Figure 2: Visualization of FoxP3+ GFP+ Treg cells in a DSS-induced colitis model.
From: In vivo wide-area cellular imaging by side-view endomicroscopy
(a) Map of GFP-expressing Treg cells taken before DSS treatment (day −1). (b) Magnification of the boxed area in a, showing Treg cells (green) and blood vasculature (red). Inset, close-up of the boxed region. (c) A typical image of Treg cells at day 7 in the recovery phase of colitis. Blood vessels in b were visualized by intravenously injected Evans Blue. Scale bars, 200 μm (20 μm in the inset).
