After decades of relative neglect, star-shaped brain cells called astrocytes are finally getting their due. To gather insight into a critical aspect of brain development, a team of scientists examined the maturation of astrocytes in 3-D structures grown in culture dishes to resemble human brain tissue. The study, which confirms that the lab-grown cells develop at the same rate as those found in human brains, was published in Neuron, August 16, 2017.
