This cell contained all the information to create an adult made of trillions of cells. We know that the egg does not provide centrioles, so the origin of all the centrioles in our body is from the sperm bio lab report the father. However the sperm have only one centriole, so where does the second centriole come from?
Ciliogenesis: During my postdoctoral research in the lab of Charles Zuker in the University of California, I studied the mechanism of cilia formation. To identify the genes required for cilia formation, I have developed a novel bioinformatic screen and found a large collection of genes required for cilia formation. Cep152 is a key regulator in the initiation of centriole duplication. Before our publication, for nearly ten years, it was believed that Asterless was only essential for the function of the mature centrosome. The major goal of this project is to study develop a rabbit expressing POC1-Neon to study the role of sperm centrioles. The major goal of this project is to study the mechanism of pericentriolar material assembly during centrosome biogenesis in Drosophila melanogaster. The major goal of this project is to identify the commercial need for male factor infertility test.
