Abstract: The invention provides an antibody that specifically binds to (a) a protein having an amino acid sequence depicted in SEQ ID NO:16 or 32 or (b) a protein which has an amino acid sequence of (a), wherein one to several amino acids are deleted, substituted, or added, and which is specifically expressed in an ES cell.

Abstract: The present invention relates to a probe for selecting ES cells, which characteristically contains one of DNAs having base sequences depicted in SEQ ID Nos; 1, 2, 3, 4, 5, 6, 7 and 8, or DNAs having base sequences depicted in SEQ ID Nos; 9, 11, 13, 15, 17, 19, 21, 23 and 41 and a screening method of ES cell using this probe. Preparation of a probe for selecting ES cells becomes feasible by identifying plural gene with ES cell-specific expressions (ECAT genes) and using the information of the base sequences of these gene groups. Efficient selection of ES cell enables supply of a large amount of ES cell expected to be applicable to regenerative medicine.

Abstract: The present invention relates to a method for constructing human skin tissue, in which human skin tissue is reconstructed on a body surface of an immunodeficient non-human animal.

Abstract: The present invention relates to a method for constructing human skin tissue, in which human skin tissue is reconstructed on a body surface of a non-human animal, which includes: (a) burying a cell-injectable cylindrical chamber into a dorsal skin of an immunodeficient non-human animal, (b) injecting a cell suspension containing a cultured human fibroblast and a cultured human keratinocyte into the chamber, (c) cutting an upper bottom part of the chamber 7 or more days after grafting of the cell to fully open the cylinder part of the chamber, and then (d) eliminating the chamber. The present invention provides a reconstructed human skin which is excellent in terms of quantity and convenience for researching expression of genes and proteins of a human skin or evaluating medicines acting on a human skin, particularly melanocyte.
