Scientists have made a breakthrough in creating living blood vessels on a chip, mimicking the intricate structures of real human blood vessels. This innovation could revolutionize the study of vascular diseases and drug testing, offering a more accurate and comprehensive approach than traditional laboratory models. The vessel-chip system, developed by researchers at Texas A&M University, is a microfluidic device that can be customized to replicate individual patients' blood vessels, providing a non-animal alternative for studying blood flow and evaluating treatments. The key to this advancement lies in the chip's ability to mimic the complex shapes and structures of real blood vessels, including branched vessels, aneurysms, and stenosis, which significantly impact blood flow patterns and the internal environment of the vessels. This level of detail was previously lacking in simplified laboratory models, which treated blood vessels as straight, uniform tubes.
The research, led by Jennifer Lee, a master's student in biomedical engineering, focuses on creating an advanced vessel-chip that can reproduce the diverse shapes found in actual blood vessels. Lee's work builds upon earlier research in the same lab, where Dr. Tanmay Mathur developed a straight vessel-chip design. The project is part of the Bioinspired Translational Microsystems Laboratory, led by Dr. Abhishek Jain, an associate professor and faculty fellow in biomedical engineering. The team's goal is to advance beyond straight vessel designs and create living vessel chips that can incorporate actual cellular and tissue material, providing a more realistic environment for studying vascular diseases.
Lee's involvement in the project began as an undergraduate honors student seeking hands-on research experience. Despite having little familiarity with organs-on-a-chip technology at the time, her interest in the field's potential for medical research led her to pursue further studies through the Master of Science fast-track program. Lee's perseverance, curiosity, and creativity were instrumental in her rapid uptake of research projects, and she was able to contribute to the development of the vessel-chip technology. The research has been published in Lab on a Chip and will feature on the journal's May 2025 cover.
Looking ahead, the research team aims to expand the complexity of living vessel chips by incorporating additional cell types. This would enable a more comprehensive understanding of how different tissues interact with each other and with flowing blood. Dr. Jain emphasizes the importance of this development, stating that it represents a new direction in the field, focusing on the interaction of cells and flow in more complex architectural states. The project has received support from several major organizations, including the U.S. Army Medical Research Program, NASA, and the National Institutes of Health, among others, highlighting the significance of this research in advancing medical science and technology.
