1. A method comprising:
disassociating a population of cells from a tissue sample, the population of cells including a population of one or more viable cells and a population of one or more dead and dying cells;
exposing the population of cells to at least one pulse of fluid shear stress having a force along a conduit wall of from about 500 dyn/cm2 to about 2500 dyn/cm2 to substantially lyse the population of one or more dead or dying cells, leaving the population of one or more viable cells substantially intact; and
collecting the population of one or more viable cells.
