Sperm and egg cells, or gametes, are unusual. Egg cells are some of the largest cell types, and sperm are some of the smallest. In humans, these haploid cells come together to form diploid cells. It's ...

"In creating a more stressful replication environment at the site of ALT telomeres, cellular reproduction was halted, leading us to believe that there could be great potential for these novel ...

A functional sperm tail is essential for successful reproduction. Defects in its development often lead to infertility. This ...

SCOTTSDALE, Ariz. (Jan. 12, 2010) – A new investigational drug designed to stop cancer cells from reproducing may offer hope for patients with advanced solid tumor cancers. Clinical trials of TKM-PLK1 ...

THE investigations described in this volume were undertaken with the view of supporting the theory of H. C. Ross, that cell-reproduction is brought about by certain chemical agents termed “auxetics,” ...
