Enhancement of bone formation , at the end of lengthening phase ,is one of most important part of studies in this field.
A common project by veterinary college of Tehran university, Rooyan institute and our team , started on 2005 .
This animal study was planned to assess positive effect of stem cells to accelerate bone formation at lengthening site. Fortunately this study , showed that stem cells can increase bone formation by 45%
This study output got medical morals council acceptance for human use.
By now , we have used stem cells many times for delayed union cases with considerable results.
Our study is published in yakhteh journal .
Following pictures show our study steps
۱-bone marrow aspiration
** Bone related stem cells collected from smear by centrifuge.
** Culture of collected cells to increase their numbers.
** Meanwhile operated animals passing lengthening period .
** Then stem cell and PRP injection in lengthening site at mid phase and end phase of 6 cm lengthening.
** Control group only were injected PRP and placebo.
** Results ,proved 45% increase of bone formation in stem cell group.
