Growing Intestinal Epithelial Cells May Lead to Personalized IBD Therapies
Intestinal Epithelial CellsTechnology for the growth of human intestinal epithelial cells could help scientists develop individualized therapies for inflammatory bowel disease and other gastrointestinal conditions. This is the conclusion of a group of researchers at Washington University School of Medicine in St. Louis, who recently published a study, entitled, “Development of an enhanced human gastrointestinal epithelial culture system to facilitate patient-based assays,” in the Journal Gut. For this to be possible, the team explained in the abstract of their study that epithelial cells must be enhanced so that biopsies from patients can be used to generate cell lines (which are populations of cells in culture with the same genetic makeup) in a short time frame, so that the analysis can be made accurately. In two weeks, researchers were able to create 65 human gastrointestinal epithelial cell lines from biopsies of 47 patients, taken during routine endoscopic screening procedures. They used a high concentration of conditioned media containing the factors critical for growth, which resulted in a rapid expansion of the proliferative stem and progenitor cells. In addition, the team used a combination of lower conditioned media concentration and Notch inhibition to differentiate these cells for furthe
