摘要： Provided is a cell processing method including: preparing a cell suspension containing a cell to be processed and a target substance; and introducing the target substance into the cell to be processed by allowing a shear force to act on the cell to be processed, wherein the cell to be processed is a cell, which is selected from a cell group including cells in a proliferation process, and which has a cell diameter larger than a mode in a cell diameter distribution of the cell group.

摘要： Provided are a liquid injection method, a liquid injection device, and a liquid cartridge capable of suppressing a wasteful consumption of a liquid. To this end, the liquid injection method is to eject a liquid from a liquid injector to a liquid cartridge including a liquid ejection head that ejects the liquid, a channel that is connected to the liquid ejection head and is capable of supplying the liquid to the liquid ejection head, and an opening portion that is connected to the channel and is provided to be wider than the channel. The methods includes directly injecting the liquid into the channel.

摘要： The cell processing method includes a step of passing a liquid containing a cell through an orifice from a flow path by a pressure applying unit, and is characterized in that the orifice is connected to the flow path so as to narrow a flow from the flow path and in that the orifice includes at least any one of a portion in which an area of a cross-section perpendicular to a flow direction of the liquid passing through a center of the orifice is prevented from being changed from an inlet toward an outlet of the orifice or a portion in which the area is increased from the inlet toward the outlet of the orifice. The cell processing apparatus is characterized by including an orifice forming member having the orifice, the flow path, and the pressure applying unit.
