Stem Cells Mimic Human Brain

This article highlights how researchers have discovered that by mixing stem cells originating from the skin, with nutrients and oxygen, the cells exhibit characteristics similar to that of the human brain. In the past, researchers have also been able to culture stem cells into growing structures similar to that of the human eye and also the cortex of the brain. Likewise, the stem cells in this most recent advancement form clumps of tissue that is reminiscent of the brain. Although they do not form a perfect and complete copy, the stem cells resemble natural connective tissues that can be found in the brain. In addition, it is worth noting that these clumps of tissue continued to grow to where they resembled a fetus’ brain in the ninth week of development. This recent discovery holds promise in opening doors to better understanding the brain and neurological diseases.  Researchers can now apply their studies of neurological disease and disorder to a better model of the human brain as opposed to other species, such as rats, because of neurological differences.

I found this article to be interesting because it seems as if researchers have done nearly the impossible. To be this incredibly close in replicating structures similar to that of the human brain with stem cells highlights the practicality of the cells and what human exploration can do.  With this latest advancement, it is in high hopes that we will be able to gain a better understanding of neurological disorders and help others with those disorders.
