Testis histostructrure dynamics during quail (Coturnix coturnix) spermatogenesis

Male sex cells are unique objects for scientific research in the field of genetics and physiology and in the study of the development biological basis in animal husbandry. Maturation and differentiation processes in male animals and birds germ cells are of great interest for comparative embryology, developmental biology, medicine and biotechnology. Quails characterized by early puberty and a short generation period are perspective for these experimental works. The greatest interest is the use of spermatogonia, the testes stem cells which are currently being actively studied as promising targets for the introduction of recombinant DNA in obtaining transgenic individuals. However, the morphology of germ cells from male poultry in their formation process is not fully covered. For the first time, we describe in detail the histological features of spermatogenical quail epithelium tissue at different stages of spermatogenesis and the dynamics of spermatogonial testis cells populations in this study...
