Abstract

During development, the gastrointestinal tract undergoes patterning along its anterior-posterior axis to define regions with distinct organs and functions. A new paper in Development derives human intestinal organoids from an individual with duodenal defects and a compound heterozygous variant in the gene encoding the transcription factor RFX6. By studying these organoids, the authors identify novel roles for RFX6 in intestinal patterning. To learn more about the story behind the paper, we caught up with first author J. Guillermo Sanchez and corresponding author Jim Wells, an endowed professor in the Division of Developmental Biology at Cincinnati Children's Hospital, USA, where he is also the Director for Basic Research in the Division of Endocrinology.
