Abstract
Devices and methods for the efficient disaggregation of tissue samples, separating the tissue into individual intact cells or small aggregates of cells for analysis. A device may include a chamber to receive fluid and a tissue specimen containing more than one cell to be disaggregated. The chamber may include an opening and an agitator in fluid contact with the fluid and the tissue specimen. The agitator may include a micromotor which provides rotational motion to a shaft and an impeller fixed to the shaft such that the impeller and the shaft rotate together upon provision of the rotational motion by the micromotor. The device may include an electrical energy source electrically coupled to the micromotor to rotate the impeller sufficient to disaggregate the one or more individual cells from the tissue specimen and in a manner which does not lyse the one or more individual cells.
