Meet Dr. Astero Klampatsa, who uses the Compresstome vibrating microtome for thoracic cancer research at the University of Pennsylvania!
The Compresstome® Vibrating Microtome in the Albelda Lab:
Dr. Astero Klampatsa works at the Penn Center for Lung Biology, Division of Pulmonary, Allergy and Critical Care Medicine at Penn. Her lab is headed by principle investigator Dr. Steve Albelda, who is interested in understanding the immune microenvironment of mesothelioma and lung cancer, and on developing CAR T-cell therapies for these types of malignancies.
Using lung slices from patient tumors, Dr. Klampatsa studies their endogenous immune components. Precision-cut lung slices (PCLS) made with the Compresstome vibrating microtome allow her to treat samples with novel therapies, like CAR T cells or antibodies, ex vivo and measure response .
Here, we would like to showcase some of Dr. Klampatsa’s amazing work using precision-cut lung slices. Note that tissue slices made with the Compresstome vibrating microtome can be used for physiological studies, as well as for H&E and fluorescent protein staining.
