| Research Abstract |
Mesenchymal stem cells from rat adult bone marrow(r-MSCs) were cultured on Honeycomb films and FI-PEARL films without cytkines for cell growth. The anomalous cellular adhesion and division were found in such a way that r-MSCs did not spread at all keeping semispherical original shape along culture and divided directly in the semispherical cell bodies. The proliferative ability on PE-PEARL films was higher than that on a commercially available polystyrene culture plate. These films enabled easy recovery of MSCs by rinsing with water without the conventional trypsin treatment. The present study suggested that both films are promising scaffolds for mesenchymal stem cells which make the bio risk free subculture of MSCs possible. We obtained technical data useful for constructing a sophisticated technique based on tip-enhanced Rama scattering for characterizing the surface and inside of a living mesenchymal stem cell.
