以往研究证明局部应用PDGF(血小板衍生生长因子)或bFGF(碱性成纤维细胞生长因子)可促进遗传性糖尿病小鼠背部创面愈合,但对正常小鼠则无加速创面愈合的作用。实验旨在观察局部应用PDGF或bFGF是否能够促进营养不良的糖尿病或无糖尿病小鼠的组织修
Previous studies have shown that topical application of PDGF (platelet-derived growth factor) or bFGF (basic fibroblast growth factor) can promote healing of hereditary diabetic mice with a wound on the back, but does not accelerate wound healing in normal mice. The experiment was designed to investigate whether topical application of PDGF or bFGF can promote tissue malnutrition in diabetic or non-diabetic mice
