Welcome to the Lele Laboratory
We are located in the Department of Chemical Engineering at the University
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.
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. Read
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
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.
