Selection method of iPS cell, preparation method of iPS cell, and control device

A preparation method of an iPS cell, the preparation method comprising:

• at a reprogramming process to culture a cell including a plurality of combinations of initializing factors labelled with luminescent genes that are different with each other, acquiring a luminescence amount of each of the luminescent genes of the cell;
• judging whether the acquired luminescence amount is more than a threshold that is predetermined for the acquired luminescence amount;
• when the acquired luminescence amount is more than the threshold, selecting this cell as an objective cell for a next process;
• and
• transplanting the selected cell to a new culture vessel, repeatedly up to a prescribed number of times.

A control device comprising a processor comprising hardware, the processor being configured to:

• acquire, at a reprogramming process to culture a cell including a plurality of combinations of initializing factors labelled with luminescent genes that are different with each other, a photon number per unit area or a photon number per unit time of each of the luminescent genes of the cell;
• judge whether the acquired photon number is more than a threshold that is predetermined for the acquired photon number;
• and
• when the acquired photon number is more than the threshold, select this cell as an objective cell for a next process.
