doi: 10.1095/biolreprod51.4.739

Figure Lengend Snippet: FIG. 1. Immunofluorescence of CD44 in human endometrium. a) Proliferative phase tissue (mAb P3H9) showing immunoreactivity in epithelial cells in a gland as well as in surrounding stroma. b) Decidua of first trimester (mAb P3H9) with strong reactivity in decidual stromal cells. c) Late secretory phase tissue (mAb PIG12) showing lateral staining in gland cells. Gland lumen is to right of the field. d) Nuclear staining in same sections as c. e) Example of tissue (late secretory phase) in which stromal reactivity is present but many glands are unstained (mAb PIG12). Note that one gland at bottom right is immunopositive. f) Nuclear staining, same field as (e). Arrowheads in a, c, and e indicate the apical cell surface of glandular epithelium.

Article Title: Epithelial membrane protein 3 regulates lung cancer stem cells via the TGF‑β signaling pathway.

doi: 10.3892/ijo.2021.5261

Figure Lengend Snippet: Figure 2. EMP3 regulates CSC properties in lung CSC. (A) Western blot analysis of the CSC marker proteins CD133, ALDH1A1, ALDH1A3 and CD44. The CSC regulatory proteins Sox2, Oct‑4 and Nanog were also analyzed by western blotting. A549 cells were transfected with siRNA targeting EMP3. (B) Immunocytochemistry analysis of CSC marker proteins using siRNA treated A549 cells. The green signal is produced by the GFP tag on the secondary antibody. (C) Sphere‑forming capacity analysis of A549 cells in siRNA transfected EMP3 cells and (D) the ability to of an anti‑EMP3 antibody to abrogate sphere formation was assessed. (E) Single‑cell assay of si‑EMP3 transfected cells and (F) the ability of the anti‑EMP3 antibody to abrogate this. (G) Limiting dilution assays were performed in 96 well plates. Wells were plated with 1, 50, 100, 150 or 200 cells/well, and conditioned media was added. Results were confirmed 10 days after seeding of cells. Colony‑formation assays to observe the clonogenicity of the (H) EMP3‑knockdown A549 and (I) anti‑EMP3 antibody treated A549 cells. Cells were irradiated with 3 Gy radiation. After 10 days of incubation, the colonies were stained with crystal violet. (J) Western blot analysis of members of the Sonic hedgehog, Wnt/β‑catenin and Notch signaling pathways in CSCs. Data are presented as the mean ± standard deviation of three repeats. Scale bar, 50 µm. *P<0.05 vs. control. EMP3, epithelial membrane protein 3; ALDH1, aldehyde dehydrogenase 1; CSC, cancer stem cell; Sox2, sex determining region Y‑box 2; Oct‑4, octamer‑binding transcription factor 4; siRNA, small interfering RNA; p, phosphorylated; GSK3‑β, glycogen synthase kinase 3‑β.
