Una vez más el estudio de los animales viene en ayuda de los seres humanos. En esta ocasión, del mundo submarino: el pez cebra.
La capacidad de este pez para regenerar sus retinas dañadas se convirtió en un indicio sobre cómo reparar la visión humana, a tal punto que en cinco años podría estar desarrollado un tratamiento experimental para curar la ceguera.
Investigadores británicos del Instituto de Oftalmología del University College London lograron desarrollar en laboratorio un tipo de célula madre adulta que se encuentra en los ojos de los peces y en los mamíferos y que se convierte en las neuronas de la retina.
Estas células podrían inyectarse en los ojos como tratamiento para enfermedades como la degeneración macular, el glaucoma y la ceguera por diabetes, según la investigadora Astrid Limb.
El daño de la retina, la parte del ojo que envía mensajes al cerebro es responsable de la mayoría de los casos de pérdida de la visión.
Zebra fishes and blindness
Once again the study of animals comes in aid of the human beings. In this occasion, from the submarine world: the fish zebra.The capacity of this fish to regenerate its damaged retinas became an indication of how to repair the human vision, to such point that in five years could be developed an experimental treatment to cure some types of blindness.British investigators of the Institute of Ophtalmology of the University College London developed in laboratory a type of adult stem cell cell that is in the eyes of the fish and the mammals and that becomes the neurons of the retina.These cells could be injected in the eyes to treat diseases like macular degeneration, glaucoma and the blindness by diabetes, according to the investigator Astrid Limb.The damage of the retina, the part of the eye that sends messages to the brain is responsible for the majority of the cases of loss of the vision.
