Cellular interactions in the tumour microenvironment during inflammation-associated carcinogenesis
O'Malley, Grace (2017-11-30)The colon tumour microenvironment is highly stromal in composition and a greater stromal cell density correlates with a poor prognosis for patients. The majority of these stromal cells are of mesenchymal origin (MSCs) and ... -
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. ... -
Stromal cell PD-L1iInhibits CD8(+) T-cell antitumor immune responses and promotes colon cancer
O'Malley, Grace; Treacy, Oliver; Lynch, Kevin; Naicker, Serika D.; Leonard, Niamh A.; Lohan, Paul; Dunne, Philip D.; Ritter, Thomas; Egan, Laurence J.; Ryan, Aideen E. (American Association for Cancer Research, 2018-11)Stromal cells of mesenchymal origin reside below the epithelial compartment and provide structural support in the intestine. These intestinal stromal cells interact with both the epithelial cell compartments, as well as ... -
TGF-ß1-Licensed Murine MSCs show superior therapeutic efficacy in modulating corneal allograft immune rejection In Vivo
Lynch, Kevin; Treacy, Oliver; Chen, Xizhe; Murphy, Nick; Lohan, Paul; Islam, Md Nahidul; Donohoe, Ellen; Griffin, Matthew D.; Watson, Luke; McLoughlin, Steven; O'Malley, Grace; Ryan, Aideen E.; Ritter, Thomas (Elsevier, 2020-05-29)Mesenchymal stromal cells (MSCs) are a promising therapeutic option for multiple immune diseases/disorders; however, efficacy of MSC treatments can vary significantly. We present a novel licensing strategy to improve the ...
