Overview
This self-funded PhD project aims to incorporate immunocompatibility assessment early in the design of scaffold structures and determine what architectures elicit a response.
About this opportunity
A plethora of biomaterial scaffolds are researched worldwide for a broad range of tissue applications but consideration of their immune compatibility is often neglected until further down the translational pipeline. By this point considerable time and resources may have been wasted if these scaffolds are subsequently found to have a detrimental effect on cell response and hence are no longer usable for their intended application. This project aims to incorporate immunocompatibility assessment early in the design of scaffold structures and determine what architectures elicit a response.
This PhD project focuses on developing scaffolds of different geometric design using several fabrication technologies (melt electrospinning, melt electrowriting, bioink and extrusion-based printing) and assessing their cellular interactions using a variety of cell types. The project will provide fascinating insight into the design considerations of scaffolds, which are frequently fabricated for a broad range of different applications in tissue regeneration but their impact on immune response is often overlooked until further down the translational pipeline.
Project objectives
Project objectives will include:
- Fabrication of scaffolds using several different technologies to create 2D and 3D structures of variable architecture
- Physicochemical characterisation of these scaffolds (e.g. surface chemistry, mechanical properties)
- Assessment of direct and indirect cell response to these scaffolds using cell lines and primary cells
- Assessment of macrophage, T cell, and mast cell response to these scaffolds
- Assessment of complement activation to these scaffolds.
You’ll undertake a variety of experiments and learn a range of new skills, including fibre production (electrospinning, melt electrowriting, bioink and extrusion-based printing), primary and immortal cell culture, macrophage, T cell and mast cell response, complement activation, imaging (SEM/confocal), in vitro assays, direct/indirect culture, mechanical testing, degradation studies.
