The Stem Cell Report with Janet Rossant
Stem cell science has catapulted to the forefront of biomedical research over the last decade, bringing with it the potential to transform human health and the treatment of devastating diseases and disorders. Janet Rossant, an internationally recognized stem cell pioneer and the dynamic editor-in-chief of Stem Cell Reports, explores basic discoveries in stem cell research and its application. Dr. Rossant goes “beyond the paper,” bringing authors together to draw new insights and explore the questions and creativity that drive new breakthroughs. Stem Cell Reports, published by the International Society for Stem Cell Research (ISSCR), is an open-access, peer reviewed journal that supports the field of stem cell research and regenerative medicine.

No Oligo Monopoly: Oligodendrocyte Precursor Cells in the Developing Cortex
Myelination is one of the last events during mammalian brain development and is thought to continue into young adulthood in humans. Even in adulthood, ongoing low-level myelination is essential for neural homeostasis, and for dynamic processes such as learning and memory. Deficits in myelination resulting in abnormal white matter and disruption of neuronal function are observed in a wide variety of disorders of the CNS. One strategy for alleviating these deficits is to enhance the genesis of myelin-forming oligodendrocytes from their upstream precursor parents, oligodendrocyte precursor cells (OPCs). However, the capability of these OPCs to contribute to remyelination in injury or disease in the adult CNS remains unclear. To better understand adult oligodendrogenesis and remyelination, our guests today characterized and compared murine OPCs during early postnatal myelination with those from adult injury-induced adult remyelination. Their findings identify two developing OPC groups subserving distinct postnatal functions and suggest that neonatal and adult OPC-mediated oligodendrogenesis are fundamentally different, The findings have important implications for therapeutic interventions aimed at myelin repair.
