Dr. Annemiek Beverdam studies the genetic processes that govern development, homeostasis and regeneration of the skin in the mouse. Her research aims at understanding the genetic and molecular basis of developmental and human regenerative skin diseases such as skin cancer, which affects 2 out of 3 Australians in their life time. Her lab recently made the pivotal discoveries that Yes-associated protein (YAP) functions acts as a key molecular switch in epidermal stem/progenitor cell proliferation and differentiation [https://www.ncbi.nlm.nih.gov/pubmed/23190885] by driving β-Catenin Activation [https://www.ncbi.nlm.nih.gov/pubmed/27816394]. Dr. Beverdam currently investigates the developmental genetic context in which YAP functions to control skin stem/progenitor cells in normal and in disrupted skin biology. She employs genetically manipulated mouse models, human skin samples, advanced imaging technology such as confocal microscopy and whole mouse in vivo imaging, gene and protein expression analyses and whole genome approaches to address her research questions. Her research will open up exciting new avenues for translational research and the development of treatments for human regenerative skin disease such as skin cancer and eczema.

The genital system is closely linked developmentally to the urinary system, often called the urogenital system. This practical will therefore cover early development of both system.
 
 
 
In understanding embryonic sexual development, think of a cascade of sequence dependent events that transform indifferent gonads, internal and external genitalia into distinct male and female structures.
 
 
 
The process begins with gonad differentiation, which itself is tied developmentally back at the initial event of fertilization and the presence of either a Y or X chromosome in the sperm.
 
 
 
The endpoint of development could be considered the post-puberty active reproductive system. Interestingly, recent research is pointing to a link between neural and reproductive systems in how male and female brains may differentially develop under the influence of sex hormones and perhaps even the sex chromosomes.
