Label-Free Imaging of Umbilical Cord Tissue Morphology and Explant-Derived Cells

Figure 7

Staining of WJ-MSCs in culture for (a) αSMA, (b) ALDH1A1, and (c) Oct4 expression. (d) Representative control staining without primary antibody. All cells stain positive (brown) for ALDH1A1, but not for αSMA and Oct4 (black arrows), indicating that a heterogeneous cell isolate was obtained. Scale bars = 50 μm. Representative images of at least 3 donors are shown.
