Abstract:
Aim: The study goals were to engineer and harvest scaffold-free undifferentiated/differentiated multilayer human adipose-derived stem cell (hADSC) cell sheets, in absence of treatment. Materials & methods: The hADSC are seeded in 35 mm culture dishes. At confluence or when multilayer cell sheets are formed, hADSC are treated with predefined differentiation culture media (adipocyte, chondrocyte and osteoblast). Results: Undifferentiated hADSC and differentiated adipocyte, osteoblast and chondrocyte hADSC multilayer cell sheets (hADSCmCS) have been harvested. Hematoxylin & eosin showed the formation of multilayer cell sheets. Undifferentiated hADSC multilayer cell sheets preserve their stem cell markers. Differentiated adipocyte, osteoblast and chondrocyte hADSCmCS expressed specific markers. Conclusion: This simple protocol opens possibilities to engineer scaffold-free hADSCm cell sheet to transplant them on damaged organs.
