Genetic and cellular analysis of male germ cell development.
The evolution of the germline has been studied for many decades. Although the pathway of germ cell primordial migration and the kinetic evolution of the gonocytes are well known, their genetic and cellular controls are poorly understood. Recently, a genetic approach using gene knockout and a cellular investigation using several germ cell culture models has allowed a better understanding of the involvement of several genes and factors in the development of germ cells during fetal and neonatal life. Because of the obvious importance of the development of primordial germ cells and gonocytes in adult fertility and its eventual alteration by toxins or xenobiotics, a better knowledge of these interactions appears as an important research area.
