Figure Lengend Snippet: Expression profiles of limbal stromal (LS) at passage 6 and corneal stromal (CS) cells at passage 4 by FACS analysis. The two populations of cells have very similar expression where they expressed mesenchymal markers and absence of hematopoietic markers and endothelial marker (CD31). The cells did not express ABCG2 and other embryonic stem cells markers. The green line in the histograms represents the isotype controls.

Article Snippet: Embryonic stem cell line, BG01V (ATCC) at passage 16 were cultured on mitomycin treated MEF cells (ATCC) with 80% knockout DMEM supplemented with 20% Gibco knockout SR, 1% MEM-non essential amino acid (NEAA), 1% Glutamax, 0.1 mM B-mercaptoethanol (BME), 10 IU/ml penicillin, 10 μg/ml streptomycin (all from Invitrogen Corporation), and 4 ng/ml human basic fibroblast growth factor (bFGF; BD Biosciences) [ ].

Figure Lengend Snippet: ( A ) Bar graph showing GM-CSF expression in non-transduced and retrovirally transduced STO fibroblasts. Error bars represent mean ± SD. *, p<0.05; relative to non-transduced STO cells; t test. ( B ) Scheme of immunization. Male C57BL/6 mice were immunized twice (days 0 and 14) with HBSS (control), or irradiated 1×10 6 ESC+irradiated 1×10 6 GM-CSF-expressing STO murine embryonic fibroblasts (STO-GM) s.c. in the right flank. Seven days after boost, mice were challenged with 1×10 5 Lewis lung carcinoma cells (LLC) s.c. in the left flank. ( C ) C57BL/6 mice (10/group) were immunized twice (days 0 and 14) with HBSS (control), or irradiated 1×10 6 ESC+irradiated 1×10 6 STO-GM, or irradiated 1×10 6 STO-GM cells alone s.c. in the right flank prior to s.c. challenge with LLC on day 21. Tumor growth was monitored daily in all animals until sacrifice due to tumors exceeding 5% of body weight. The vaccinated tumor free mice remained so for up to 4 months later with no overt signs of distress or autoimmunity. are representative of three independent experiments. **, p <0.001; relative to control group; log-rank test. ( D ). Tumor growth was measured by calipers every 2nd or 3rd day and tumor volumes were plotted as indicated. The data represent the average tumor volumes of 10 mice/control group and 3 mice/ESC/STO-GM group and are representative of three independent experiments. Error bars represent mean ± SEM.

Article Snippet: As a vaccine, we employed the murine embryonic stem cell (ESC) line, ES-D3 (ATCC CRL-11632), derived from 129/Sv mice (expressing MHC class II I-E).
