Assessment of the MSC/β-TCP composite. (Aa,b,c) Immediately after bone marrow circulated in the SECCS, spindle cells were found on the porous β-TCP scaffold. (Ba,b,c) After 10-day in vitro culture, many spindle cells were found on the surface and internal space of β-TCP. (C) After 10-day in vitro culture, ALP staining of MSC/β-TCP composites showed red colonies, indicating ALP activity.
