Repair of critical size rat calvarial defects using endometrial-derived stem cells embedded within gelatin/apatite nanocomposite scaffold

Human stromal stem cells derived from endometrium (hESCs) are a type of multipotent stromal cells of the proven ability to differentiate into osteogenic lineage. Thus, it was suggested that these cells may be used to repair skeletal defects. In this study, Human ESCs were extracted from female endometrium and harvested. Biomimetic gelatin/apatite (Gel/Ap) scaffolds with and without harvested cells were implanted in a Critical size calvarial defects in the cranial bone of adult male rat. To CT-Scan and Histological studies were performed to investigate the level of bone formation after 8 weeks of surgery. Results confirmed that the treated defects with the bare and hESCs grafted Gel/Ap scaffold showed significant bone formation and maturation in comparison with the control group.
