Lab-grown retinas uncover secret behind high-definition human eyesight development
SMRTR summary
Johns Hopkins researchers used lab-grown retinal organoids to discover how humans develop sharp vision during fetal development. They found that between weeks 10-14, a vitamin A derivative first limits blue cone cell production in the foveola, then thyroid hormones convert remaining blue cones into red and green cones needed for high-definition sight. This breakthrough challenges previous theories and could lead to treatments for macular degeneration through engineered cell transplants.
