Possessing two X chromosomes can significantly reduce DNA methylation in mouse embryonic stem cells, potentially explaining why such cell lines have proven unstable in culture, scientists report ...

Most mammals, including humans, have two sex chromosomes, X and Y. One sex chromosome is usually inherited from each parent, and they pair up as either XX or XY in every cell of the body. People with ...

Sanford-Burnham scientists developed a way to expand these cells without risking uncontrolled replication. Human embryonic stem cells (hESCs) may take a back seat to human somatic progenitor cells for ...

Researchers have developed a new technique for creating human embryonic stem cells by fusing adult somatic cells with embryonic stem cells. The fusion causes the adult cells to undergo genetic ...

As species continue to face massive extinction, preserving genetic material through judicious biobanking to enable cloning is key to promoting the survival of species and maintaining biodiversity.

A regulatory pathway that changes the way cells divide in plants has been discovered by a team of researchers. An international scientific consortium including the Freiburg plant biologist Prof. Dr.
