Abstract (original English)
Adipocytes and osteoblasts derive from a common mesenchymal progenitor present in a range of connective tissues. Differentiation of the progenitors toward the two cell lineages can be induced in vitro through well-established protocols, and leads to the appearance of lipid-laden adipocytes and osteoblasts embedded in a mineralized matrix. The formation of these two lineages in cell cultures can be monitored using lipophilic dyes such as Oil Red O and substances binding to mineral deposits such as Alizarin Red S, respectively. However, these common staining techniques require cell fixation and are thus incompatible with live analyses. Recently, alternative approaches using vital stains have allowed the dual visualization and fluorescence imaging of adipogenic and osteogenic lineages in live cultures. Here we present the concomitant analysis of cultures containing adipogenic and osteogenic cell types using live staining, combining LipidTox Red and tetracycline with NucRed nuclear counterstain for confocal imaging. This approach can be applied to visualize the kinetics and 3D structure of differentiating mesenchymal cultures over time and highlights the interaction of adipose and mineralized compartments associated with bone marrow stroma.
