Growth factor mRNA and protein in preserved human amniotic membrane
Abstract
PURPOSE: To investigate the expression of growth factor mRNA and the level of growth factor protein in preserved human amniotic membrane (AM). METHODS: RT-PCR was used to examine the expression of mRNA for eight growth factors (EGF, TGF-alpha, KGF, HGF, bFGF, TGF-beta1, -beta2, -beta3) and two growth factor receptors (KGFR and HGFR) in human AM preserved at -80 degrees C for one month. In addition, ELISAs were used to measure the protein concentrations of seven growth factors (EGF, TGF-alpha, KGF, HGF, bFGF, TGF-beta1, -beta2) in preserved human corneas and in AM both with and without amniotic epithelium. RESULTS: RT-PCR revealed that human AM expresses mRNA for EGF, TGF-alpha, KGF, HGF, bFGF, TGF-beta1, -beta2, -beta3, KGFR and HGFR, while ELISAs showed that it contains EGF, TGF-alpha, KGF, HGF, bFGF, TGF-beta1, -beta2. AM without amniotic epithelium also contains all seven growth factors examined, however, in this tissue the protein levels of EGF, KGF, HGF and bFGF were found to be significantly lower than in native AM. CONCLUSIONS: Preserved human AM expresses mRNAs for a number of growth factors and contains several growth factor proteins that might benefit epithelialization after AM transplantation. High levels of EGF, KGF, HGF and bFGF in AM with amniotic epithelium as compared to AM without amniotic epithelium suggest an epithelial origin for these growth factors. We feel that EGF, KGF and HGF in particular might play important roles in ocular surface wound healing after AM transplantation.

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.
