"Revolutionizing Neuroscience: Mini-Brains Grown from Human Fetal Tissue"

Scientists have successfully grown cerebral organoids, or "minibrains," from human fetal brain tissue for the first time, opening up new possibilities for studying brain health and disease. These minibrains, which mimic aspects of full-size human brains, were grown to the size of a grain of rice and contained various cell types that self-organized into complex 3D structures. The researchers also triggered the growth of brain tumors within the minibrains and tested the tumors' response to existing cancer drugs. This breakthrough could provide fresh insights into brain development and diseases, and the authors aim to create more complex versions of the minibrains from fetal tissues at different stages of development.
