Cellular impedance measurement- novel method for in-vitro investigation of drug efficacy

Sep 12, 2017

Using standard cell lines, although attractive, can lead to unexpected results and probably to important differences when investigating a drug in primary cell lines isolated from patients. The opportunity to use cells of human origin may improve the predictive value of assays in drug testing and came hand in hand with the development of innovative real-time monitoring of cellular behaviour.

xCELLigence real time cell analyser offers a label-free non-invasive manner long-term recording of cellular signals. Considering all this aspects, the aim of our research was to evaluate the impedance of the primary melanocytes isolated from excised tumours that were confirmed as cutaneous melanoma. Primary cell cultures were used for establishing the efficacy pattern of a standard cytostatic, dacarbazine.
Our goal stands for obtaining a work flow for validating specific drug’s efficacy in individual tumour cells as a mean to personalize therapy in melanoma.
