Prof. Suwan Jayasinghe


University College London, UK
Jayasinghe leads the BioPhysics Group at UCL. The group has published over 180 scientific articles, and is internationally recognised through many awards. Jayasinghe’s work has seen the pioneering of supportless 3D electrospray printing, also known as electrohydrodynamic-jet printing. The group has also unearthed discoveries known as bio-electrosprays and cell electrospinning, together with many other non-electric field driven technologies for directly handling living biological cells and embryos. These efforts have contributed to wider areas of research and development, in and within tissue engineering and regenerative biology and medicine. The technologies have recently successfully completed phase II clinical trials. 

Talk title: Cell electrospinning: revolutionising tissue engineering and regenerative medicine

Electrospinning, a century old technology has recently seen its applicability to many areas of research and development. This technology has entered commercial exploitation for the creation of face masks, filters to the clothing industry to name a few. Under the remit of research and development the technology has been investigated for nearly 30 years, as an approach for generating scaffolds for growing and proliferating both specialised and unspecialised cells. Although those studies have contributed to an increased understanding of the utility of such scaffolds in biomedical sciences, its translation to the clinic has been seldom, as the scaffolds have been demonstrated to limit cell infiltration. Cell electrospinning, reimagined the technology where the electrospinning solution would be a biocompatible polymer (hydrogel) accommodating living cells, as a living cell suspension. In 2005 cell electrospinning was discovered and demonstrated to have no negative effects brought on the post-cell electrospun cells from a molecuklar level upwards. Thus, opening the technology for directly handling living cells for forming cell bearing fibres from which living scaffolds are generated for the reconstruction of three-dimensional, fully cellularised scaffolds. Such scaffolds have widespread applicability ranging from the repair, replacement to rejuvenation of damaged and/or aging tissues/organs, biological models, to having implications outside our healthcare, in areas such as our evolving food industry. The talk will introduce the discovery, its capabilities to date and its future.
