In future Humans may be able to self-heal heart cells.

“Scientists have discovered genetic interactions that may allow heart cells to regenerate, an advance that could lead to new therapies to treat cardiac diseases”.

  • Researchers from the University of Florida in the U.S. found genes known to form hearts cells in the gut of a muscle-less and heart-less sea anemone.

Sea anemones : These are a group of water-dwelling, predatory animals of the order Actiniaria. They are named for the anemone, a terrestrial flower. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia.

The Discovery

  • The sea anemone can regenerate into a new animal if it is cut into many pieces. Researchers analysed the function of its “heart genes” and discovered a difference in the way these genes interact with one another, which may help explain its ability to regenerate
  • If Scientists learn more about the logic of how genes that give rise to heart cells talk to each other, muscle regeneration in humans might be possible.

Logic Behind It

  • The heart genes generate what engineers call lockdown loops in vertebrates and flies, which means that once the genes are turned on, they tell each other to stay on in an animal’s cells for its entire lifetime. Animals with a lockdown on their genes cannot grow new heart parts or use those cells for other functions.
  • In sea anemone embryos, the lockdown loops do not exist, That’s why there gene can generate new cell.

Gene

  • A unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

Cardiac Muscle

  • It is  an involuntary, striated muscle that is found in the walls and histological foundation of the heart, specifically the myocardium. Cardiac muscle is one of three major types of muscle, the others being skeletal and smoothmuscle.
