Effects of Transforming Growth Factor β1, on Scar Production in the Injured Central Nervous System of the Rat
Abstract
In the central nervous system (CNS), nerve regeneration after traumatic injury fails. The formation of a dense fibrous scar is thought to restrict in part the growth of axonal projections, providing one of the many reasons that complete lesions of neural pathways in the adult mammalian CNS are rarely followed by significant functional recovery. In order to determine which mechanisms mediate scar formation in the CNS and to investigate whether they can be modulated in vivo, we have attempted to define the potential role of trophic factors. Our previous studies have shown the focal elevation of transforming growth factor β 1 (TGFβ 1) expression in lesioned CNS tissue. In the studies described here, we demonstrate that TGFβ 1 participates in the scarring response in the rat brain. First, the elevated protein levels of TGFβ 1 are localized to specific populations of injury‐responsive cells in the traumatized CNS. Furthermore, the injection of TGFβ 1 into the brains of injured rats causes a dramatic increase in the scarring response. Conversely, when neutralizing TGFβ 1 antibodies are administered, the deposition of fibrous scar tissue and the formation of a limiting glial membrane that borders the lesion is significantly attenuated, thus establishing a role for the endogenous growth factor in regulation of the non‐glial component of the scar. In implicating TGFβ 1 in the scarring response in the CNS, the potential use for TGFβ 1 antagonists as inhibitors of scar formation in the injured mammalian CNS is self‐evident.

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.
