Abstract:
The neuron‐like differentiation of bone marrow‐derived mesenchymal stem cells (BMMSCs) has been extensively studied. However, the alternations of the cell‐surface ultrastructures and the membrane tension/reservoir of the cells during this differentiation process are poorly understood. Therefore, atomic force microscopy (AFM) was utilized in this study to observe the cell‐surface ultrastructural changes among rat bone marrow‐derived mesenchymal stem cells (rBMMSCs), partially differentiated cells, and fully differentiated neuron‐like cells. By analyzing the stiffness of plasma membranes, lamellipodial extensions, average heights of small membrane protrusions and relatively larger uplifted structures, and peak‐peak spacing among protrusions and/or uplifted structures, we found that the membrane reservoir may potentially decrease upon the differentiation from rBMMSCs to partially differentiated cells and to fully differentiated neuron‐like cells. The results may help to better understanding the membrane tension of various types of cells and related biological processes, such as membrane traffic, cell adhesion, motility, differentiation, among others. The data also implies that AFM may be a useful tool for evaluating membrane reservoir by imaging cell‐surface ultrastructures. SCANNING 33: 69–77, 2011. © 2011 Wiley Periodicals, Inc.
