A cell colonies dissecting and transplanting apparatus comprises: a base, a platform, a feeding mechanism having at least three axis feeding means, a movable holder, a cutting means, a transplanting means, and a CCD image capturing means. The platform having the CCD image capturing means therebottom is disposed onto the base, and on the platform is defined with the holder for receiving a plurality of loading trays, so as to the original cell colonies and a plurality of media boards of subculture can be placed on the loading trays of holder, the holder can displace from a first axis feeding means and a second axis feeding means of feeding mechanism to moveably align with a first axis and a second axis. In addition, the cutting means and the transplanting means respectively capable of vertically move along a third axis feeding means of feeding mechanism are arranged onto the base, wherein the cutting means is provided with an array of invertable blades, and the transplanting means is defined with a bent capture needle for capturing the cell masses, whereby enabling to use operational analysis of controller to precisely cut, capture and pickedly place the original cell colonies.

An aspiration device for cells or tissues loaded on a container includes a tubular body, a scraper disposed on the tubular body. The scraper scrapes cells or tissues from the container, and the scraped cells or tissues are suctioned into the tubular body. The scraper includes a connecting portion connected to the tubular body, an elastic portion connected to the connecting portion, and a scraping end connected to the elastic portion. When the scraper scrapes the cells or the tissues, the elastic portion deforms elastically to enable the scraping end to abut the surface of the container, thus, the cells or tissues are scraped.

A dissection device for organisms includes a table bearing an organism and at least one blade lifted or lowered to approach the table. The blade includes a connecting portion, a cutting portion having a curved edge, and a neck portion connecting the connecting portion and the cutting portion. When the blade is lowered to contact the table, the cutting portion is rotated with respect to the neck portion to have rolling contact with the table from a first point to a second point of the edge.

A selecting apparatus for selecting cell/tissue mass includes a base, a feeding mechanism and a dividing mechanism. The base has a platform for placing the cell/tissue mass. The feeding mechanism, disposed on the base, moves relative to the platform. The dividing mechanism, disposed on the feeding mechanism, includes a first cutting set and a second cutting set connected therewith. The second cutting set reciprocally moves between a first position and a second position, toward the first cutting set. The feeding mechanism moves the dividing mechanism above the platform, aligning the dividing mechanism with a portion of the cell/tissue mass, and moves the first cutting set toward the cell/tissue mass, cutting into the portion of the cell/tissue mass. The second cutting set moves from the first position to the second position, limiting the portion of the cell/tissue mass between the first cutting set and the second cutting set.

摘要:
Provided herein are human embryonic stem cells and their method of culturing. In one embodiment, the human embryonic stem cells are maintained in an environment containing an extracellular matrix isolated from feeder cells and a conditioned medium pre-conditioned by the feeder cells; the feeder cells are pre-inactivated by either gamma ray radiation or by mitomycin C treatment. The cultured human embryonic stem cells remain substantially undifferentiated and maintain their pluripotency to differentiate into three germ layer cells.
摘要:
The present invention discloses an improved culture system for proliferative and undifferentiated growth of human embryonic stem cells, comprising an extracellular matrix prepared from feeder cells and a conditioned medium preconditioned by feeder cells. This invention also relates to a culture method utilizing the foregoing culture system.
