Journal Article
Abu-Awwad, H. A.-D. M., Thiagarajan, L., & Dixon, J. E. (2017). Controlled release of G AG-binding e nhanced t ransduction (GET) peptides for sustained and highly efficient intracellular delivery. Acta Biomaterialia, 57, 225-237. https://doi.org/10.1016/j.actbio.2017.04.028

Controlled release systems for therapeutic molecules are vital to allow the sustained local delivery of their activities which direct cell behaviour and enable novel regenerative strategies. Direct programming of cells using exogenously delivered tra...

Highly efficient intracellular transduction in three-dimensional gradients for programming cell fate (2016)
Journal Article
Eltaher, H. M., Yang, J., Shakesheff, K. M., & Dixon, J. E. (2016). Highly efficient intracellular transduction in three-dimensional gradients for programming cell fate. Acta Biomaterialia, 41, 181-192. https://doi.org/10.1016/j.actbio.2016.06.004

Fundamental behaviour such as cell fate, growth and death are mediated through the control of key genetic transcriptional regulators. These regulators are activated or repressed by the integration of multiple signalling molecules in spatio-temporal g...

Highly efficient delivery of functional cargoes by the synergistic effect of GAG binding motifs and cell-penetrating peptides (2016)
Journal Article
Dixon, J. E., Osman, G., Morris, G. E., Markides, H., Rotherham, M., Bayoussef, Z., El-Haj, A., Denning, C., & Shakesheff, K. M. (2016). Highly efficient delivery of functional cargoes by the synergistic effect of GAG binding motifs and cell-penetrating peptides. Proceedings of the National Academy of Sciences, 113(3), E291-E299. https://doi.org/10.1073/pnas.1518634113

Protein transduction domains (PTDs) are powerful nongenetic tools that allow intracellular delivery of conjugated cargoes to modify cell behavior. Their use in biomedicine has been hampered by inefficient delivery to nuclear and cytoplasmic targets....

Cell Reports, 7(5), 1353-1361. https://doi.org/10.1016/j.celrep.2014.05.003

5-Methylcytosine (5mC) is an epigenetic modification involved in regulation of gene activity during differentiation. Tet dioxygenases oxidize 5mC to 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC), and 5-carboxylcytosine (5caC). Both 5fC and 5...

Proceedings of the National Academy of Sciences, 111(15), 5580-5585. https://doi.org/10.1073/pnas.1319685111

The ability of materials to define the architecture and microenvironment experienced by cells provides new opportunities to direct the fate of human pluripotent stem cells (HPSCs) [Robinton DA, Daley GQ (2012) Nature 481(7381):295-305]. However, the... Read More about Combined hydrogels that switch human pluripotent stem cells from self-renewal to differentiation.
