Reprogramming the oocyte

(Phys.org)—Among other things, the egg is optimized to process the sperm genome. The cytoplasmic factors that make this possible also give the egg the ability to reprogram the nuclei from other kinds of cells if these nuclei ...

Study uncovers the secrets of plant regeneration

Plants have the unique ability to regenerate entirely from a somatic cell, i.e., an ordinary cell that does not typically participate in reproduction. This process involves the de novo (or new) formation of a shoot apical ...

Lost frog DNA revived

As part of a "Lazarus Project" to try to bring the Australian gastric-brooding frog back from extinction a UNSW-led team has succeeded in producing early stage cloned embryos containing the DNA of the frog, which died out ...

Cause of oversized placentas in cloning found after two decades

One reason a technique for cloning animals often results in oversized placentas, and hence failed births, has been uncovered in mice by an all-RIKEN team. This finding will help improve the success rate of the cloning method ...

Researchers succeed in making generations of mouse clones

Using the technique that created Dolly the sheep, researchers from the RIKEN Center for Developmental Biology in Kobe, Japan have identified a way to produce healthy mouse clones that live a normal lifespan and can be sequentially ...
