Abstract

The 8D9 antigen, a cell surface protein isolated from chicken brain that is related to the L1 class of cell adhesion molecules, is shown to contain an activity that promotes the attachment of neurons and the outgrowth of neurites from chicken tecta and mouse cerebellum. When purified 8D9 antigen is attached to a nitrocellulose-coated substrate, neurons rapidly attach and extend unfasciculated neurites. Little or no attachment of astroglia, oligodendroglia, and fibroblast-like cells to the 8D9 antigen is observed. We propose that a function of the 8D9 antigen is that of a neurite extension-promoting substrate in axon fascicles and in regeneration of peripheral nerves.

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.
