Although embryonic stem cells (ESCs) have been successfully derived from mice and rats, efforts to establish chimeric and germline-competent ESC lines in species beyond rodents have been unsuccessful.

Egg whites may be perfect for a health-conscious breakfast, but egg yolks turned out to be the key ingredient for cultivating bird embryonic stem cells (ESCs) in the lab. Using a growing medium of egg ...

Early embryogenesis is characterized by dramatic cell proliferation and movement. In most insects, early embryogenesis includes a phase called the uniform blastoderm, during which cells evenly cover ...

The world is full of birds – chirping, fluttering, waddling; feathered, beaked, and clawed. These wonderfully diverse animals, the closest living descendants of the magnificent dinosaurs, have ...

Researchers have developed a method for culturing fertilized chick eggs without their shells. The eggs were placed in an artificial culture vessel made of transparent film, allowing for real-time ...

Researchers at University of Tsukuba, have developed a method for culturing fertilized chick eggs without their shells. The eggs were placed in an artificial culture vessel made of transparent film, ...

The process of embryogenesis begins when an egg or ovum is fertilized by a sperm cell to form a zygote. This zygote then undergoes mitotic division, a process that does not result in any significant ...

Peer ReviewDownload a summary of the editorial decision process including editorial decision letters, reviewer comments and author responses to feedback. Mitotic centrosomes are formed when centrioles ...

Nesprins (Nuclear Envelope SPectrin Repeat proteINS) are outer nuclear membrane resident macromolecules that constitute the LINC (LInker of the Nucleoskeleton and Cytoskeleton) complex (Zhang et al., ...

The fish species Astyanax mexicanus with its sighted and blind eco-morphotypes has become an original model to challenge vertebrate developmental evolution. Recently, we demonstrated that phenotypic ...

Current methods for CRISPR/Cas9-mediated gene knockout in avian species require isolation, culture, and genome modification of primordial germ cells in vitro for the subsequent injection into the ...
