USA - Scientists Grow Human Brain Cells in Rats

K. Farmer

Scientists have transplanted human brain cells into the brains of baby rats, where the cells grew and formed connections.

It’s part of an effort to better study human brain development and diseases affecting this most complex of organs, which makes us who we are but has long been shrouded in mystery.

The research builds upon the team’s previous work creating brain “organoids,” tiny structures resembling human organs that have also been made to represent others such as livers, kidneys, prostates, or key parts of them. 

Scientists transplanted those organoids into rat pups 2 to 3 days old, a stage when brain connections are still forming. The organoids grew so that they eventually occupied a third of the hemisphere of the rat’s brain where they were implanted. Neurons from the organoids formed working connections with circuits in the brain.

Researchers, whose study was funded partly by the National Institutes of Health, said they could do the same sorts of experiments using organoids made from the cells of people with disorders such as autism or schizophrenia—and potentially learn new things about how these conditions affect the brain, too.

Such experiments in animals raise ethical concerns. For example, Pasca said he and his team are cognizant of the rats’ well-being and whether they still behave normally with the organoids inside them, which he says they do. Still, Pasca does not believe this should be tried in primates. Ethicists also wonder about the possibility of brain organoids in the future attaining something like human consciousness, which experts say is extremely unlikely now.

Commentary

This experiment reminds one of the Scripture, “Now nothing will be restrained from them, which they have imagined to do” (Genesis 11:6b). The article further mentions a statement by Dr. Sergiu Pasca, senior author of the study, saying: “this is the first time these organoids have been placed into early rat brains, creating ‘the most advanced human brain circuitry ever built from human skin cells…” We notice that these scientists are only able to “create” brain-like structures from human skin cells that already exist. Thus, man is attempting to play God by using His already created materials. 

Another notable quote is: “Ethicists also wonder about the possibility of brain organoids in the future attaining something like human consciousness…” We know that the image of the beast in Revelation will “speak, and cause that as many as would not worship the image of the beast should be killed” (13:15b). Sounds like the Tribulation is nearly at our doorstep. (By K. Farmer)
