Characterization of an in vitro model of intestinal cells as a test-bed for mCIPO therapies
Abstract:
Chronic Intestinal Pseudo-Obstruction in children (CIPO) comprises a group of ultra-rare and debilitating diseases characterized by severe motility defects affecting the entire digestive tract. With limited effective therapies, particularly for myopathic CIPO, we aim at characterizing the behavior of an intestinal smooth muscle cell line undergoing a set of chemical and physical stimulations, to assess their effect. To this end, we adopted healthy Human Intestinal Smooth Muscle Cells, plated on standard coverslips and, for the first time, Micro Electrode Arrays (MEAs). After obtaining stable cultures, we performed pharmacological and electrical stimulation, evaluating the contraction level as readout. We found an increase in the contraction levels ascribable to stimulation respect to basal condition. Our results can be considered introductory for new therapies for treating intestine motility disorders.
Insights
Researchers studied human intestinal smooth muscle cells to understand motility disorders in children. Chemical and electrical stimulations increased cell contraction, offering insights for new therapies for Chronic Intestinal Pseudo-Obstruction.
Area of Science:
