Cellule mesenchimali da tessuto adiposo (ASC) 1. Nel tessuto adiposo la concentrazione di ASC è circa 500 volte superiore a quello delle BMSC nel midollo osseo 2. Le ASC hanno un potenziale di espansione di circa 7 volte superiore alle BMSC. 3. Le ASC hanno le stesse potenzialità differenziative, anti-fibrotiche, anti-apoptotiche e anti- infiammatorie delle BMSC. 44 ADIPOA ASC isolation Fragmentation Adipose tissue Pellet seeding ASC Enzymatic treatment Centrifugation Fenotipo e potenzialità differenziative delle ASC Miocytes Analisi in citometria a flusso di ASC evidenzia che sono positive CD105 105,, CD CD73 73,, CD CD29 29,, CD CD44 44,, a CD CD CD90 90 e negative a CD CD106 106,, CD CD45 45,, CD CD14 14,, CD CD34 34,, and CD CD31 31 Adipocytes Osteocytes Chondroytes Adipose derived stromal cells for osteoarthritis treatment (ADIPOA) Collaborative Project Health-2009-1.4-3 Activation of endogenous cells as an approach to regenerative medicine 2 Months follow-up: Safranin-O staining CONTROL 100 µm 500 µmc 2x106 ASC 100 µm 500 µmc 6x106 ASC 100 µm 500 µm Acknowledgements Laboratory of Immunology and Genetics Dr.ssa Brunella Grigolo Dr.ssa Gina Lisignoli Dr. ssa Giovanna Desando Dr.ssa Carola Cavallo Laboratory of Experimental Surgery Prof. Roberto Giardino Dr.ssa Milena Fini Dr. Gianluca Giavaresi Dr.ssa Matilde Tschon Orthopaedic Divisions Prof. Sandro Giannini Dr. Roberto Buda Prof. Maurilio Marcacci Dr.E.Kon Grants from: Grazie per l’attenzione Istituto Ortopedico Rizzoli (Biblioteca))
