Studying Color Vision in a Dish
Studying Color Vision in a DishPosted on December 13th, 2018 by Dr. Francis CollinsCredit: Eldred et al., ScienceResearchers can now grow miniature versions of the human retina—the light-sensitive tissue at the back of the eye—right in a lab dish. While most “retina-in-a-dish” research is focused on finding cures for potentially blinding diseases, these organoids are also providing new insights into color vision. Our ability to view the world in all of its rich and varied colors starts with the retina’s light-absorbing cone cells. The cells that are labeled with red show the highly sensitive rod cells, which aren’t involved in color vision, but are very important for detecting motion and seeing at night. However, mice and many other animals don’t view colors like we do, which has made it very difficult to answer some important questions about human color vision.
