摘要:
Total RNAs were prepared from the ventral and dorsal regions of embryonic day 12.5 mouse mesencephalon, and a cDNA fragment was obtained by the subtraction method (N-RDA). The full-length cDNA was cloned and the nucleotide sequence was determined. The gene was named Corl2. The result of homology search showed that about 850 residues of Corl2 exhibited homology to the XM_355050 sequence deposited in GenBank; however, the remaining ˜150 residues showed no homology. Thus, Corl2 was demonstrated to be a novel gene. The Corl2 expression in various mouse organs was analyzed by RT-PCR, and the result showed that Corl2 expression was specific to brain. The result of immunostaining day 12.5 embryos and postnatal day 12 brains demonstrated that Corl2 is useful as a Purkinje cell marker at any differentiation stages.
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.

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.
