Improved blood vessels make better ‘mini-brains’ in the lab

Scientists have discovered a new approach to growing mini-brains in the lab which gives them long enough lifespan to explore function and disease in cells.    The research team led by Dr Mihai Lomora, a scientist with CÚRAM - the Research Ireland Centre for Medical Devices based at University of Galway, grew the small blobs of brain cells in a soft, biologically compatible material called a hydrogel and introduced cells that can form blood vessels.    The result was that the cerebral organoids grew larger with fewer cells dying in the centre, and they mimicked features of the protective blood-brain barrier, potentially making them more relevant lab models to study diseases such as stroke, Alzheimer’s, and Parkinson’s Disease.   The findings have been published in the prestigious journal Advanced Science.   Dr Lomora, a lecturer in Biomaterial Chemistry, lead of the CerebroMachines Lab and member of the Institute for Health Discovery & Innovation, University of Galway, said: “Growing ‘mini-brains’ in the lab might sound like science fiction. But it’s not so far-fetched. Scientists around the world today grow small ‘cerebral organoids’ made of brain cells.   “When we started the project, we could see in the scientific literature that cerebral organoids growing in the lab tended to have a vasculature or blood vessels that were superficial only. That meant that the blood vessels didn’t penetrate in to reach the deeper cells in the organoid, then these cells became starved of oxygen and nutrients over time and they died off.”   The research project involved a multi-disciplinary team based in CÚRAM, University of Galway, RCSI University of Medicine and Health Sciences, Trinity College Dublin and the University of Edinburgh.   The team took an approach to help overcome the issue of viability of an organoid – tiny clumps of tissue, only a few millimetres across and just about visible to the naked eye. One of the main problems with these collections of brain cells is that as they get bigger, a lack of blood supply means the inner core dies off.   In order to get enough oxygen and nutrients to all of the cells, researchers adapted an existing protocol, or recipe, for growing the cerebral organoids, experimenting with different environments and timings to optimise the ability of blood vessels to reach these deeper cells.    The more blood-vessel-friendly approach resulted in three times less cell death in the organoids, and the researchers saw evidence that the organoids contained characteristics of an important protective feature naturally found in the brain called the blood-brain barrier.   Dr Lomora added: “We were fascinated to see that the vasculature really was able to protrude towards the interior of the organoids, which actually was quite a big advancement. And we also saw that cells involved in forming some of those blood vessels came from the organoid itself.  It's at the edge of the state of the art for now.  “Obviously this is not the same as growing a brain in the lab, but it is a mini-model of how parts of the brain work, and we want it to be as physiologically relevant as possible. We believe that by increasing the vasculature we have taken steps to making the organoids more physiologically relevant.”   The organoids are now being used by researchers in the CÚRAM network to explore brain function and disease, including stroke.   The research paper is available at Advanced Science.   Ends

New research into the arrangement of sugar chains or ‘glycans’ in the cells of the spine has shed light for the first time on the critical role it plays in the complex process of disc degeneration.   Researchers at CÚRAM - Research Ireland Centre for Medical Devices at University of Galway, together with a team of international colleagues, carried out a comprehensive investigation into the different characteristics of glycans in healthy and degenerated intervertebral discs.   It is the first time that the whole human disc glycome in the spine - the entire set of sugar chains that modify human proteins and lipids - have been analysed in this way.    Intervertebral disc (IVD) degeneration is a major cause of low back pain, a significant global health issue. While glycosylation is critical for cellular signalling and inflammation, its malfunction can lead to diseases and its role in IVD degeneration has remained poorly understood until the research was conducted.   Dr Kieran Joyce, first author of the paper, said: “From this research, we now know which sugars are expressed in the degenerated or diseased disc states, so we can design therapies to target this.   “We observed distinct alterations in glycan expression, notably an overabundance of sialic acid on the surface of the cells in degenerated discs and decreased branching, which are associated with IVD degeneration. These observed differences have implications for regulating inflammatory responses and other cellular activities.”   Professor Abhay Pandit, Scientific Director of CÚRAM and senior author of the research paper, said: “Our findings suggest that there is therapeutic potential in using biomaterial systems to intervene and alter the way proteins and glycans attach to each other to reduce inflammation associated with IVD degeneration. This research significantly advances our knowledge of the glycomic mechanisms underlying IVD degeneration and opens new avenues for developing therapies to restore disc physiology.”   The finding of the research have been published in Advanced Science and can be accessed at https://advanced.onlinelibrary.wiley.com/doi/10.1002/advs.202506669?af=R.   The project was carried out by CÚRAM researchers at University of Galway in collaboration with colleagues at Maynooth University, University College Dublin, the National Institute for Bioprocessing Research and Training (NIBRT), the Medical University of South Carolina and the Institute of Chemical Technologies and Analytics in Austria.   Ends

University of Galway’s Institute for Clinical Trials has been awarded the 2025 Collaboration in Medtech Award at the Irish Medtech Awards.  The accolade recognises the Institute’s outstanding leadership in advancing early-stage medtech innovation through high-impact clinical partnerships, including the establishment of the Hypercare initiative to supports partners in the clinical trials approval process.   It is the second year in a row in which University of Galway has won the Collaboration in Medtech Award.   Established in 2023, the Institute for Clinical Trials is focused on transformation of the clinical research landscape in Ireland by creating an environment where scientific advances are translated into improved care for patients.  The 2025 Collaboration in Medtech Award was secured for the Institute’s Hypercare initiative, which has been developed to transform how early-stage medtech trials are delivered in Ireland. The initiative is a national pilot, designed to support  industry collaborators in navigating complex approval processes for a clinical trial, from ethics and regulatory submission to system requirements of the Health Service Executive, through to initial patient enrolment.   Aligned with the mission of the Institute for Clinical Trials, this project drives excellence, inclusivity, and need-driven research to improve global health outcomes. Clinical trials increase the opportunities of patients to have early access to innovative treatments that could improve, extend or even save their lives.  Encouraging more research must be a priority for those bodies charged with improving the nation’s health and the Hypercare initiative seeks to support this by ensuring Ireland is a location of choice for early feasibility/phase MedTech trial conduct and delivery. The Hypercare project aims to highlight positive changes in the delivery of clinical research in Ireland, attracting further interest and investment from MedTech stakeholders nationally and internationally.             Professor Fidelma Dunne, Director of the Institute for Clinical Trials at University of Galway, said: "It is a real honour for the Institute to win the 2025 Collaboration in Medtech Award. Collaboration is at the heart of everything we do at the Institute for Clinical Trials, and this recognition reflects the commitment of our team and our partners.   “The Hypercare initiative stands out as the model for academic–industry collaboration, advancing innovation while upholding the highest clinical and regulatory standards. By working closely with innovators, from early-stage start-ups to global leaders, we are making great strides in demonstrating where Ireland can lead in the world of clinical trials as well as accelerating the delivery of new technologies that can truly improve patient outcomes at home and across the globe."            Hypercare has successfully supported four companies to date through the pilot, two of which have launched a first-in-human use of their device in Ireland – Medtronic and Intervene.   By bringing together clinical expertise, regulatory guidance, and real-world testing, the Institute helps partners move through approvals in a more structured and predictable process and therefore more quickly through early clinical validation with the hope of bringing new helathcare solutions to patients in Ireland and beyond.  The Collaboration in Medtech Award celebrates the Institute’s success in forging partnerships that strengthen Ireland’s position in medtech and support a more collaborative, efficient, and innovative approach to clinical research.  Irish Medtech, the Ibec group that represents the medtech sector, Enterprise Ireland and IDA Ireland held the awards as part of Medtech Rising, an annual conference for the sector held this year at The Galmont Hotel in Galway.  Ends
