Fig 4. Upregulation of COL1A1 in distal vasculature of miR-29 DKO lungs.

(A&B) Increased COL1A1 IHC signal is prominently associated with vessel walls, where endogenous miR-29 expression is highly expressed. (C&D) are enlarged images of highlighted areas of A&B by dashed line. All images are representative of four pairs of littermate-matched WT/DKO mice.
