- ItemHeparin-based, injectable microcarriers for controlled delivery of interleukin-13 to the brain(Cambridge : Royal Soc. of Chemistry, 2020) Schirmer, Lucas; Hoornaert, ChloĆ©; Le Blon, Debbie; Eigel, Dimitri; Neto, Catia; Gumbleton, Mark; Welzel, Petra B.; Rosser, Anne E.; Werner, Carsten; Ponsaerts, Peter; Newland, BenInterleukin-13 (IL-13) drives cells of myeloid origin towards a more anti-inflammatory phenotype, but delivery to the brain remains problematic. Herein, we show that heparin-based cryogel microcarriers load high amounts of IL-13, releasing it slowly. Intra-striatal injection of loaded microcarriers caused local up-regulation of ARG1 in myeloid cells for pro-regenerative immunomodulation in the brain. Ā© 2020 The Royal Society of Chemistry.
- ItemOxygen producing microscale spheres affect cell survival in conditions of oxygen-glucose deprivation in a cell specific manner: Implications for cell transplantation(Cambridge : Royal Soc. of Chemistry, 2018) Newland, Heike; Eigel, Dimitri; Rosser, Anne E.; Werner, Carsten; Newland, BenThis study outlines the synthesis of microscale oxygen producing spheres, which, when used in conjunction with catalase, can raise the dissolved oxygen content of cell culture media for 16-20 hours. In conditions of oxygen and glucose deprivation, designed to mimic the graft environment in vivo, the spheres rescue SH-SY5Y cells and meschymal stem cells, showing that oxygen producing biomaterials may hold potential to improve the survival of cells post-transplantation.
