They create photosynthetic skin that can regenerate human tissue


Chilean scientist Tomas Egana presented the study with which he created the first version photosynthetic skin, which produces and releases oxygen, and that can regenerate the tissue human

In a presentation at the Catholic University of Chile, Egana, Ph.D. in Human Biology and Pharmacology, he explained that after eight years of animal testing (rats, pigs and fish), first clinical trial in a hospital in Salvador, Santiago, with twenty patients who suffered trauma.

"This step, which will last six months, is small but very important to demonstrate the safety of technology, if we can make it safe, we can apply it to other types of patients and diseases, such as transplantation of organs and cancer patients"said Egana in a statement to Efe.

This research, carried out at the Catholic University of Chile, developed the first skin transplant technique through the implantation of genetically modified microalgae for the production of oxygen and thereby regenerate the area.

"90% the cells of our body They are not human. The human body is a true ecosystem where coagulants are microorganisms and cell cells. What we want to find out is what happens in the body if I implant microalgae that produce photosynthesis, "Egana said during the presentation.

Photosynthesis is a process that processes plants when they break water molecules, with the energy of light, and release oxygen that consumes all living beings on the planet, said a Chilean scientist.

"The big question is what can we do if people can reproduce this process in a therapeutic context, because there are many diseases caused by oxygen deficiency such as bleeding, heart attack, or big wounds that do not cure," Egana added.

The first line of research focuses on the possible application of this technique in wounds to oxygenate them through creams, bandages or seams that contain microorganisms that carry photosynthesis.

While the second line explores the use of this technology in organ transplantation, to ensure that organs live longer outside the body and oncological therapy in order to achieve greater elimination of cancer cells.

At the beginning of the research at the University of Lubeck, Germany, where Egana was awarded a doctorate, he successfully developed a test that injected fish embryos, some microalgae and successfully managed to connect "without algae, they will kill the embryo and embryos that will kill algae."

As the researcher pointed out today, the key to this first clinical trial would be to avoid patients rejection of these transplants.

In case that twenty patients successfully transplant the skin, the idea is that, when the skin regenerates, the implant is removed by the same body or removed.

In this sense, the next six months will be necessary to determine the possibility of applying this technique in the future of medicine. EFE
