Figure 2

Non-muscle myosin II (NM II) isoforms are expressed at both airway tips and stalks in developing fetal mouse lung. Confocal images of E15 tip (A–C), E15 stalk (D–F), E18 tip (G–I), and E18 stalk (J–L) regions of fetal mouse lungs were immunostained using antibodies against E-cadherin (green) and either NM II-A, NM II-B, or NM II-C (red). (A, D, G, J) NM II-A is expressed in fetal mouse lung mesenchyme and epithelium in the tip and stalk regions. (B, E, H, K) NM II-B is expressed primarily in the mesenchyme in both the tip and stalk regions at E15 and E18. (C, F, I, L) NM II-C co-localizes with E-cadherin in epithelial cells at the tip and stalk regions at E15 and E18. Scale bar, 10 µm.
