Immunohistochemical localization of MGL2+ DDCs, LCs and LN conduits.
(B) Distribution of MGL2 (red), PNAd (HEV), Langerin (LC) or ER-TR7 antigen (FRN) (blue in each panel) in the sensitization process. Areas indicated by the squares are magnified in the lower panels. FITC is shown in green. CR associated with HEV in a naive LN is adjacent to MGL2+ DDC only at its follicular side but not at the cortical side. Arrowheads indicate association of MGL2+ DDCs with ER-TR7+ FRN around HEV-associated CR. Scale bar, 100 μm.

Rat anti Mouse ER-TR7 antibody, clone ER-TR7 (MCA2402) used to demonstrate ER-TR7 expressing cells in murine digits by immunofluorescence on formalin fixed, paraffin embedded sections.
Image caption:
ER‐TR7 outlines tissue compartments of the digit. (A) H&E section of PN11 mouse digit tip shows compartments including nail bed (nb), ventral epithelium (ve), eccrine glands (eg), and a P3 rudiment composed of both cortical bone (b) and a proximal cartilaginous (c) growth plate. P3 encloses bone marrow (bm) and ends at the P3−P2 synovial joint (jt). P3 is connected to the proximal musculature through a tendon (tn) and is surrounded by loose dorsal and ventral CT (dct and vct). (B) Adjacent section from (A) stained against ER‐TR7. (C) Representative area captured at 400× from the dct in (B) (white asterisk). The boundary landmarks of the CT (labeled nb and b) are outlined with white dotted lines. ER‐TR7+ FRCs are marked (white + signs on nuclei) and these were discriminated (C, inset) at 1000× magnification by ER‐TR7 expression in membrane extensions (white arrows) or cytosol (white asterisk) of individual cells. Scale bars (A), (B) 50 μm and (C) 25 μm. Serial sections were also co‐immunostained for (D) ER‐TR7, FVIII, and SMA (white × marks negative cells) or (E) ER‐TR7 and osteocalcin OC; scale bars (D)−(E) 10 μm.

Image caption:
ER‐TR7 is upregulated during neonatal and adult digit tip blastema formation. ER‐TR7 (red) expression following digit tip amputation of PN3 neonates and 8W adult mice was detected by indirect immunofluorescence counterstained with DAPI (gray), captured at 100× magnification (scale bar 50 μmn . N= 4 animals per group). Images of select timepoints prior to and following amputation are shown for both (A)−(C) neonates and (E)−(G) adult mouse digit tips. The amputation level for both (A) neonate and (E) adult UA0 digits is marked by a yellow line. Scale bars (A)−(D) and (F)−(I) 50 μm.

Image caption:
Expansion of ER‐TR7+ FRCs is specific to the blastema stage. In representative (A) UA8 and (C) DPA8 samples, these areas are flanked by the nail bed (nb) and the P3 bone (b) and outlined with a dotted white line (scale bar 50 μm). Proliferating (Ki67+) cells were grouped by ER‐TR7+ or ER‐TR7− expression. (A), (C), insets: ER‐TR7+/Ki67+ cells were discriminated at 1000× magnification and are labeled with white + signs. ER‐TR7−/Ki67+ cells are marked with a − sign (scale bar 10 μm).

ER‐TR7 shares an expression trend with COL3. Representative
(A)−(C) UA8 samples from groups co‐stained for ER‐TR7 and COL3. Shown are individual (A) COL3 and (B) ER‐TR7 channels in grayscale with (C) merged with DAPI color images (scale bar 100 μm). (C) insert: Z‐stack captured from region of interest at 600× magnification (white‐outlined rectangles on corresponding low magnification image) in UA8 sample was rendered in 3D format to depict the subcellular distribution of the markers (grid 10 μm). The trend between the two antigens in vivo was measured by PCC‐based analysis with mean ± SE values (n = 4) shown on corresponding (C) merged channel images, where +1.0 is equivalent to a perfect trend and −1.0 equivalent to an absolutely opposite trend.

Image caption:
Co‐IHC localization studies on P3 cells co‐treated with TNFα and anti‐LTβR. Co‐localization analysis based on the PCC approach over eight high resolution photomicrographs at 400× magnification from each culture was performed (Fig. S3). Trends in localization and intensity level for these two antigens in both uninduced (Fig. S3A−C) and treated (Fig. S3D−F) P3 cells were almost identical gauged by our qualitative observations and strong pixel correlation measurements with overall mean r p values above 0.8.

Rat anti Mouse ER-TR7 antibody, clone ER-TR7 recognizes ER-TR7, an antigen that is located in the cytoplasm of reticular fibroblasts and is a component of the extracellular matrix of lymphoid and non-lymphoid organs. The antigen recognized by clone ER-TR7 has not been identified but studies suggest that it is likely to be distinct from laminin, fibronectin, collagen types I-IV, heparin sulphate proteoglycan, entactin and nidogen. Clone ER-TR7 has been used to stain the microanatomy of various organs and also stains subendothelial deposits in atherosclerotic plaques.
