Cellular Biophysics

Marie-Pierre Rols

Group Leader

The main goal of our interdisciplinary group is to study the mechanisms of molecule delivery into cells and tissues by electric fields and to develop new tools for delivery, targeting and diagnostic. For that, we adapt and improve different complementary systems with increasing complexities (liposomes, cells in culture, spheroids and mice) and integrate various imaging tools to visualize and define membrane and cell permeabilization at the molecular level.



We develop a multidisciplinary approach combining cell biology and biophysics to determine the mechanisms of membrane perturbations induced by transmembrane potential modifications, i.e. by the electroporation or electropermeabilization technique.These studies bring new approaches and guidelines for safe and efficient delivery of therapeutic molecules into cells and tissues since delivery requires targeting molecules towards specific cells.

In that context, and based on our previous works, the main objectives we pursued are:

•Elucidation of the mechanisms of electrotransfer: our works give evidence of the differences between the transfer of small molecules (bleomycin, cis-platinium), small oligonucleotides (siRNA, LNA), proteins and plasmid DNA and between the mechanisms involved in vitro on cells in culture (2-dimensional and 3-dimensional models) and in vivo on tissus (murine model).

•Development of new tools for delivery, targeting and diagnostic: our results have led us to define new types of electrical pulse generators and electrodes (adapted for study in vitro and in vivo models) and to adapt imaging systems (dorsal window chamber, fluorescence micro and macroscopies). In addition, we are developing other non-viral drug delivery approach based on lectin and we are using DNA aptamers that bind specifically to cancer cells. This approach has interests for Targeting of tumours (drug delivery) and Diagnostics (imaging of solid tumors).


We work in collaboration with laboratories worldwide in the context of several international networks (International Bioelectrics Consortium, COST Action TD1104: European network for development of electroporation-based technologies and treatments and LIA-EBAM: International Associated Laboratory on Pulsed Electric Fields Applications in Biology and Medicine).

3rd Price of the 25th "concours innovation Midi-Pyrénées" , Section « laboratory and research teams » :

  • J.TEISSIE, MP. ROLS, M. GOLZIO, Y. TAMZALI, B.COUDERC. Device for eradication of horses cutaneous tumors by electrochemo- and electrogenotherapy.

Application for Technology Transfer : « Fluorescence imaging device for small animals (whole body)» Date of the comity : 20 Avril 2006. N° AV ou N° St DI 00745-01

  • The invention is a device which allows the study, by fluorescence imaging, of few centimeters objects. The inventive activity does not allow to apply for a patent : this is a combination of well-known elements that could be evident for an expert. However, this could be a skill, specially in micro biology.
  • The "Comité des Engagements" gave a favorable verdict to Technology transfer via "Licence de Savoir-Faire".
