Developmental biology of neural tube defects
In the Neural Development Unit we are investigating the genetic, molecular and cellular basis of central nervous system development with particular reference to clinically important congenital malformations. Our previous work has succeeded in defining several steps in the embryonic pathway of neurulation, and has permitted a neural tube defect, spina bifida, to be prevented by a new method complementary to folic acid. Close links with Great Ormond Street Hospital for Children allow research findings to be applied to the clinical situation.

Embryonic mechanisms underlying neural tube defects in mouse genetic models
The purpose is to identify the molecular mechanisms that become
disrupted in the Zic2 mutant mouse which develops severe spina bifida
as a result of defective neural plate bending during neurulation.
Techniques will include immunohistochemistry and in situ hybridisation
on whole and sectioned mouse embryos. The lab makes extensive use of
whole mouse embryo culture, a technique by which mouse embryos can be
cultured intact during neurulation and subjected to a variety of
experimental techniques (e.g. gene electroporation). A placement in
the lab will provide an opportunity to gain experience of this powerful
technique for analysing the developmental events during mammalian
embryogenesis.
