Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

Researchers have shown for the first time how Merkel cell polyomavirus (MCV), which causes an aggressive skin cancer called Merkel cell carcinoma, initiates DNA replication in host cells. University ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

A new, nano-scale look at how the SARS-CoV-2 virus replicates in cells may offer greater precision in drug development, a Stanford University team reports in Nature Communications. Using advanced ...
