Bone Marrow Stem Cell and Decellularized Human Amniotic Membrane for the Treatment of Nonhealing Wound After Radiation Therapy.

Objectives: In this study, our aim was to create a bioactive wound dressing that combined decellularized and lyophilized human amniotic membrane and freeze-dried rat bone marrow stem cells for the treatment of nonhealing wounds.

Materials And Methods: For the decellularized human amniotic membrane, sodium dodecyl sulfate and 1% Triton X-100 were used. The mononuclear fraction of bone marrow stem cells was isolated by density gradient centrifugation using Ficoll Paque Plus (GE Healthcare Bio-Sciences, Pittsburgh, PA, USA).

BONE GRAFTS FOR RECONSTRUCTION OF BONE DEFECTS (REVIEW).

Reconstruction of large size defects of bone is a challenging task. To this date, discussions and controversies on selection of auto-, allo-, xeno- or synthetic grafts continue to take place. Vascularized autologous bone graft is considered as gold standard in reconstruction of large size defects of bone; however an additional surgery is required for obtaining it.
