Abstract

The purpose of this study was to test the hypotheses that development of mature vimentin+/α-smooth muscle actin+/desmin+ (V+A+D+) myofibroblasts from corneal fibroblasts is regulated by transforming growth factor (TGF) β and platelet-derived growth factor (PDGF); and that myofibroblast development in vitro follows a similar developmental pathway as it does in vivo. Mouse corneal stromal fibroblasts (MSF) were isolated from the corneas of Swiss Webster mice and cultured in serum-free media augmented with DMEM/F12 and varying doses of TGFβ (0.1-2.0 ng/ml), with and without mouse PDGF-AA and/or PDGF-BB (2.0 ng/ml), to study the transition of the MSF to V+A+D+ myofibroblasts. The mean percentage of vimentin+, α-SMA+ and desmin+ cells was determined at each time point (2-15 days), with each growth factor concentration. MSF in vitro were noted to undergo the same developmental transition from V+A-D- to V+A+D- to V+A+D+ myofibroblasts as precursors undergo in vivo. TGFβ at a dose of 0.5 ng/ml and 1.0 ng/ml with 2.0 ng/ml PDGF-AA and 2.0 ng/ml PDGF-BB in DMEM/F12 serum-free media was optimal for the development of V+A+D+ myofibroblasts. This study defines optimal in vitro conditions to monitor the development of MSF into myofibroblasts. The combined effects of TGFβ and PDGF promote the full development of V+A+D+ myofibroblasts from MSF.

  • Co-stimulation of mouse corneal stromal fibroblasts with TGFβ and PDGF greatly enhances myofibroblast formation compared to TGFβ alone.

    “TGFβ and PDGF can work in concert, for example, in mouse corneal stromal fibroblasts co-stimulation of fibroblasts with TGFβ and PDGF greatly enhances myofibroblast formation compared to TGFβ alone (61).”

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.
