CG‐4, A new bipotential glial cell line from rat brain, is capable of differentiating in vitro into either mature oligodendrocytes or type‐2 astrocytes
Abstract
We have established a permanent cell line (CG‐4) of rat central nervous system glial precursors from primary cultures of bipotential oligodendrocyte‐type 2‐astrocyte (O‐2A) progenitor cells, which were kept proliferating with the mitogen(s) secreted by the neuronal B104 cell line. The CG‐4 cells have a normal karyotype and display the properties of normal O‐2A cells. CG‐4 cells can be propagated in serum‐free culture medium supplemented with medium conditioned by B104 cells for unrestricted periods of time as O‐2A cells, characterized by the presence of the A2B5 surface marker and the absence of markers specific for Oligodendrocytes (galactocerebroside, myelin basic protein) or type 2‐astrocytes (glial acidic fibrillary protein). bFGF and PDGF are potent mitogens for CG‐4 cells and their combination can substitute for the B104‐derived mitogen(s). CG‐4 cells are capable of differentiating into either Oligodendrocytes or type 2‐astrocytes. Differentiation into Oligodendrocytes occurs after withdrawal of the mitogen. Replacement of the mitogen with fetal calf serum (20%), in contrast, induces 50% of the CG‐4 cells to differentiate into type 2‐astrocytes. Pure cultures of Oligodendrocytes or type 2‐astrocytes can be generated in substantial amounts from CG‐4 cells and maintained for several weeks in medium containing 5% fetal calf serum.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
