Materials and methods Adult mesenchymal stem cells derived from adipose tissue (ADSCs) were isolated, characterized, and seeded on the hydrogel. After 15 days of culture, the scaffolds were analyzed with scanning electron microscopy (SEM) and real-time PCR to assess osteogenesis, and by means array CGH (Comparative Genomic Hybridization) to test their safety. Conclusion The PEG hydrogel, loaded with adult mesenchymal stem cells, seems to have an osteogenic potential and therefore could be successfully used as a membrane in the treatment of bone defects.
