Chile scientist creates photosynthetic skin that regenerates tissues


The scientist from Chile, Tomás Egaña, presented yesterday the research that he has created the first version of photosynthetic skin, which produces and releases oxygen, which will be able to regenerate human tissue.

In the presentation at the Chilean Catholic University, Egaña, a PhD in Human Biology and Pharmacology, explained that after the eight years of analysis and testing with animals (mice, pigs and fish), the first clinical trial at El Salvador Hospital, in Santiago, with 20 of patients suffering from trauma.

"This step, which lasts six months, will be small but very important to show the security of the technology. If we can do it safely, we can do it to other types of patients and diseases, such as organ transplants and cancer patients, "said Egaña in statements.

This research, carried out at the Chilean RC, has developed a first technique to make a skin transplant by embedding genetically modified microalgae to produce oxygen and regeneration and the area.

"90% of cells in our body are not human. The human body is a true ecosystem where microorganisms and human cells are in keeping together. What we want to find is what, 39, occurs in the body if we implant microalgae that produce photosynthesis, "said Egaña during the presentation.

Photosynthesis is the process made by plants when they break water molecules, with light energy, and release the oxygen that everyone who lives on the planet eats, says # 39 ; The scientist from Chile.

"The big question is what we can achieve if people could reproduce this process in a therapeutic context, because many diseases are caused by a lack of oxygen such as hemorrhage, heart attack, or wounds big ones that do not improve, "added Egaña.

The first line of the investigation focuses on the potential applications of this wound technique to oxygenate through creams, bandages or lines that contain micro-organisms that perform photosynthesis.

Although the second line is investigating the application of this technology in organ transplantation, to ensure that organs live longer than the body, and in oncological therapies to get eliminate cancer cells better.

At the beginning of the research at Lübeck University, in Germany, where he was awarded a doctorate to Egaña, he successfully developed a test where he sprayed fish embryo, some microalgae, and successfully combined "without algae, they kill the embryo and without embryo killing the algae. "


Avoid refusing. As emphasized by researcher Tomás Egaña, the key to this first clinical trial will be precisely in order to avoid refusing patients to these transplants.

Remove the implant. If the 20 patients get the skin transplant successfully, the idea is that when the skin is regenerated, it is removed by the same body or removed.

Action The next six months will be essential to determine the possible operation of this technique in the future of medicine.
