Patent number: 9008406Abstract: Provided are a method capable of discriminating between a colony of differentiated pluripotent stem cells and a colony of undifferentiated pluripotent stem cells, and a method for automatically culturing undifferentiated pluripotent stem cells and a system thereof. A differentiated colony composed of differentiated pluripotent stem cells, an undifferentiated colony composed of undifferentiated pluripotent stem cells and a multilayered colony having pluripotent stem cells stacked in multiple layers are discriminated by processing a photo image of a colony including pluripotent stem cells in a culture vessel. Specifically, a colony having a luminance higher than a first threshold A is determined as a differentiated colony, a colony having a luminance equal to or lower than the first threshold A and equal to or higher than a second threshold B is determined as an undifferentiated colony, and a colony having a luminance lower than the second threshold B is determined as a multilayered colony.Type: GrantFiled: October 7, 2010Date of Patent: April 14, 2015Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Keizo Watakabe, Yohichi Nakamura, Osamu Ohji, Katsumi Nakashima

Patent number: 8977031Abstract: A method and device achieves identification on whether a colony on a cultivation container is differentiated or undifferentiated on an occasion of cultivation of multipotent stem cell, and a method and device achieves a rapid culture of undifferentiated multipotent stem cells. Undifferentiated colony containing only undifferentiated multipotent stem cells is identified from other types of colonies by means of the circularity C of the colony in an image-processed taken image of the inside of cultivation container of a multipotent stem cell. More specifically, when a first threshold of the circularity of the colony is C1, and a second predetermined threshold is C2 (C1<C2), a colony satisfying C2?C is determined as the undifferentiated colony, a colony satisfying C1?C<C2 is determined as an undefined colony, and a colony satisfying C<C1 is determined as the differentiated colony.Type: GrantFiled: June 22, 2011Date of Patent: March 10, 2015Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Keizo Watakabe, Takashi Sakurai, Osamu Ohji, Katsumi Nakashima
