Research recently published by a Michigan State University scientist adds to the understanding of how mitochondria function during spermatogenesis, the process by which sperm cells are produced. Wang ...

Each sperm cell, or spermatozoon, is small and motile. The spermatozoon has a flagellum, which is a tail-shaped structure that allows the cell to propel and move. In contrast, each egg cell ...

Kanazawa University and colleagues have achieved a breakthrough in understanding sperm DNA packaging. Using high-speed atomic ...

There are many different types of cells in animals. Each type is specialised for a particular role. These ensure that the organism functions as a whole. The head of the sperm contains the genetic ...

These primordial germ cells are initially "bipotent"—able to become either sperm or eggs. But while the embryo is still snug in the womb, its bipotent cells commit to one path or another and ...

Could it be that one of only three known markers directly targeting the DNA does not exist outside the realm of microbes? Now ...

The chromosomes of sperm cells are tightly packaged ... a nucleohistone to a nucleoprotamine structure may serve both biophysical and developmental functions. Several recent genetic studies ...
