Nanotubes mimic capillaries to study mitosis, metastasis
W. Xi et al/ACS Nano 2016
Scientists have found a new way to study how cancer cells divide and thrive in difficult-to-reach crannies of the body.
Transparent artificial membranes — just nanometers thick — can be rolled into tubes to mimic capillaries that host spreading cancer cells, researchers report in the June ACS Nano. Cells squished inside such tubes didn’t organize their internal components the way they normally do before splitting. As a result, the cells divided unevenly, potentially introducing new mutations.
