CHILE .- The Chilean scientist Tomás Egaña today presented the research with which he created the first version of photosynthetic skin, which produces and releases oxygen, and which will be in able to regenerate human tissue.
Egaña, doctor of human biology and pharmacology of the Catholic University of Chile, explained that after eight years of badyzes and tests on animals (rats, pigs and fish), the first clinical trial at the Hospital of Salvador de Santiago patients who suffered trauma.
"This step, which will last six months, is small but very important to demonstrate the safety of the technology.If we can make it safe, we can apply it to other types of patients and patients. diseases, such as organ transplants and cancer patients, "Egaña told Efe.
This research, carried out at the Catholic University of Chile, was developed a first technique to perform a skin graft by implantation of genetically modified microalgae in order to produce oxygen and thus regenerate the region.
"90% of our body's cells are not human The human body is a real ecosystem where microorganisms and human cells coexist What we want to know is what happens in the body if we plant microalgae that produce photosynthesis, "Egaña said during the presentation.
Photosynthesis is the process that plants perform when they break water molecules, with the energy of light, and release the oxygen that is consumed by all living things on the planet. Chilean scientist.
"The big question is what can we do if man succeeds in reproducing this process in a therapeutic context, because many diseases are caused due to lack of oxygen such as blood pressure? hemorrhage, infarction or large wounds that do not heal, "added Egaña.
The first line of research deals with possible applications of this technique in wounds to oxygenate them through creams, bandages or sutures containing microorganisms that perform photosynthesis.
While the second line examines the application of this techno in organ transplants, in order to make organs live longer outside the body, and in oncological therapies to achieve greater elimination of cancer cells.
Early research at the University of Lübeck, Germany. , where Egaña got his doctorate, he managed to develop a test in which he injected a fish embryo, a micro-algae, and succeeded in its fusion "without the kelp killing the embryo and that the Embryo does not kill algae ".
As the researcher pointed out today, the key to this first clinical trial will be precisely to avoid the rejection of patients at these transplants.
If the twenty patients correctly receive the skin graft, the idea is that, when the skin is regenerated, the implant is removed from the same body or removed.
In this sense, the next six months will be essential in determining the possible implementation of your This technique will be used in the future of medicine.
