    摘要: As a result of screening for genes that are selectively expressed in fetal mouse brain region by subtraction method, the present inventors obtained a cDNA fragment encoding Corl1. The expression of Corl1 was examined by RT-PCR, in situ hybridization, and immunostaining using polyclonal antibodies. The results demonstrated that Corl1 was especially expressed at a high level of selectively in the central nervous system during embryonic stages. The expression patterns of Corl1 determined using various markers in embryonic spinal cord were compared to identify types of neurons expressing Corl1. The results revealed that Corl1 was specifically expressed in spinal cord interneurons dI4, dI5, dILA, and dILB. Accordingly, the present invention provides for discrimination between dI4 and dI6, neurons which previously could only be discriminated based on developmental location, using the expression of Corl1 as an indicator.
