Transplantation Of Autologous Bone Marrow Mesenchymal Stem Cells With Platelet-Rich Plasma Accelerate Distraction Osteogenesis In A Canine Model
Journal Title: Cell Journal(Yakhteh) - Year 2015, Vol 17, Issue 2
Abstract
Objective: Distraction osteogenesis (DO) is a surgical procedure used to generate large volumes of new bone for limb lengthening. Materials and Methods: In this animal experimental study, a 30% lengthening of the left tibia (mean distraction distance: 60.8 mm) was performed in ten adult male dogs by callus distraction after osteotomy and application of an Ilizarov fixator. Distraction was started on postoperative day seven with a distraction rate of 0.5 mm twice per day and carried out at a rate of 1.5 mm per day until the end of the study. Autologous bone marrow mesenchymal stem cells (BM-MSCs) and platelet-rich plasma (PRP) as the treatment group (n=5) or PRP alone (control group, n=5) were injected into the distracted callus at the middle and end of the distraction period. At the end of the consolidation period, the dogs were sacrificed after which computerized tomography (CT) and histomorphometric evaluations were performed. Results: Radiographic evaluationsrevealed that the amount and quality of callus formations were significantly higher in the treatment group (P<0.05). As measured by CT scan, the healing parametersin dogs of the treatment group were significantly greater (P<0.05). New bone formation in the treatment group was significantly higher (P<0.05). Conclusion: The present study showed that the transplantation of BM-MSCs positively affects early bony consolidation in DO. The use of MSCs might allow a shortened period of consolidation and therefore permit earlier device removal.

Altered Expression of High Molecular Weight Heat Shock Proteins after OCT4B1 Suppression in Human Tumor Cell Lines
Objective OCT4B1, a novel variant of OCT4, is expressed in cancer cell lines and tis- sues. Based on our previous reports, OCT4B1 appears to have a crucial role in regulating apoptosis as well as stress response [heat sh...
Taraxerol Induces Cell Apoptosis through A Mitochondria-Mediated Pathway in HeLa Cells
Objective: Taraxerol acetate has potent anti-cancer effects via the induction of apoptosis, autophagy, cell cycle arrest, and inhibition of cell migration. However, whether taraxerol induced apoptosis and its underlying...
