Oxidative stress, generated by excessive reactive oxygen species (ROS) or decreased
antioxidant defenses (and possibly both), is associated with male infertility. Oxidative stress …

Abstract In the United States, poultry genetic resources have consolidated because of
economic pressures. Such consolidations can potentially jeopardize the poultry industry and …

Transgenic birds embody one of the most potent and exciting research tools in
biotechnology for agriculture, medicine, and model animals. To date, retrovirus-or lentivirus …

Background Long-term maintenance of avian primordial germ cells (PGCs) in vitro has
tremendous potential because it can be used to deepen our understanding of the biology of …

Chickens have proven to be useful organisms for transgenic research. This work provides
enormous benefits in advancing animal biotechnology and aids in the development of …

Advances in genome-editing technologies and sequencing of animal genomes enable
researchers to generate genome-edited (GE) livestock as valuable animal models that …

Germ cells are the only cell type capable of transmitting genetic information to the next
generation. During development, they are set aside from all somatic cells of the embryo. In …

As in other vertebrates, avian testes are the site of spermatogenesis and androgen
production. The paired testes of birds differentiate during embryogenesis, first marked by the …

This study was undertaken to develop novel markers for chicken primordial germ cells
(PGCs), which are of potentially enormous value in transgenic research. Gonadal cells …

The majority of poultry genetic resources are maintained in situ in living populations.
However, in situ conservation of poultry genetic resources always carries the risk of loss …
