The fish heart will cure the human. ...

The tiny aquarian small fish can help to "repair" to people the damaged hearts. Scientists have established, that when this fish loses a warm muscular tissue thus especially is not upset. Because at once grows up to itself new.
Danio rerio - one of the most popular aquarian fishes represents ideal model for search of new ways of restoration of the damaged human hearts as scientists consider. When a part of its heart it is irreversible it is damaged and disappears, the small fish stays in a "lethargic" condition of all some days, and then again becomes healthy.

For this term in an organism Danio rerio there are present miracles - heart itself grows up a missing tissue, there is a heart neogenesis. It is reached at the expense of warm muscular cells named cardiomyocytes. It not stem, and the mature differentiated cells which usually provide contractile ability of heart.

"Our research proves, that Mother Nature uses also other ways of neogenesis of the damaged tissues and organs, besides pluripotent stem cells", - the professor of gene laboratory speaks at Institute of biological researches in California doctor Juan Carlos Belmonte.

To a stage of refusal of heart the damaged cells of a cardiac muscle at mammals enter a winter sleep stage (cellular anabiosis) in which they cease to be reduced in attempt to survive. The winter sleep of warm cells of mammals is very important, as the author of research Chris Dzhoplin considers. Together with colleagues he has found out, that during neogenesis of heart at Danio rerio cardiomyocytes showed the structural changes similar to what were observed at cardiomyocytes of mammals in a winter sleep condition.

Scientists believe, that the cardiomyocytes of mammals which are passing through a winter sleep, can represent cells which try to breed. Probably, only it is necessary to push them in the necessary direction and then human hearts too to learn to regenerate a muscular tissue not worse aquarian small fishes
