We love seeing how our customers continue to push the field forward! This new study from Joram Mooiweer and colleagues at the Dept. of Genetics, University Medical Centre Groningen is a fantastic example of how culture format shapes biology—even when starting from the same iPSC-derived cells. Their head-to-head comparison shows that the Intestine-on-Chip best recapitulates key adult gut functions, including digestion, transport, and metabolism—critical features for drug absorption, DDI, and tox-focused NAMs. Huge congratulations to the team on this important and elegant work!
Now that we're all rushing for human stem cell–based new approach methodologies (#NAMs) for the intestine, on which platform do these cells actually behave most like real intestinal tissue? That's what we wondered too! 👇 We took the same iPSC-derived intestinal epithelium and head-to-head compared: - 3D organoids - 2D Transwell monolayers - An intestine-on-chip system (Emulate, Inc.) under flow 🔬 What we did By tuning key pathways (WNT, BMP, NOTCH, MAPK) and using different media/gradients, we pushed the cells from a proliferative, stem-like state toward more mature epithelial lineages, then profiled them in depth (including RNA-seq) and benchmarked them against in vivo human small intestine datasets. 🧠 What we found - Organoids: capture more fetal / developmental intestinal states - Transwells: show strong ECM remodeling, proliferation, EMT-like features - Intestine-on-chip: shows the highest expression of digestion, nutrient transport and drug metabolism genes and clusters with pediatric/adult small intestine In other words: 👉 For drug absorption, metabolism, DDI and tox-focused #NAMs, the intestine-on-chip looks most “adult gut–like” and functionally relevant 👉 For developmental biology or early tissue states, organoids remain very powerful 👉 For barrier, ECM and EMT-focused questions, Transwells are highly informative 💡So... With the same iPSC-derived cells, your choice of culture system + signaling regime can shift you from fetal-like to adult-like tissue and from proliferative to more functional epithelium. So “organoid vs Transwell vs chip” is not a cosmetic decision – it changes the biology you will read out.
