Researchers Study Stem Cell Separation (image) Georgia Institute of Technology Caption Researchers Todd McDevitt and Andres Garcia (l-r), Georgia Institute of Technology, hold microfluidic devices that are used to separate stem cells produced by cell reprogramming techniques. The devices exploit the differences in adhesion strength between derived stem cells and contaminating cell types in a heterogeneous culture to selectively isolate cells of interest using fluid shear forces.
