Transforming growth factor type beta: rapid induction of fibrosis and angiogenesis in vivo and stimulation of collagen formation in vitro.
Open accessAbstract
Transforming growth factor type beta (TGF-beta), when injected subcutaneously in newborn mice, causes formation of granulation tissue (induction of angiogenesis and activation of fibroblasts to produce collagen) at the site of injection. These effects occur within 2-3 days at dose levels than 1 microgram. Parallel in vitro studies show that TGF-beta causes marked increase of either proline or leucine incorporation into collagen in either an NRK rat fibroblast cell line or early passage human dermal fibroblasts. Epidermal growth factor (EGF) and platelet-derived growth factor (PDGF) do not cause these same in vivo and in vitro effects; in both rat and human fibroblast cultures, EGF antagonizes the effects of TGF-beta on collagen formation. We have obtained further data to support a role for TGF-beta as an intrinsic mediator of collagen formation: conditioned media obtained from activated human tonsillar T lymphocytes contain greatly elevated levels of TGF-beta compared to media obtained from unactivated lymphocytes. These activated media markedly stimulate proline incorporation into collagen in NRK cells; this effect is blocked by a specific antibody to TGF-beta. The data are all compatible with the hypothesis that TGF-beta is an important mediator of tissue repair.

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.
