Figure 4.

Anti-collagen type I staining in the lacrimal gland of GFP⁺ transplanted mice. Formalin-fixed frozen sections of recipient mice lacrimal glands were stained with an anti-collagen type I antibody. Representative figures from independent experiments (allogeneic n = 9, syngeneic C57BL/6 n = 9, B10.D2 n = 3). The allogeneic recipient (top), as well as both syngeneic models (middle and bottom), were collagen type I positive for most (>85%) of the GFP⁺ cells. DAPI (blue), GFP (green), collagen type I (red), and double-positive cells (yellow).Scale bar = 50 µm, 400× magnification.
