An Analysis of the Immunomodulatory Properties of Human Spheroids from Adipose-Derived Stem Cells
2023
Aims Current methods to induce tolerance following allotransplantation or in autoimmunity carry significant morbidity, and research is very active in investigating alternative methods which could minimize toxicity. Spheroids from adipose stem cells (SASCs) are increasingly gaining interest, they hold a great proliferative and differentiating potential. An immunomodulatory effect has not been investigated on SASCs yet. In this study, we analysed the immunomodulatory properties of SASCs and compared them to ADSCs. Main methods Adipose stem cells (SASCs and ADSCs) and peripheral blood mononuclear cells (PBMCs) were collected from healthy individuals. We analysed the cytokine production and pro…

Injectable xyloglucan hydrogels incorporating spheroids of adipose stem cells for bone and cartilage regeneration
2021
Abstract Cartilage or bone regeneration approaches based on the direct injection of mesenchymal stem cells (MSCs) at the lesion site encounter several challenges, related to uncontrolled cell spreading and differentiation, reduced cell viability and poor engrafting. This work presents a simple and versatile strategy based on the synergic combination of in-situ forming hydrogels and spheroids of adipose stem cells (SASCs) with great potential for minimally invasive regenerative interventions aimed to threat bone and cartilage defects. Aqueous dispersions of partially degalactosylated xyloglucan (dXG) are mixed with SASCs derived from liposuction and either a chondroinductive or an osteoinduc…
