New minimally invasive method allows cells to be sampled over time

At any given moment, a variety of dynamic processes occur inside a cell, with many developing over time. Because current research methods for gene profiling or protein analysis destroy the cell, study is confined to just that one moment in time, and researchers are unable to return to the cell to examine how things change beyond that snapshot.

Scientists develop novel model of liver cancer stem cells from normal iPSCs

Liver cancer is one of the deadliest cancers. It is insidious and does not present symptoms until it has progressed considerably, at which point, treatment options are limited and chances of survival are low. The most common type of liver cancer is hepatocellular carcinoma.
