3D nano-structure models

for reproductive immuno-biology

 

Project information

This is a Doctoral Programme Studentship in a collaborative project between The Royal Veterinary College, London; The Nano-Medicine Group, Swansea; and Pfizer, Sandwich.

 

Background

Uterine disease and sexually transmitted infections are widespread and cause considerable infertility in humans and the domestic animals that provide food for man. Further, chronic inflammation associated with these infections may be an important cause of uterine and ovarian cancer, which has a high mortality. Investigating the mechanisms underlying the immuno-biology of ovarian and uterine infertility depend on the 2D mono-culture of cells from the ovary and uterus. But we live in a world of 3D multi-cellular structures, which are the spherical ovarian follicle that contain the mammalian egg, and the epithelial and stromal cells that form the endometrium and glands, which nurture the fetus. We have an integrated cross-discipline approach to develop 3D models that can be exploited to study infection, immunity, cancer and toxicology in the genital tract of humans and animals.

 

Project

The project will use engineered nano-structures to host ovarian or uterine cells that facilitate the “self-assembly” of ovarian follicles and uterine endometrium. The impact of the shape and form of the nano-structures will be evaluated by measuring mechanical forces at the cellular level and testing biological function.  The optimal 3D models will be used to test the effect of infection on endocrine and immune function.

 

The project is at the interface between medicine, biology and engineering. The student will be exposed to three rich research environments: London, Swansea and Pfizer working in well-funded groups. This mix of environments provides access to some of the most advanced technology including atomic force and confocal microscopy and nano-engineering facilities as well as biological laboratories experienced in the cell and molecular techniques required. We are also collaborating with Prof David Albertini, Kansas, and Prof Robert Brown, UCL, who have considerable experience in the field.

 

We are seeking an enthusiastic and motivated individual with a first or upper second class science degree. The studentship will provide fees at UK/EU level and a PhD stipend tenable from October 2007.

 

Training

The project is split into three equal parts. Firstly, at the RVC, the student will train in cell biology with a BBSRC Research Development Fellow (Sheldon), a Post Doctoral Assistant, an Underwood Fellow (Prof Gadsby; North Carolina), and another BBSRC CASE student. Then the student will join the Nano-Medicine Group at the new Institute of Life Science in Swansea, developing models with human as well as animal cells.  The final stage is working in the world-leading Discovery Biology laboratories at Pfizer, Sandwich, using the 3D models. The student will be exposed to academic, pharmaceutical and commercial environments providing a good platform for career development.
