RT Journal Article SR Electronic T1 MicroRNAs Are Essential for the Developmental Switch from Neurogenesis to Gliogenesis in the Developing Spinal Cord JF The Journal of Neuroscience JO J. Neurosci. FD Society for Neuroscience SP 8245 OP 8250 DO 10.1523/JNEUROSCI.1169-10.2010 VO 30 IS 24 A1 Kang Zheng A1 Hong Li A1 Ying Zhu A1 Qiang Zhu A1 Mengsheng Qiu YR 2010 UL http://www.jneurosci.org/content/30/24/8245.abstract AB In the developing CNS, neurons and glia are sequentially produced from the ventricular neural progenitor cells. One fundamental question in developmental neurobiology is what signals or factors control the developmental switch from neurogenesis to gliogenesis. Here we report that microRNAs (miRNAs) play an essential role in this important developmental process. Inhibition of miRNA formation in Olig1Cre-mediated Dicer conditional knock-out mice disrupted both oligodendrogenesis and astrogliogenesis in the ventral neuroepithelial cells. By contrast, the early patterning and development of motor neurons were not affected in the mutant spinal cord tissue.
