The origin and development of the spermatogenic cell lineage is reviewed, as well as
spermatogonial kinetics in adult nonprimate mammals in relation to the cycle of the …

The mammalian seminiferous epithelium consists of a highly complex yet well-organized
cell population, with germ cells in mitosis and meiosis and postmeiotic cells undergoing …

抄録< jats: title> Abstract</jats: title>< jats: p> Spermatogonial stem cells are responsible for
the maintenance of spermatogenesis in the adult mammal. Knowledge of their regulation is …

Spermatogenesis in the mouse has been investigated by counting the different kinds of
spermatogonia throughout the cycle of the seminiferous epithelium. A description is given of …

Recent studies by Brinster and col-leagues reported in this issue of theProceedings (1, 2)
have shown that the in-jection of spermatogonial stem cells into the testes of sterile recipient …

Initiation of the first wave of spermatogenesis in the neonatal mouse testis is characterized
by the differentiation of a transient population of germ cells called gonocytes found in the …

Through the use of donor cells from transgenic rats expressing GFP exclusively in the
germline, we have defined culture conditions where male germ cells lose (on STO cells) or …

Whole mounted segments of seminiferous tubules from rat testes have been used to
investigate the morphology and proliferative activity of the undifferentiated type A …

The continuation of the spermatogenic process throughout life relies on a proper regulation
of self‐renewal and differentiation of the spermatogonial stem cells. These are single cells …

Spermatogenesis is a complex and tightly regulated process during which successive
mitotic and meiotic divisions finally lead to the production of differentiated spermatozoa …
