Welcome to the Lele Laboratory Homepage

We are located in the Department of Chemical Engineering at the University of Florida.

Cells in our body perform complex tasks, including movement across tissues, adhesion to polymeric scaffolds in the body and the sensing of chemical and mechanical signals. These complex processes depend in large part on the intracellular cytoskeleton. Specialized 'motor' proteins that convert chemical energy into mechanical work associate and move along the polymeric cytoskeleton enabling critical cell functions including intracellular mechanical force generation. We are interested in how the cytoskeleton and associated motor proteins generates forces inside the living cell. This work has applications in understanding diseases of the cardiovascular and muscular system, as well as cancer. We are also developing new biomaterials and nanotechnologies for characterizing and controlling cellular forces.

Research Areas

Cytoskeletal Mechanics
One key challenge in the field of ‘Cell Biophysics’ is that it is difficult to perform measurements inside living cells- a lot of what is known is from experiments with cell extracts or experiments with purified proteins. We have used a new technique- femtosecond laser ablation, to quantify the mechanical properties of the sarcomere- a tensile force generating unit containing actin filaments that associate with myosin motor proteins.

Nuclear Mechanics
Cell motility and polarization require the coordinated motion of intracellular organelles. In particular, positioning of the nucleus is an important part of any dynamic changes in cell morphology, given that it is the largest and stiffest organelle in the cell. We are interested in the mechanism by which nuclear connectivity to the cytoskeleton influences endothelial cell motility, adhesion, mechanotransduction and capillary formation. Read More

 

Nanomaterials
We are interested in controlling cellular contractile forces by fabricating novel types of nanostructures. This research has potential applications in improving cardivoascular and tumor stent performance. Read More
