A research team composed of scientists from New York Institute of Technology and the University of California, Irvine (UC Irvine) has developed an artificial human colon with unprecedented realism. The groundbreaking research project stands to bring safer, more effective cancer treatments to market sooner, while providing a new platform for broader disease research.

As featured in the journal , the cutting-edge project provides the world鈥檚 first functional, drug-testable, 3-D-printed human colon model. In line with to shift away from animal testing in drug development research, the model offers an alternative testing platform that accurately mimics the structural, mechanical, physiological, chemical, and biological complexities of human colon tissue. Co-led bybioengineer , assistant professor at the College of Engineering and Computing Sciences, the project stands to significantly advance understanding of colorectal cancer and pave the way for highly effective precision therapies by providing a lifelike platform for drug efficacy testing. It also lays the groundwork to create highly realistic models of other human organs.

鈥淭his is, to our knowledge, the first model of its kind and represents a true leap forward in biomedical innovation,鈥� says Zanganeh, who ultimately aims to commercialize the prototype. 鈥淲hile this project successfully replicated a human colon, it also opens doors to create functional tissue for virtually any human organ. This breakthrough points to a future in which therapeutic testing can be performed without dependence on traditional cell cultures or animal models, streamlining the path to clinical trials. What once sounded like science fiction is now reality.鈥�

The team used human CT scan data to map the colon鈥檚 anatomy in detail, then employed advanced bioprinting with hydrogels to fabricate a model that mimics its principal layers and functions. Within their engineered model, fabricated at UC Irvine, the team also introduced and successfully treated a tumor, creating a new and powerful platform for cancer drug discovery and disease modeling.

鈥淥ur 3-D, human-relevant colon model overcomes key limitations of 2-D cell cultures and animal studies. It lets us study disease and drug responses in a way that is far closer to the patient, opening a faster, more reliable path to new therapies,鈥� says , assistant professor of electrical engineering and computer science at UC Irvine.

Next, Zanganeh and his research team, which includes doctoral and graduate students from 91社区鈥檚 College of Engineering and Computing Sciences, as well as a student from the College of Osteopathic Medicine, aim to develop additional 3-D tissue models. This includes prototypes capable of withstanding electrical stimulation (recreating conditions that transport substances and molecules across cell membranes) and those replicating immune function. 91社区 student researchers include Engineering, Ph.D. students Armand Ahmetaj and Elahe Zafarvahedian; Bioengineering, M.S. students Ayush Kumar, Gaby Burgos-Crespo, and Yianni Daniil; Bioengineering, B.S. major Anna Dykhno; and medical student Kyle Egan.

鈥淏y combining cutting-edge bioprinting with interdisciplinary collaboration, Dr. Zanganeh and his colleagues have opened a new frontier in cancer research. We are proud to see our faculty leading discoveries with the potential to transform medicine and improve lives worldwide,鈥� says , dean of the College of Engineering and Computing Sciences.
