Pluripotent and Somatic Stem Cell Models to Study Inherited Diarrheal Disorders
Our research group at [REDACTED] has had a long-standing interest in understanding the cause of several disorders that result in severe, and often times fatal forms of diarrhea in children. These diarrheal disorders are inherited, and somehow lead to poor absorption of nearly all forms of nutrients, including protein, sugars and fats. Why children with […]
Mechanism of Tissue Engineered Small Intestine Formation
Short Bowel Syndrome is an expensive, morbid condition with an increasing incidence. Fundamental congenital and perinatal conditions such as gastroschisis, malrotation, atresia, and necrotizing enterocolitis (NEC) may lead to short bowel syndrome (SBS). NEC is the most common gastrointestinal emergency in neonates and primarily occurs in premature infants As rates of prematurity are increasing, so […]
Differentiation of Human Embryonic Stem Cells to Intestinal Fates
The roughly 25 feet of intestine in the adult human play numerous essential roles in daily life, such as nutrient absorption, secretion of hormones, and serving as a barrier to infection. Commensurate with these diverse roles, diseases of the intestine are a considerable source of human morbidity and mortality. Indeed, numerous pathologic conditions including inflammatory […]
Skin-derived precursor cells for the treatment of enteric neuromuscular dysfunction
The intestine performs the essential function of absorbing food and water into the body. Without a functional intestine, children and adults cannot eat normal meals, and these patients depend on intravenous nutrition to sustain life. Many of these patients do not have a neural system that coordinates the function of the intestine. These patients have […]

Stem cell therapy for inflammatory bowel disease
One of the most promising approaches that physicians foresee for treating human disease is regenerative medicine. A major aim in this field is to restore function by repairing damaged organs. Inflammatory bowel disease (IBD) is a chronic disease characterized by intermittent episodes of intestinal inflammation and disruption of the intestinal epithelial barrier. It causes significant […]
The generation and expansion of tissue-engineered small intestine from human stem/ progenitor cells: a preclinical study of functional translation
This proposal aims to complete the preclinical steps to develop tissue-engineered intestine (TESI) as a functional replacement of the small intestine to treat short bowel syndrome (SBS). Common birth conditions especially those associated with prematurity result in SBS wherein 50-75% of the small intestine is gone. SBS children cannot get adequate nutrition and supportive medical […]
hPSC-derived enteric ganglioids for cell therapy in gastrointestinal motility disorders
Research Objective The proposed aims will enable the generation, purification and characterization of enteric neurons from diverse hiPSCs and assessment of their efficacy for cell therapy in GI motility disorders. Impact This proposal addresses a significant unmet clinical need for a cell therapy approach for gastrointestinal motility disorders such as Hirschsprung disease, achalasia and gastroparesis. […]
Drug discovery for gastrointestinal motility disorders using hPSC-derived enteric ganglioids
Research Objective Our goal is to use stem cell models to identify a small molecule drug candidate for GI motility disorders. Impact The candidate will be used for severe gastrointestinal motility disorders including chronic constipation, achalasia and gastroparesis. Major Proposed Activities Assessment of candidate compounds on stem cell derived models from diverse genetic backgrounds Evaluation […]
A new precision medicine based iPSC-derived model to study personalized intestinal fibrosis treatments in pediatric patients with Crohn’s disease
Research Objective We propose to discover a tool that will utilize patient specific iPSC-derived human mini-guts to identify personalized antifibrotic treatments in pediatric Crohn’s disease patients Impact The major bottleneck in intestinal fibrosis research is the difficulty in obtaining patient-specific biologically relevant cells for in vitro modeling. This iPSC-derived tool would overcome it. Major Proposed […]
