Immunohistochemistry of CD90/Thy-1 in murine precision cut lung slices.

<p>A) The anti-CD90/Thy-1 antibody (green) stains a vascular system (arrowheads) in murine precision cut lung slices that is distributed throughout the lung. Red staining shows immunoreactivity for α-smooth muscle actin. AW: airways. B) Initial CD90/Thy-1-immunoreactive capillaries (arrowheads) in the alveolar region. C) The CD90/Thy-1-immunoreactive vascular network is interconnected. D) A CD90/Thy-1-immunoreactive valve (arrowheads). E) Only close to the hilum, α-smooth muscle actin-immunoreactive cells (red, arrow) were found on CD90/Thy-1-immuoreactive vessels.
