Precursor cells of oligodendrocytes in rat primary cultures. 1985

A Espinosa de los Monteros, and G Roussel, and C Gensburger, and J L Nussbaum, and G Labourdetti

In monolayer primary cultures of brain from newborn rats, which contain astrocytes and oligodendrocytes, a new morphological cell type (flat black cells) was observed. Microphotographs of different areas of the monolayer, taken every 30 min, showed that these flat black cells can divide and that they undergo morphological transformation in vitro. They give rise to oligodendrocytes which were identified by their characteristics morphology but also by their content of W1 Wolfgram protein. These findings suggest that the flat black cells are precursors for oligodendrocytes, in culture.

D009185 Myelin Proteins MYELIN-specific proteins that play a structural or regulatory role in the genesis and maintenance of the lamellar MYELIN SHEATH structure. Myelin Protein,Protein, Myelin,Proteins, Myelin
D009457 Neuroglia The non-neuronal cells of the nervous system. They not only provide physical support, but also respond to injury, regulate the ionic and chemical composition of the extracellular milieu, participate in the BLOOD-BRAIN BARRIER and BLOOD-RETINAL BARRIER, form the myelin insulation of nervous pathways, guide neuronal migration during development, and exchange metabolites with neurons. Neuroglia have high-affinity transmitter uptake systems, voltage-dependent and transmitter-gated ion channels, and can release transmitters, but their role in signaling (as in many other functions) is unclear.

D009836 Oligodendroglia A class of large neuroglial (macroglial) cells in the central nervous system. Oligodendroglia may be called interfascicular, perivascular, or perineuronal (not the same as SATELLITE CELLS, PERINEURONAL of GANGLIA) according to their location. They form the insulating MYELIN SHEATH of axons in the central nervous system.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D001923 Brain Chemistry Changes in the amounts of various chemicals (neurotransmitters, receptors, enzymes, and other metabolites) specific to the area of the central nervous system contained within the head. These are monitored over time, during sensory stimulation, or under different disease states. Chemistry, Brain,Brain Chemistries,Chemistries, Brain
