A fabric is a textile product obtained by interweaving threads or other similar elements.
The notion of fabric is attributed two major meanings: one related to fashion and the textile industry , and another associated with biology .
A fabric can therefore be a product that someone made by weaving (i.e., interlacing 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 I won't be so cold next winter” .
This type of fabric can be plain (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 particular 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" .
Tissue in biology
In biology, anatomy, zoology and botany, a tissue is formed from different aggregates of cells of the same kind but differentiated in a certain way and arranged in a regular manner. The cells of a tissue work together, as a block, to fulfill a specific role.
Animals have four basic tissues: muscle tissue , nervous tissue , epithelial tissue and connective tissue . Muscle tissue is composed of muscle fibres and accounts for 40 to 45 percent of a person 's body mass. People and animals move thanks to this tissue, whose cells are highly specialised.
In biology, a tissue is a set of different cells that are organized and work together.
Reconstruction from stem cells
Most of the tissues in our body have a certain number of stem cells, whose function is to regenerate in the event of damage . However, when a significant amount of damage occurs, their action is not sufficient. 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 involves providing the affected tissues with more stem cells than they naturally possess, and the aim is to achieve the reconstruction of entire organs, with the consequent reduction in the percentage of transplants carried out every year.
The primary targets are the heart, lungs and liver , with promises of complete regeneration of both tissue and function . Supporting these promises is evidence of interventions that have successfully reconstructed parts of the esophagus, trachea and musculature attached to the skeleton of humans 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, retaining their properties .
Cloning and tissues
Unlike cloning, this practice does not raise the same ethical questions, although it does feed the human need to not die until it is absolutely necessary, to cure those diseases from which other living beings die and respect the cycle of which they are a part.
The reconstruction of tissue with external stem cells is certainly less violent than a transplant, and if we take into account that this last type of intervention takes place more than one hundred thousand times a year worldwide (not counting the people who are unable to obtain the organ they need), this discovery cannot be considered negative, since it would offer all these patients the same possibilities.
