Surface plasmon resonance imaging of excitable cells (2019)
Journal Article
Howe, C. L., Webb, K. F., Abayzeed, S. A., Anderson, D. J., Denning, C., & Russell, N. A. (2019). Surface plasmon resonance imaging of excitable cells. Journal of Physics D: Applied Physics, 52(10), doi:10.1088/1361-6463/aaf849

Surface plasmons (SPs) are surface charge density oscillations occuring at a metal/dieletric interface and are highly sensitive to refractive index variations adjacent to the surface. This sensitivity has been exploited successfully for chemical and... Read More

Simplified footprint-free Cas9/CRISPR editing of cardiac-associated genes in human pluripotent stem cells (2018)
Journal Article
Kondrashov, A., Hoang, M. D., Smith, J. G., Bhagwan, J. R., Duncan, G., Mosqueira, D., …Denning, C. (in press). Simplified footprint-free Cas9/CRISPR editing of cardiac-associated genes in human pluripotent stem cells. Stem Cells and Development, 27(6), doi:10.1089/scd.2017.0268. ISSN 1547-3287

Modelling disease with hPSCs is hindered because the impact on cell phenotype from genetic variability between individuals can be greater than from the pathogenic mutation. While ‘footprint-free’ Cas9/CRISPR editing solves this issue, existing approa... Read More

Drug-mediated shortening of action potentials in LQTS2 hiPSC-cardiomyocytes (2017)
Journal Article
Duncan, G., Firth, K. S., George, V., Hoang, M. D., Stainforth, A., Smith, G., & Denning, C. (2017). Drug-mediated shortening of action potentials in LQTS2 hiPSC-cardiomyocytes. Stem Cells and Development, 26(23), doi:10.1089/scd.2017.0172. ISSN 1547-3287

Cardiomyocytes (CMs) derived from human induced pluripotent stem cells (hiPSCs) are now a well-established modality for modeling genetic disorders of the heart. This is especially so for long QT syndrome (LQTS), which is caused by perturbation of ion... Read More

Can human pluripotent stem cell-derived cardiomyocytes advance understanding of muscular dystrophies? (2016)
Journal Article
Kalra, S., Montanaro, F., & Denning, C. (2016). Can human pluripotent stem cell-derived cardiomyocytes advance understanding of muscular dystrophies?. Journal of Neuromuscular Diseases, 3(3), doi:10.3233/JND-150133. ISSN 2214-3599

Muscular dystrophies (MDs) are clinically and molecularly a highly heterogeneous group of single-gene disorders that primarily affect striated muscles. Cardiac disease is present in several MDs where it is an important contributor to morbidity and mo... Read More

Identification of polymer surface adsorbed proteins implicated in pluripotent human embryonic stem cell expansion (2016)
Journal Article
Hammad, M., Rao, W., Smith, J. G. W., Anderson, D. G., Langer, R., Young, L. E., …Alexander, M. R. (in press). Identification of polymer surface adsorbed proteins implicated in pluripotent human embryonic stem cell expansion. Biomaterials Science, doi:10.1039/c6bm00214e. ISSN 2047-4830

Improved biomaterials are required for application in regenerative medicine, biosensing, and as medical devices. The response of cells to the chemistry of polymers cultured in media is generally regarded as being dominated by proteins adsorbed to the... Read More

Discovery of a novel polymer for human pluripotent stem cell expansion and multilineage differentiation (2015)
Journal Article
Celiz, A. D., Smith, J. G., Patel, A. K., Hook, A. L., Rajamohan, D., George, V. T., …Alexander, M. R. (2015). Discovery of a novel polymer for human pluripotent stem cell expansion and multilineage differentiation. Advanced Materials, 27(27), doi:10.1002/adma.201501351. ISSN 0935-9648

A scalable and cost-effective synthetic polymer substrate that supports robust expansion and subsequent multilineage differentiation of human pluripotent stem cells (hPSCs) with defined commercial media is presented. This substrate can be applied to... Read More

Materials for stem cell factories of the future (2014)
Journal Article
Celiz, A. D., Smith, J. G., Langer, R., Anderson, D. G., Barrett, D. A., Winkler, D. A., …Alexander, M. R. (in press). Materials for stem cell factories of the future. Nature Materials, 13(6), doi:10.1038/nmat3972. ISSN 1476-1122

The materials community is now identifying polymeric substrates that could permit translation of human pluripotent stem cells (hPSCs) from lab-based research to industrial scale biomedicine. Well defined materials are required to allow cell banking a... Read More

Current status of drug screening and disease modelling in human pluripotent stem cells (2013)
Journal Article
Rajamohan, D., Matsa, E., Kalra, S., Crutchley, J., Patel, A., George, V., & Denning, C. (2013). Current status of drug screening and disease modelling in human pluripotent stem cells. BioEssays, 35(3), doi:10.1002/bies.201200053. ISSN 0265-9247

The emphasis in human pluripotent stem cell (hPSC) technologies has shifted from cell therapy to in vitro disease modelling and drug screening. This review examines why this shift has occurred, and how current technological limitations might be overc... Read More

5-hydroxymethyl-cytosine enrichment of non-committed cells is not a universal feature of vertebrate development (2012)
Journal Article
Almeida, R. D., Loose, M., Sottile, V., Matsa, E., Denning, C., Young, L., …Ruzov, A. (2012). 5-hydroxymethyl-cytosine enrichment of non-committed cells is not a universal feature of vertebrate development. Epigenetics, 7(4), doi:10.4161/epi.19375. ISSN 1559-2294

5-hydroxymethyl-cytosine (5-hmc) is a cytosine modification that is relatively abundant in mammalian pre-implantation embryos and embryonic stem cells (Esc) derived from mammalian blastocysts. Recent observations imply that both 5-hmc and Tet1/2/... Read More
