Lens,heal thyself:a significant advance in regenerative ophthalmology

摘要

A few animals,notably Cnidarians,including Hydra and some species of jellyfish,and Planaria possess unlimited regenerative capacity and effectively elude both senescence and biological aging(1).However,humans,and most other vertebrates,exhibit limited regenerative capability for a few tissues that declines with age.Given the isolation of human embryonic stem cells(ESCs),the creation
