In addition, it is intended to be applied to 'in vitro' tests of drugs and the study of diseases such as diabetic retinopathy, a disease whose causes and evolution are not yet well defined. microchip retina José Yeste , lead author of the study and scientist at the Higher Council for Scientific Research (CSIC) , points out that these cells form the internal part of the barrier , being in contact with the blood capillaries, through which oxygen and oxygen reaches the retina. nutrients. In addition, the microdevice is also made up of neuronal cells that make up the neuroretina and cells that make up the outer layer. The cells are connected to each other through a network of microgrooves , which allows the exchange of information, so they can send their signals to each other and interact in a similar way to how they would in a living organism.

Scientists have evaluated the correct formation of the blood-retinal barrier by performing permeability and electrical resistance tests, as well as the expression of tight junction proteins between cells. With this microdevice it is possible to investigate the effects of different molecules or various damages on the human retina. Sea Graduate in Audiovisual Communication UK Mobile Number List and Master in Radio and Television Journalism. She is a writer in various media and undertaking new challenges as a Community Manager. She is now at . read all my articles "Molecular scissors also fight cancer marisol pena marisol the University of Pennsylvania is going to start a study focused on the treatment of various types of cancer using the. World Cancer Day was celebrated on February.



A disease that has new cases in Spain each year . While globally it ranks as the second cause of death , according to the World Health Organization . The molecular scissors technique wants to do magic again, but this time with cancer. The CRISPR-Cas9 system serves to “cut” and “paste” DNA quickly, precisely and efficiently. Research from Harvard University was able to stop a type of deafness in mice using this method. Although this tool is no longer limited to laboratory animals or plants. In October 2016, molecular scissors were first used in humans . A study by Sichuan University and West China Hospital succeeded in introducing modified cells into a patient with aggressive lung cancer . Now, the United States joins the Asian giant in the fight against the development of cancer.
