Stem Cell Regulation

Human body is exposed to a large variety of chemical, biological and physical hazards, such as toxins, pathogens, pharmaceuticals, radiation and physical injury, just to name a few. These hazards induce damage to our organs and tissues and thereby adversely influence their function that is vital for human survival. Therefore, an episode of tissue injury is generally followed by a rapid and highly organized process of tissue repair and regeneration, and cells that are specialized to perform this duty are called somatic stem cells. These regenerative cells are highly dynamic in nature and respond to several internal and external stimuli, which includes genomic alterations, morphogens, inflammatory cytokines, growth factors, metabolites and microbial products, among others. We are using state-of-the-art genetics and single cell genomic technologies, as well as several in vivo and ex vivo 3D primary tissue culture models to understand how stem cells respond to these molecules in the presence or absence of injury. Findings from these studies are applicable in regeneration medicine.

Medical Genetics

Our primary focus is on intestinal cancer, short-bowel-syndrome, fibrosis, dysplasia and inflammatory bowel disease. Importantly, these human disorders have one thing in common, and that is defective or aberrant regenerative response. We are using human tissues, clinical data and genetic mouse models to understand how regenerative processes are altered during intestinal disease and how this information could be used to restore normal tissue homeostasis in clinical setting.

Personalized Medicine

We are developing high throughput screening methods to test natural and synthetic molecules that could be used for the development of personalized medical treatments against degenerative disorders in human.
