| Summary: | Advancements in regenerative medicine increasingly focus on developing scaffolds that not only support stem cell proliferation but also guide their differentiation into specific cell types essential for tissue repair. Adipose-derived stem cells (ASCs) are considered a promising option for bone regeneration therapies, primarily because they are readily accessible and can be obtained in large quantities with minimally invasive procedures. This study aims to establish a straightforward and effective novel experimental model for incorporating ASCs into silicon calcium phosphate cement (Si-CPC), potentially enhancing the scaffold’s osteoconductive properties and facilitating bone tissue regeneration. The in vivo evaluation of the cement was carried out using a rabbit model, where titanium cylinders were implanted into pre-drilled slits in the parietal cortical bone. One cylinder served as a control and was filled with Si-CPC alone, while the other received Si-CPC combined with adipose-derived stem cells applied across the surface of the granules. Four weeks after the intervention, histology and histomorphometry tests are performed. In the histology test, the Si-CPC with ASCs presented the training of bony bridges between the material granules. We will need a larger sample to evaluate the amount of new bone formed. However, we can conclude that this new method of incorporating stem cells into bone cements could be a promising tool in bone engineering. |
