Introduction
In adipose tissue-derived osteogenic cells (ADOC), osteoblast markers and surface proteins were determined and compared with osteoblasts harvested from cancellous bone (OB).
Method
Osteocalcin (OC), core binding factor 1 (CBFA1), collagen type 1 (Coll1), alkaline phosphatase (ALP), nucleostemin (NS), and surface proteins CD 10, CD44, CD 59 and CD 105 were analyzed using RT-PCR, immunofluorescence and Western blot.
Results
Osteocalcin expression was more distinct in OB than in ADOC, but the other markers and surface proteins showed no differences.
Conclusion
These data support the use of adipose tissue for future regenerative medicine; however, further studies are necessary to establish the role of long-term differentiation.
