根据近年来对胎儿脐血有关基础研究和临床应用研究的资料发现，脐血中的某些细胞成分及生化成分对骨折的愈合可能产生刺激作用和促进作用．经采用实验动物模型骨折端注射脐血的方法，经过生化检验、Ｘ线拍片、肉眼观察、组织切片、透射电镜超微结构观察等，结果显示，胎儿脐血对促进骨折愈合具有明显作用，愈合时间较对照组平均缩短一周以上。
According to the research on fetal umbilical cord blood in recent years based on the basic research and clinical application of the data found that some of the cellular components of umbilical cord blood and biochemical components of the fracture healing may have a stimulating effect and promotion. The method of injecting umbilical cord blood by using animal models of experimental fracture was biochemical test, X-ray film, macroscopic observation, histological section and transmission electron microscopy. The results showed that fetal umbilical cord blood had a significant effect on promoting fracture healing and healing The average time shorter than the control group more than a week.
