Abstract

Methods for isolating viable cancer cells from a sample that comprises a mixture of cancerous cells and normal (non-cancerous) cells are provided. In the methods, a fluid preparation comprising a mixture of cancerous and normal cells is repeatedly exposed to fluid shear stresses, whereby the repeated exposure to the fluid shear stresses preferentially imparts fluid shear stress-resistance to the cancerous cells.
