The proliferation and differentiation of a stem cell are regulated intrinsically by the extrinsically niche. Elucidation regulatory mechanisms spermatogonial cells (SSCs), postnatal male germ line, would be facilitated in vitro studies that provide defined microenvironment reconstituted ex vivo. We analyzed effect environment on maintenance adult immature SSCs 7-day culture system. Allthough number decreased time-dependent manner, nearly one four (24%) could maintained for 7 days. Stem was...
Male germ-line stem cells are the only cell type in postnatal mammals that have capability to self-renew and contribute genes next generation. Genetic modification of these would provide an opportunity study biology their complex self-renewal differentiation processes, as well enable generation transgenic animals a wide range species. Although retroviral vectors been used efficient method introduce into variety types, male seemed refractory direct infection by viruses. In addition,...
Spermatogenesis occurs within the seminiferous tubules of mammals by a complex process that is highly organized, extremely efficient and very productive. At foundation this spermatogonial stem cell capable both self-renewal production progeny cells, which undergo differentiation over period weeks to months in order generate mature spermatozoa. It had been thought germ cells survive only brief culture, generally less than few weeks. However, an accurate assessment presence any population has...
Spermatogonial transplantation provides access to the mammalian germline and has been used in experimental animal models study stem cell/niche biology development, restore fertility, produce transgenic models. The potential manipulate and/or transplant numerous practical applications that transcend species boundaries. To make technology more broadly accessible, it is necessary develop recipient preparation protocols. In current study, mouse recipients for spermatogonial were prepared by...
To present retrograde target vessel catheterization as a bailout technique in fenestrated and branched endografting (F/B-EVAR).Between November 2003 2014, 11 (1.6%) of 671 consecutive patients with juxtarenal, suprarenal, thoracoabdominal aortic aneurysms required access measure during F/B-EVAR due to failure an antegrade approach. The vessels involved the left renal artery (LRA) 6 patients, celiac (CA) 3 right (RRA) 1 patient, both arteries patient.The were successfully catheterized secured...
