Article Snippet: HIOECs at 3x10 4 cells/well were seeded in the 96-well plate and exposed to KGF (10 ng/mL; Proteintech) for 24 h. For MTT assays, the cells were incubated with 20 μL of MTT solution (5 mg/mL) at 37°C for 4 h. The supernatant was discarded, and 150 μL of dimethyl sulfoxide (DMSO) was added to each well.

Article Title: Basic Fibroblast Growth Factor Reduces Permeability and Apoptosis of Human Brain Microvascular Endothelial Cells in Response to Oxygen and Glucose Deprivation Followed by Reoxygenation via the Fibroblast Growth Factor Receptor 1 (FGFR1)/ERK Pathway

doi: 10.12659/msm.918626

Figure Lengend Snippet: Figure 3. Basic fibroblast growth factor (bFGF) reduced the increase in endothelial monolayer permeability and apoptosis induced by oxygen-glucose deprivation/reperfusion (OGD/R). (A) Treatment with bFGF significantly decreased the permeability of HBMECs 12 h after OGD/R treatment. (B) Quantification and (C) immunostaining of apoptotic cells 12 h post-OGD/R, as detected by the TUNEL assay. The number of immunoreactive cells was reduced by bFGF, indicating that it suppressed OGD/ R-induced HBMEC apoptosis. The control or bFGF group vs. the OGD/R group (** P<0.01). Inhibition of FGFR1 with PD173074 or inhibition of ERK with PD98059 compared with the bFGF group (## P<0.01). N=6 in each group. N=3 independent experiments.

Article Title: Basic Fibroblast Growth Factor Reduces Permeability and Apoptosis of Human Brain Microvascular Endothelial Cells in Response to Oxygen and Glucose Deprivation Followed by Reoxygenation via the Fibroblast Growth Factor Receptor 1 (FGFR1)/ERK Pathway

doi: 10.12659/msm.918626

Figure Lengend Snippet: Figure 4. Following oxygen-glucose deprivation/reperfusion (OGD/R) of endothelial cells, basic fibroblast growth factor (bFGF) inhibited the decrease in tight junction and adherens junction proteins. (A–D) Treatment with bFGF reversed or reduced zonula occludens-1 (ZO-1), occludin, claudin-5, and b-catenin expression in HBMECs 24 h after OGD/R treatment. Inhibition of fibroblast growth factor receptor 1 (FGFR1) with PD173074 and inhibition of ERK with PD98059 reversed the protective effect of bFGF.
