Adenoviral transduction of mesenchymal stem cells: in vitro responses and in vivo immune responses after cell transplantation
Ritter, Thomas (2012)Adult mesenchymal stem cells (MSCs) are non-hematopoietic cells with multi-lineage potential which makes them attractive targets for regenerative medicine applications. However, to date, therapeutic success of MSC-therapy ... -
Development of a flow cytometry-based potency assay for measuring the in vitro immunomodulatory properties of mesenchymal stromal cells
Ribeiro, Andreia; Ritter, Thomas; Griffin, Matthew; Ceredig, Rhodri (Elsevier, 2016-07-20)Human bone marrow-derived mesenchymal stromal/stem cells (MSC) have well-documented modulatory effects on multiple immune cell types. Although these effects are linked to their therapeutic benefit in diverse diseases, a ... -
Differentiation of vascular stem cells contributes to ectopic calcification of atherosclerotic plaque
Leszczynska, Aleksandra; O'Doherty, Aideen; Farrell, Eric; Pindjakova, Jana; O'Brien, Fergal J.; O'Brien, Timothy; Barry, Frank; Murphy, Mary (Wiley, 2016-02-27)The cellular and molecular basis of vascular calcification (VC) in atherosclerosis is not fully understood. Here, we investigate role of resident/circulating progenitor cells in VC and contribution of inflammatory plaque ... -
Effects of growth phase and temperature on sigma(B) Activity within a Listeria monocytogenes population: evidence for RsbV-independent activation of sigma(B) at refrigeration temperatures
Utratna, Marta; Cosgrave, Eoin; Baustian, Claas; Ceredig, Rhodri H.; O’Byrne, Conor P. (Hindawi Publishing Corporation, 2014-03-05)The alternative sigma factor sigma(B) of Listeria monocytogenes is responsible for regulating the transcription of many of the genes necessary for adaptation to both food-related stresses and to conditions found within the ... -
Evaluation of cartilage repair by mesenchymal stem cells seeded on a PEOT/PBT scaffold in an osteochondral defect
Barron, Valerie; Merghani, Khalid; Shaw, Georgina; Coleman, Cynthia; Hayes, Jessica; Ansboro, Sharon; Manian, Abi; O'Malley, Grace; Connolly, Emma; Nandakumar, Ananda; Van Blitterswijk, Clemen; Habibovic, Pamela; Moroni, Lorenzo; Shannon, Fintan; Barry, Frank; Murphy, Mary (Springer Verlag, 2015-01-15)The main objective of this study was to evaluate the effectiveness of a mesenchymal stem cell (MSC)-seeded polyethylene-oxide-terephthalate/polybutylene-terephthalate (PEOT/PBT) scaffold for cartilage tissue repair in an ... -
Evaluation of the early in vivo response of a functionally graded macroporous scaffold in an osteochondral defect in a rabbit model
Barron, Valerie; Neary, Martin; Mohamed, Khalid Merghani Salid; Ansboro, Sharon; Shaw, Georgina; O'Malley, Grace; Rooney, Niall; Barry, Frank; Murphy, Mary (Springer Verlag, 2015-10-05)Cartilage tissue engineering is a multifactorial problem requiring a wide range of material property requirements from provision of biological cues to facilitation of mechanical support in load-bearing diarthrodial joints. ... -
Immunogenicity of allogeneic mesenchymal stem cells
Ritter, Thomas (2012)Mesenchymal stem cells (MSCs) inhibit proliferation of allogeneic T cells and express low levels of major histocompatibility complex class I (MHCI), MHCII and vascular adhesion molecule-1 (VCAM-1). We investigated whether ... -
Pro-B cells propagated in stromal cell-free cultures reconstitute functional B-cell compartments in immunodeficient mice
von Muenchow, Lilly; Tsapogas, Panagiotis; Albertí-Servera, Llucia; Capoferri, Giuseppina; Doelz, Marianne; Rolink, Hannie; Bosco, Nabil; Ceredig, Rhodri; Rolink, Antonius G. (Wiley, 2016-12-28)Up to now long-term in vitro growth of pro-B cells was thought to require stromal cells. However, here we show that fetal liver (FL) and bone marrow (BM) derived pro-B cells can be propagated long-term in stromal cell-free ... -
Sterile post-traumatic immunosuppression
Islam, Md Nahidul; Bradley, Benjamin A.; Ceredig, Rhodri (Nature Publishing Group, 2016-04-29)After major trauma, the human immune system initiates a series of inflammatory events at the injury site that is later followed by suppression of local inflammation favoring the repair and remodeling of the damaged tissues. ...
