"Stem Cell-Grown 'Mini Brains' Unexpectedly Develop Eyes"

Scientists have successfully grown "mini brains" from stem cells in a lab, which spontaneously developed rudimentary eye structures resembling those found in human embryos. These brain organoids, grown from induced pluripotent stem cells, provide insights into the process of eye differentiation and development, as well as eye diseases. The structures contained different retinal cell types, responded to light, and displayed retinal connectivity to brain tissue. This breakthrough could help study brain-eye interactions, model retinal disorders, and generate patient-specific retinal cells for personalized therapies.

Bacterial genes may have played a role in the development of vertebrate eyes.

Researchers at the University of California, San Diego, have found possible evidence of interdomain horizontal gene transfer leading to the development of the eye in vertebrates. The team used the IQ-TREE software program to trace the evolutionary history of genes associated with vision and found a promising candidate, a gene called IRBP, which is found in microbes and is an essential component of vision in all vertebrates. The researchers suggest that the IRBP gene may have been transferred from a microbe over 500 million years ago to an ancient vertebrate, leading to the development of light sensitivity and over time, to organs such as eyeballs.
