“Recent studies suggest a possible association between dephosphorylated-uncarboxylated MGP (dp-ucMGP) and glomerular filtration rate (GFR). This study aimed to establish normative data in an adult Caucasian population and to explore the potential utility of dp-ucMGP in patients with diabetes mellitus (DM) with and without diabetic kidney disease (DKD).”
“Human mesenchymal stromal cells broadly modulate high glucose-induced inflammatory responses of renal proximal tubular cell monolayers” authored by Md Nahidul Islam, Tomás P. Griffin, Elizabeth Sander, Stephanie Rocks, Junaid Qazi, Joana Cabral, Jasmin McCaul, Tara McMorrow and Matthew D. Griffin at NUI Galway was published today, the 19th of November 2019. The open-access paper appears in Stem Cell Research & Therapy (2019) 10:329, DOI: 10.1186/s13287-019-1424-5 You can download the pdf here.
Renal proximal tubular epithelial cells (RPTEC) are dysfunctional in diabetic kidney disease (DKD). Mesenchymal stromal cells (MSC) may modulate DKD pathogenesis through anti-inflammatory mediators. This study aimed to investigate the pro-inflammatory effect of extended exposure to high glucose (HG) concentration on stable RPTEC monolayers and the influence of MSC on this response.
Morphologically stable human RPTEC/TERT1 cell monolayers were exposed to 5 mM and 30 mM (HG) D-glucose or to 5 mM D-glucose + 25 mM D-mannitol (MAN) for 5 days with sequential immunoassays of supernatants and end-point transcriptomic analysis by RNA sequencing. Under the same conditions, MSC-conditioned media (MSC-CM) or MSC-containing transwells were added for days 4–5. Effects of CM from HG- and MAN-exposed RPTEC/MSC co-cultures on cytokine secretion by monocyte-derived macrophages were determined.
After 72–80 h, HG resulted in increased RPTEC/TERT1 release of interleukin (IL)-6, IL-8, monocyte chemoattractant protein (MCP)-1 and neutrophil gelatinase-associated lipocalin (NGAL). The HG pro-inflammatory effect was attenuated by concentrated (10×) MSC-CM and, to a greater extent, by MSC transwell co-culture. Bioinformatics analysis of RNA sequencing data confirmed a predominant effect of HG on inflammation-related mediators and biological processes/KEGG pathways in RPTEC/TERT1 stable monolayers as well as the non-contact-dependent anti-inflammatory effect of MSC. Finally, CM from HG-exposed RPTEC/MSC transwell co-cultures was associated with attenuated secretion of inflammatory mediators by macrophages compared to CM from HG-stimulated RPTEC alone.
Stable RPTEC monolayers demonstrate delayed pro-inflammatory response to HG that is attenuated by close proximity to human MSC. In DKD, this MSC effect has the potential to modulate hyperglycemia-associated RPTEC/macrophage cross-talk.
Prof. Matt Griffin of the National University of Ireland Galway visited the Division of Nephrology and Hypertension and the William J von Liebig Transplant Center at Mayo Clinic, Rochester, Minnesota between September 27th and October 2nd, 2019. While there, he engaged with clinical investigators involved in a range of Mayo Clinic research initiatives in regenerative medicine and transplantation. He gave seminars entitled “Modulating the course of diabetic kidney disease: Are the pieces coming together?” and “Allogeneic MSC in Corneal Re-transplantation: From Pre-clinical Evidence to Regulatory Approval” which focussed on the progress of the NUI Galway-coordinated NEPHSTROM and VISICORT (www.visicort.eu) consortia respectively.
Commenting on the visit, Prof. Griffin, who trained and was a faculty member at Mayo Clinic between 1992 and 2008 said: “There are many shared interests and collaborative links between leading academic centres in the US such as Mayo Clinic and European Commission-funded consortia such as NEPHSTROM and VISICORT. Looking ahead to the next EU research and innovation programme, Horizon Europe, I believe that there will be exciting opportunities to further strengthen these links in the areas of regenerative medicine and cellular therapies for the long-term benefit of people with reduced quality of life due to chronic health conditions.”
NEPHSTROM Coordinator Professor Timothy O’Brien, Dean of the College of Medicine, Nursing and Health Sciences at NUI Galway and Consultant Endocrinologist at Galway University Hospitals has received the Mayo Clinic Distinguished Alumni Award. The award was established by the Mayo Clinic Board of Trustees in 1981 to acknowledge and show appreciation for exceptional contributions of Mayo Clinic alumni to the field of medicine.
Professor O’ Brien is an internationally recognised clinician-scientist with expertise in regenerative medicine applied to the treatment of diabetes complications. He has influenced a generation of Irish clinicians and scientists. His ties to Mayo Clinic allow trainees from NUI Galway and Galway University Hospitals to spend time at Mayo Clinic and for Mayo faculty to spend time in the University and hospital in Galway, ensuring that the Mayo Clinic ethos is evident on the wards, and in the clinics and laboratories, in Ireland. He is also a director of the Regenerative Medicine Institute at NUI Galway and is lead endocrinologist at Saolta University Health Care Group and co-director of CÚRAM, the SFI Centre for Research in Medical Devices at NUI Galway.
In addition to his administrative and leadership responsibilities, Professor O’ Brien has a major teaching commitment to the School of Medicine at NUI Galway and was twice awarded the Pat McHugh Medal for Best Consultant Teacher. He maintains a busy clinical practice in general internal medicine, diabetes, endocrinology and metabolism. He established a Bariatric Medicine Clinic in Galway University Hospitals, one of only two such centres in Ireland.
Previously Professor O’ Brien was an endocrinologist at Mayo Clinic in Rochester and an associate professor of medicine at Mayo Clinic College of Medicine and Science.

The NEPHSTROM project team recently had another very successful and productive plenary meeting in Bergamo, Italy hosted by NEPHSTROM partner Azienda Ospedaliera Papa Giovanni XXIII Bergamo. The meeting began with a warm welcome by NEPHSTROM Coordinator Prof Tim O’Brien, NUI Galway and proceeded to a lively and productive discussion of NEPHSTROM’s work, with a particular focus on the ongoing clinical trial and the potential for the commercial exploitation of NEPHSTROM’s work.
The HRB Clinical Research Facility Galway in Ireland hosted a public event to celebrate International Clinical Trials Day on May 20th 2019. Exhibition stands were on display and informational meetings were held throughout the day to inform the public of all areas of clinical research being undertaken at the facility.
A particular stand was dedicated to the CRF Galway’s stem cell work to inform the public of the cell therapy projects being undertaken with partners within the National University of Ireland Galway and with European partners. NEPHSTROM was showcased here, as were the related projects VISICORT and ADIPOA-2.
Dr Veronica McInerney comments, “Great interest was expressed in this evolving therapeutic area with approximately 100 members of the public stopping by to hear about what cell therapy involves and to learn about the projects from the clinical researchers on the day.”
Congratulations to NEPHSTROM researchers at NUI Galway who have recently published three papers:
