Objective:
To observe the expression characteristics of EGFR and FGFR-2 in normal skin from fetal and adult, and attempted to probe the molecule mechanism of fetal scarless healing.
Methods:
The skin samples of fetal and adult were taken from abortive fetus of obstetrics unit and donor site of plastic operation patients in our burn unit, respectively. EGFR and FGFR-2 were used as the biochemical markers for reparative cells. Immunohistochemistry staining technique was employed to determine the expressive levels of different epithelial cells markers.
Results:
There were EGFR and FGFR-2 antibody positive cells in normal skin from fetal and adult, but the expressive levels of EGFR and FGFR-2 protein had apparent difference, with the time of fetation increasing, the EGFR and FGFR-2 positive expression rate became stronger gradually. The number of FGFR-2 antibody positive cells found in adult skin was much more than that in fetal skin.
Conclusion:
There were the inherent differences of EGFR and FGFR-2 antibody immunohistochemistry staining in cells of adult and fetal skin. which may be an essential facet of fetal scarless healing.
