The effect of temperature on the initial development of Brycon amazonicus Spix & Agassiz, 1829 as tool for micromanipulation of embryos
(2017-09-20)
Primordial germ cell (PGC) transplant is a promising tool in aquaculture; however, successful use of this technique requires in depth knowledge of the early stages of embryo and larval development. The aim of this study ...
Transplante interespecífico de células germinativas-tronco em Siluriformes Neotropicais
(Universidade Estadual Paulista (Unesp), 2018-02-27)
No Brasil os siluriformes neotropicais são o segundo grupo mais ameaçado de extinção com 91 espécies. Neste trabalho, foi empregada a técnica de quimerismo usando duas espécies de siluriformes neotropicais o mandi (Pimelodus ...
The effects of temperature and busulfan (Myleran) on the yellowtail tetra Astyanax altiparanae (Pisces, Characiformes) spermatogenesis
(Elsevier B. V., 2015-10-01)
We aimed to standardize a protocol to suppress spermatogenesis in the characiform fish, Astyanax altiparanae, for future use as a host in germ cell transplant research, opening opportunities for a range of studies, such ...
Germ Cell Transplantation in Felids: A Potential Approach to Preserving Endangered Species
(Amer Soc Andrology, Inc, 2012-03-01)
With the exception of the domestic cat, all members of the family Felidae are considered either endangered or threatened. Although not yet used for this purpose, spermatogonial stem cell (SSC) transplantation has a high ...

Triploid or hybrid tetra: Which is the ideal sterile host for surrogate technology?
(2018-03-01)
This work was aimed at developing an effective procedure to obtain sterile ideal host fish in mass scale with no endogenous germ cells in the germinal epithelium, owning permanent stem-cell niches able to be colonized by ...
Spermatogonial Stem Cells in Fish: Characterization, Isolation, Enrichment, and Recent Advances of In Vitro Culture Systems
(Mdpi, 2020-04-01)
Spermatogenesis is a continuous and dynamic developmental process, in which a single diploid spermatogonial stem cell (SSC) proliferates and differentiates to form a mature spermatozoon. Herein, we summarize the accumulated ...
