What is cell regeneration?

cell regeneration is a biological feature of all living organisms from bacteria to plants and amphibians to mammals. It is an act of restoration, growth or restoration of cells involved in maturation, wound healing, tissue repair and similar biological functions. Cell regeneration in its most extreme form is what allows starry, flat worms and lizards to re -grow broken limbs, tails or in the case of flat worms, clone the entire structure of the body for reproduction. People have certain limited capabilities of cellular regeneration regeneration that allow you to replace worn or damaged tissues. Maintaining the biological integrity of the organism is the primary purpose of cell regeneration, although some organisms also use cell regeneration as a form of asexual reproduction. For example, yeasts spread and repair the O unhrough asexual process of cell regeneration known as cellular hopes. The new cell grows like a Nub attached to the old cell and collects information about DNA for reproduction of accurate duplicate cells. AfterThe new cell tears and becomes independent of its host cell, allowing yeasts and similar mushrooms to reproduce, grow or repair damage.

Some reptiles and amphibians have the ability to comprehensive cellular regeneration, allowing the entire tissue structures to turn after damage to the process known as autotomy. When there is an injury or such creatures are endangered by predators, adult cells in the tail, fins and other pendants can separate from the main body, leaving the pendant behind. Within the natural biochemical process of creation, cells on the edges of such injuries turn back into stem cells, allowing cell regeneration identical to initial growth and the development of the lost attachment.

In humans, cell regeneration represents a slightly different process. Stem cells, generic cellular building blocks that allow embryo to eventually form specificOrgans, tissues and pendants are present only in vitro. As the cells develop into ripe cells, they cannot return to stem cells, as seen in some reptiles and amphibians. Mature brain cells, skin cells, nerve cells and other cell classifications can only be divided and reproduced as cells, limiting cell regeneration in humans.

While limited cell regeneration in humans plays an important role in the development, healing and repair of tissues. Bugs in humans naturally die at billions of a day due to necrosis, cell death due to damage or damage or apoptosis. Apoptosis is a form of programmed cell death that allows cells to fragment or otherwise die in the normal biochemical process involved in development, growth, and aging. Without any form of cell regeneration, necrosis and apoptosis would eventually lead to the destruction of whole organs and tissue areas. Instead, cell regeneration allows the body to grow new cells to replace dead, die or otherwise damagesno cells by dividing a single healthy cell into two separate cells.

Although people retain the ability to regenerate cells under certain conditions, the ability to completely regenerate the entire structure is limited to certain tissues and organs such as liver and skin. For example, brain cells are slowly regenerating over time, but one could not grow a new brain through cell regeneration. Alternatively, the human body can regenerate the liver, provided at least a quarter of the organ remain intact. Similarly, the skin can be again again to cover large areas of damage, provided there is a sufficient percentage of the skin from which new cells can be replicated.
