Research in Germany reveals the controversial cultivation of hundreds of “mini-brains” from stem cells, which in their development even form “functionally integrated bilateral optic vesicles ” (OVB).
These OVB organoids then progressively developed bilaterally symmetric optic vesicles, with their respective neuronal and non-neuronal cell types, according to the study published on Aug. 17.
These developing optic vesicles “including primitive corneal epithelial and lens-like cells, retinal pigment epithelia, retinal progenitor cells, axon-like projections, and electrically active neuronal networks,” the report explains.
These organoids were found to be sensitive to various light intensities, evidencing “the intrinsic ability to self-organize forebrain-associated primitive sensory structures in a topographically restricted manner,” it continues.
“And can allow interorgan interaction studies within a single organoid,” sending information to the brain, the study adds.
Also involved in this research is neuroscientist Jay Gopalakrishnan of Düsseldorf University Hospital.
“Eye development is a complex process, and understanding it could allow underpinning the molecular basis of early retinal diseases,” notes Sciencealert of the article.
“Thus, it is crucial to study optic vesicles that are the primordium of the eye whose proximal end is attached to the forebrain, essential for proper eye formation,” they add.
The experiments are conducted at the Institute of Human Genetics at the University Hospital, Düsseldorf, led by Dr. Elke Gabriel.
These scientific interventions raise ethical questions, some of which are raised by author Jazz Shaw.
“We may be delving into issues ranging from science to religion, stop and consider what’s being done,” Shaw wrote.
He adds, “We’re growing brains that begin from actual human brain cells. And after they grow for a while they produce brainwaves. Doesn’t that mean that they’re thinking?”
He further says, “If you don’t care for the idea of a soul, how about just consciousness?”
And he continues: “If so, there are very serious questions over what right we have to go tampering with these brains, to say nothing of destroying them when the experiment is finished.”
The issue of experimentation with human genetics is hotly debated. Experiments with human-animal hybrids and the creation of three-parent human embryos have already been questioned.
Even a leading Chinese scientist, He Jiankui, announced at the end of 2018 the creation of the first genetically modified babies.
Since then, the scientist has disappeared, a television program that celebrated his feat was depublished, and institutions that once supported him now disown him.
What the Chinese regime considered a great success was widely rejected by international scientists.
Scientists condemned He’s experiment as “illegal,” “unethical,” “unacceptable,” and “reckless.”
In addition to moral objections to manipulating what a human being is, the technology is ethically challenged because changes in an embryo could be inherited and eventually affect the entire gene pool.
Genetic modification of a human embryo also involves risks, such as introducing unwanted mutations or producing a baby whose body is composed of some modified and some unmodified cells.
