This review looks into the phylogeny of spermatogonial stem cells and describes their basic
biological features. We are focusing on species-specific differences of spermatogonial stem …

BACKGROUND Advances in stem cell research have opened new perspectives for
regenerative and reproductive medicine. Stem cells (SC) can differentiate under appropriate …

Embryonic germ cells as well as germline stem cells from neonatal mouse testis are
pluripotent and have differentiation potential similar to embryonic stem cells,, suggesting that …

Male gametes originate from a small population of spermatogonial stem cells (SSCs). These
cells are believed to divide infinitely and to support spermatogenesis throughout life in the …

Recent studies have demonstrated that somatic stem cells have a more flexible potential
than expected, whether put into tissue or cultured under different conditions. Bone marrow …

We have generated a transgenic mouse line, Tg (Stra8‐cre) 1Reb (Stra8‐cre), which
expresses improved Cre recombinase under the control of a 1.4 Kb promoter region of the …

Previous reports and the current study have found that germ cell precursor cells appear in
embryoid bodies (EBs) formed from mouse embryonic stem cells as identified by positive …

The long-term production of billions of spermatozoa relies on the regulated proliferation and
differentiation of spermatogonial stem cells (SSCs). To date only a few factors are known to …

Background: There is a rapidly growing trend in the consumption of herbal remedies in the
developing countries. The Phoenix dactylifera DATE PALM POLLEN (DPP) is used in the …

The recent reports on the treatment of azoospermia patients, in which spermatozoa could
not be traced in their testes, are focused more on the potential use of adult stem cells, like …
