The spermatogonial stem cell: from basic knowledge to transgenic technology.
Abstract
Differentiation of germ cells in the testis originates from a constantly renewed small pool of stem cells. They give rise to the first differentiated spermatogenic cells (spermatogonia). These committed cells will then follow a strictly defined succession of steps, starting with six synchronized mitotic cycles before reaching the first meiotic stages. Following a first identification of the spermatogonial stem cells on morphological and cytological criteria, a functional assay was devised, based on their ability to repopulate the testis of a sterile recipient. Purification and characterization of the stem fraction is in progress. Fundamental knowledge of the biology of the germ line and preclinical studies in several important fields will benefit of these advances, while gene transfer prior to reimplantation opens a new approach in transgenic technology.
