A very interesting use of fluorescence polarized light microscope by the Marine Biological Laboratory to see internal forces inside cells by observing transmembrane proteins : Integrins.

How do cells move in a certain direction in the body—go to a wound site and repair it, for example, or hunt down infectious bacteria and kill it? Two new studies from the Marine Biological Laboratory (MBL) show how cells respond to internal forces when they orient, gain traction, and migrate in a specific direction. The research, which began as a student project in the MBL Physiology Course and was developed in the MBL Whitman Center, is published in Proceedings of the National Academy of Sciences (PNAS) an

This summer has been very studious for us with the development and validation of new tests in the oncology field. Cytotoxicity assay has been developed in 2D and 3D culture in 96 well-plates as well as wound healing assay on different cell lines. Few examples are presented in this website page “Cytotoxicity in 2D & 3D culture” and scratch assay (wound healing). And to know more on this assay, don’t hesitte to contact us.
