Fig. 5From: Ultrastructural changes during osteogenic differentiation in mesenchymal stromal cells cultured in alginate hydrogelDifferences in ultrastructure between BMSC cultured in osteogenic medium (a, c) and in standard medium (b, d) revealed by FIB milling and SEM observations of critical point-dried cells, captured with InLens (a, b) and ESB (c, d) detectors. Asterisks indicate areas composed of heavier elements, V vesicular structure; scale bars 400 nmBack to article page
