Head of the Laboratory, PhD

The main direction of the laboratory is the study of the functional state of different cell types in the development of pathological conditions such as obesity, diabetes, metabolic syndrome, heart failure.

One of the key objects of study are mesenchymal stromal cells: changing their proliferative and differentiation properties and changing regenerative potential in obesity and diabetes.

One of the research areas of the laboratory is studying the function of ion channel of cardiomyocytes under the influence of adipokines using Patch-Clamp technique. Then, another important methodological approach is the method of laser microdissection, that allows investigating the expression profile of individual cells and tissue structures separately.
