Abstract
The present invention provides an automated system and method to isolate nucleated blood cells from whole blood or bone marrow. A disc mounted to a centrifuge system with spinning rotor is used to manipulate cells by channeling fluids while subjected to high gravitational field. The disc embodies at least two axisymmetric processing stations connected by a circular channel. Each station contains multiple chambers connected by fluidic channels to controllably transfer fluids. First stage separation allows for the isolation of the buffy coat layer while the second stage separation utilizes gradient density fluids to isolate the targeted nucleated cells from the buffy coat layer in the spinning disc.
