Stem Cell Technology One Day Will Be Able to Restore Sight

According to a new research, a stem cell technology one day may restore sight to the blind people.restore sight

In this study, a group of scientists from the RIKEN Center for Developmental Biology, Japan, led by the researchers Masayo Takahashi and Michiko Mandai, wanted to test whether the animals' vision can be restored. They placed mice in cages consisting of two rooms. The floor of one of the rooms was electrified at random points in time. Preceding each electric shock, the team flashed a warning light. To avoid the shock, the mouse had to see the light flash and move to the adjoining room.

The procedure managed to restore sight in nearly half of the mice with end-stage retinal degeneration. This success was due to the researchers' choice of cells.

Masayo Takahashi explains: "It is still a developing stage therapy, and one cannot expect to restore practical vision at the moment. We will start from the stage of seeing a light or large figure, but hope to restore more substantial vision in the future."
