New ocular device helps administer antioxidants in the eye

Due to their sun and oxygen exposure, the eyes are especially susceptible to oxidative stress, which causes several ocular pathologies. One of the antioxidants that is most present in the eyes to fight oxidative stress is glutathione, the defecit of which is linked to several ophthalmologic diseases. The research group of the CEU UCH of Valencia headed by professor Alicia […]

Study differentiates iPS cells into various ocular lineages

The discovery of pluripotent stem cells, which have the ability to differentiate into the huge range of different cell lineages that make up the human body, signaled the start of a new era in biological science and medicine. Although we are also now able to reprogram regular cells to exhibit this pluripotency, we still have much to learn about the […]
