Longitudinal Single Cell Analysis Enabled by Nanopipettes

Physiological and pathological processes within the human body are controlled by complex cell-cell interactions within the context of a dynamic microenvironment. The ability to dynamically measure phenotypes (i.e. gene expression, protein activities, ion fluctuations, signaling) at the single cell level is key to understanding cellular behaviour in a complex environment.<br/>I will present the integration of nanopipettes with scanning probe microscopy techniques to enable the extraction of genetic material from living cells. I will discuss the longitudinal profiling of brain cancer cells to characterize the transcriptional reprogramming at the single cell level after chemotherapy and radiotherapy.
