Title: Device and method for the separation of human or animal cells of different densities from cellular dispersions which contain them

Abstract: A device and a method are provided to efficaciously and rapidly separate human or animal cells of different densities from the dispersions which contain them, the device comprising an elongated chamber containing at least a first channel, one end of which opens on the inside of the chamber near the base and a second channel whose end opens in the chamber at a level corresponding to the top of the device, and wherein there is at least a third additional channel, one end of which opens at an intermediate level of the chamber; and the method comprises introducing a dispersion of such cells into the chamber previously filled with a liquid with increasing density gradient, followed by centrifugation and by recovering the distinct fractions of cells with different densities through at least one hole situated at an intermediate level of the chamber length.
