Im Labor gezüchtete Netzhäute enthüllen das Geheimnis hinter der Entwicklung des hochauflösenden menschlichen Sehvermögens

Researchers at Johns Hopkins University have discovered a new cellular mechanism behind how humans develop sharp, high-acuity vision.

Using lab-grown retinal organoids, the team identified how the eye populates the foveola with the specific light-sensing cells needed for clear vision. Foveola is the tiny central region responsible for sharp, high-definition vision.

It was discovered that sharp human vision is formed during fetal development through a dynamic interplay between a vitamin A derivative (retinoic acid) and thyroid hormones.
