What Does tissue Mean
Two major meanings are attributed to the notion of fabric : one related to fashion and the textile industry, and the other associated with biology .
A fabric can therefore be a product that someone made by weaving (that is, weaving threads, cords, etc., to form fabrics). For example: “This fabric has sheep's wool and organic cotton” , “I want to buy a knitted sweater so as not to get so cold next winter” .
This class of fabrics can be flat (twill, satin or taffeta) or knitted (both warp and weft). Some of the most common fabrics internationally are silk, linen, wool and cotton.
Fabric is also used to refer to the texture of a certain fabric : “I don't like the weave of this fabric , although the color is very attractive” , “I want a fabric that is soft to the touch” .
For biology, anatomy, zoology and botany, a tissue is formed from the different aggregates of cells of the same class but differentiated in a certain way and arranged in a regular way. The cells of a tissue work together, en bloc, to fulfill a specific role.
Animals have four basic tissues: the muscle tissue , the nerve tissue , the epithelial tissue and connective tissue . In the case of muscle tissue, it must be said that it is made up of muscle fibers and that it accounts for between 40 and 45 percent of man's mass . People and animals move thanks to this tissue, whose cells are highly specialized.
Stem cells and tissue reconstruction
A large part of the tissues of our body has a certain number of stem cells, whose function is to regenerate in case of damage . Despite this, when conditions of considerable volume occur, its action is not enough. And this is the point at which a technique that has been in research and development for some time could mark a before and after in world medicine . It is about providing the compromised tissues with more stem cells than they naturally possess, and the objective is to achieve the reconstruction of whole organs, with the consequent reduction in the percentage of transplants that are performed every year.
The primary targets are the heart, lungs, and liver, and complete regeneration of both tissue and function is promised . To support these promises, there is evidence of interventions that have succeeded in reconstructing parts of the esophagus, the trachea, and the musculature attached to the skeleton of people and animals.
Basically, this process is based on the fact that stem cells do not have a particular function and even when they are extracted from a tissue, they do not lose the ability to divide to transform into new cells, conserving their properties .
Unlike cloning, this practice does not raise the same ethical questions , although it does feed that human need not to die until it is absolutely necessary, to cure those diseases from which other living beings die and respect the cycle of life. that form part of. The reconstruction of tissues with external stem cells is certainly less violent than a transplant, and if one takes into account that this last type of intervention takes place more than one hundred thousand times a year worldwide (not counting the people who cannot achieve the organ they need) this discovery cannot be considered negative, since it would offer all these patients the same possibilities.
