Apoptosis

Apoptosis is a phenomenon of programmed cell suicide highly conserved in living things. It has a central role in the development of both single-celled organisms as multicellular. Throughout the life of a living being, from the embryo to the adult organism, millions of cell deaths directed in some certain cells die without activating the mechanisms of response to wounds or leaving any marks apparent occur. Therefore, apoptosis is not a random and uncontrolled cell death is an active process, well defined genetically in which cells are destined to die concrete signals at a given time. During apoptosis complete structures (the membrane between the fingers in embryos) are removed, it shapes tissues and cell number determined. That is why it is a process well studied in animals, especially in the nervous system which determines the number of neurons.

Macrobiotus, is a tardigrade. Animal slow movements is what this name and today this tardigrade moves more slowly than usual. The reason is obvious, Macrobiotus lives encased in an elastic suit, his cuticle, and protect females when putting make below this elastic mesh that gives of himself to the absolute limits dragging the burden of fifteen lives

The theme stem cells has become, in recent years, very often in the media and has been the subject of heated debates in academic circles and among the general public. This is due to the promise that has been disclosed that these cells could be used to treat diseases that are considered incurable or chronic and degenerative diseases for which we currently have no way to treat with conventional methods available.
