Lab-grown retinas explain why people see colors dogs can't

Cultivated human retinas in a laboratory setting provided a groundbreaking revelation regarding the pivotal role of retinoic acid in the genesis of color-sensing cells, countering the prevailing notion that thyroid hormones dictated this process.
The elucidation of retinoic acid's influence deepens our comprehension of various color vision disorders and age-related ocular ailments, offering promising avenues for diagnostic and therapeutic advancements.
It has been uncovered that retinoic acid exerts a profound regulatory effect, determining whether cones within the retina specialize in perceiving red or green wavelengths, thus shaping the intricate spectrum of human color perception.
Contrary to long-held assumptions suggesting the stochastic formation of red cones, the discovery underscores a meticulously orchestrated sequence of events orchestrated by retinoic acid, challenging conventional understanding in the field.
The newfound insights hold transformative potential, potentially paving the way for innovative treatments targeting vision impairments such as macular degeneration, thereby offering hope for individuals grappling with these debilitating conditions.
