How to Make a Brain: New Experiments Challenge Existing Picture

For decades, the scientific community has largely agreed that the brain develops from a single type of starter cell. However, recent experiments challenge this long-held belief, suggesting that two different types of progenitor cells are actually required to form the complex organ. These findings could have significant implications for our understanding of brain development and disorders. One key area of interest is the use of brain organoids, miniature models of the brain created in the laboratory, which can help researchers better understand the mechanisms underlying various diseases and potentially lead to new treatments.
