摘要:
Provided is a method of improving the efficiency of iPS cell establishment, comprising bringing one or more factors selected from the group consisting of proteins belonging to cyclin D family and nucleic acids that encode the same into contact with a somatic cell, in the step of nuclear reprogramming of the somatic cell. Also provided are a method of producing an iPS cell comprising the step of bringing the factor(s) and nuclear reprogramming substance(s) into contact with a somatic cell, an iPS cell comprising a nucleic acid that encodes a protein belonging to cyclin D family that can be obtained by the method of producing an iPS cell, and a method of somatic cell production by forcing the iPS cell to differentiate.

Induced pluripotent stem cells are produced from human somatic cells by co-culturing human somatic cells having a reprogrammed nucleus with human cells as feeder cells. Induced pluripotent stem cells are produced from somatic cells by co-culturing somatic cells having a reprogrammed nucleus with autologous cells as feeder cells. Induced pluripotent stem cells are cultured with culture supernatant of somatic cells.

For efficient proliferation of pluripotent stem cells in a system free from any animal-derived material such as feeder cells or serum, the present invention provides a method for proliferation of pluripotent stem cells, which comprises culturing the pluripotent stem cells in a medium free from both feeder cells and serum in a system containing laminin-5.
摘要:
In a laser exposure device according to the present invention, a positioning pin, which is formed in a lens holder supporting a lens system, is inserted through an elongated hole for restriction of a board holder supporting a laser diode. An eccentric cam is inserted into an elongated hole for rotation movement formed in a board holder and a circular hole for rotation movement which is formed in the lens holder and which faces the elongated hole for rotation movement. An eccentric cam is inserted into an elongated hole for slide movement formed in the board holder and a circular hole for slide movement which is formed in the lens holder and which faces the elongated hole for slide movement. The eccentric cams are rotated to relatively move the board holder and lens holder with respect to each other to thereby establish alignment between the optical axes of the laser diode and lens system. In a state where the eccentric cams are fitted into the elongated holes, the board holder and lens holder are fixed to each other by screws.
