Published studies using ISET filtration technique to capture CTCs, with a variety of morphological identification techniques.

Studies identifying CTCs from patient blood samples using ISET without the use of epithelial markers. All studies utilised nuclear morphology criteria such as nuclear contour irregularity, nuclear-cytoplasmic size ratio and hyperchromasia but with varying cell/nucleus size criteria and use of the leukocyte common antigen CD45 as a negative marker.
