摘要:
In order to remove a pathogenic effect of a microorganism in a room or a work space in a short period of time, an ion diffusing apparatus, which includes an ion generator (17, 18) for generating positive ions each including H+(H2O)m and negative ions each including O2−(H2O)n, where m and n are arbitrary integers, and a blower for delivering the positive ions and the negative ions, which are generated from the ion generator (17), from a blowout opening, is operated to widely distribute, with a high concentration, the positive ions and the negative ions in the room.

This invention provides a means for modifying surface properties of a cell culture substrate under specific conditions, to thereby regulate regions to which cells are allowed to adhere or are not allowed to adhere, depending on cell type. This invention relates to a method of cell culture comprising steps of: applying a positive potential to a conductive region of a substrate comprising a base material having a conductive region and a non-cell-adhesive membrane coupled thereto with the aid of silane, so as to separate the non-cell-adhesive membrane from the substrate; and culturing cells in a region from which the non-cell-adhesive membrane has been separated.

An object of the present invention is to provide a means for efficiently obtaining mammalian embryos having high conception rates. A first aspect of the present invention is a method for selecting a mammalian embryo prepared by in vitro culture from a fertilized egg, comprising a step of selecting an embryo using two or more of the following indicators: the time from fertilization to the completion of first cleavage; the morphology at a stage after first cleavage and before second cleavage; the morphology at a stage after third cleavage and before fourth cleavage; and the amount of oxygen consumed at the early blastocyst stage, the blastocyst stage, or the expanded blastocyst stage.
