respiratory system
• doxycycline treated embryos exhibit an extended domain of blood vessels into the expanded lung mesenchyme at E13.5
|
• beginning at E12.5, doxycycline treated embryos exhibit enlarged lung size
|
• doxycycline treated embryos exhibit increased luminal space, fewer epithelial airways and a wide band of mesenchyme separating epithelial ducts at E14.5
|
• doxycycline treated embryos exhibit a reduction in epithelial branching at E11.5 and E12.5
• beginning at E12.5, doxycycline treated embryos exhibit an arrest in branching and luminal dilation
|
• doxycycline treated embryos exhibit a large mesenchymal expansion in the lungs at E11.5 and E12.5
|
• doxycycline treated embryos show an absence of smooth muscle in the sub-epithelial compartment of lungs at E14.5, although it is present surrounding large blood vessels
