Developmental Physiology Laboratory
Lab head: Margot Day
Location: K25 - Medical Foundation Building
Research conducted by this laboratory is related to the cellular processes occurring during development of the embryo before implantation, including fertilisation, cell division and cell differentiation. In particular, this laboratory is studying the regulation of ion channels during development and whether they are involved in progression of the cell cycle. This laboratory has recently demonstrated the existence of a novel cell cycle clock, in early embryos, which functions independently of the nucleus. This laboratory is currently investigating the intracellular signalling pathways involved in regulation of this clock and how it is linked to the nuclear cell cycle. This laboratory uses techniques such as patch-clamping, molecular biology and methods for studying protein expression.

Impact of growth factors on early embryo development in vitro
Primary supervisor: Margot Day
Maternally-derived factors are absent during embryo culture and embryo-derived factors are often inactive because of sub-optimal culture conditions. This project will investigate which factors improve embryo development following IVF and culture. It will also investigate the intracellular signalling pathways utilised by these factors.
Research in the laboratory utilizes a number of techniques including mouse embryo culture, fluorescent measurement of intracellular ions, patch-clamping and molecular biology.
