# 3D printed scaffold produces gut organoids twice as fast

Researchers at Cincinnati Children's Hospital Medical Center, working with colleagues at Nantes Université, have developed a confined culture system (CCS) that produces [transplantable human gut organoids](https://www.voxelmatters.com/researchers-turn-to-3d-printing-to-improve-probiotics-impact-on-gut-health/) in half the time required by conventional methods — and at ten times the size. 

The method focuses on a 3D printed mold used to fabricate [biocompatible polydimethylsiloxane (PDMS) scaffolding trays](https://www.voxelmatters.com/advanced-solutions-pdms-bioprinting/) with longitudinal confinement lanes. Approximately 4,000 spheroids — the rounded precursor structures that form when stem cell monolayers differentiate — were loaded into the lanes. Once in place, physical confinement prompted them to fuse and elongate into tubular tissue constructs.

By day 14, the resulting structures had reached transplantation maturity, a significant improvement on prior protocols, which required 28 days. After ten weeks of in vivo growth following transplantation into immunocompromised rat models, small intestinal CCS grafts reached widths of 8cm, compared to approximately 1cm under earlier methods. Engraftment rates also improved substantially.

In particular, the CCS approach produced spontaneous co-development of a functional enteric nervous system (ENS) within the organoid tissue. This was achieved without the separate introduction of exogenous neural crest cells, as previously required. Neuromuscular contractile activity was comparable to native human intestinal tissue, and the same results were observed across colonic and gastric organoids.

“By reaching transplantation maturity twice as fast and developing their own functional nerves, these organoids demonstrate how engineering principles can drive biological innovation,” said Holly Poling, PhD, Staff Investigator at Cincinnati Children's and lead on the study.

“Our confined culture system is more than a production method; it's a scalable, flexible platform for building complex human tissues.”

James Wells, PhD, Chief Scientific Director at Cincinnati Children's Center for Stem Cell & Organoid Medicine (CuSTOM) and a study co-author, highlighted the implications for [neurodevelopmental research](https://www.voxelmatters.com/researchers-3d-print-functional-human-brain-tissue/). “This platform's simplicity, reproducibility, and versatility make it accessible for widespread adoption,” he said. “In addition, the emergence of a self-organized nervous system within these organoids is particularly important for further studies of neurodevelopmental disorders.”

The research remains preclinical. Michael Helmrath, MD, Co-Director of CuSTOM and co-author, said further development would be required before CCS-derived tissues enter human trials, but pointed to longer-term therapeutic possibilities.

“We believe such tissues, once transplanted, would further grow and multiply as part of the patient's own organ to restore functions,” Helmrath stated.
