0 × 106 cells/100 μL. The cell suspension (100 μL) was EtOH administered via the right femoral vein on day 7 after the cerebral embolism. Vehicle was injected in a similar manner as the NPCs. Bromodeoxyuridine labeling 5-Bromo-2′-deoxyuridine

(BrdU, Sigma-Aldrich) injection was used in this study to reveal the rate of generation of cells at specific time points after the embolism. In the experiments, rats were administered by the intraperitoneal route a single dose of BrdU (50 mg/kg) at 7 or 28 days after the embolism. Twenty-four hours after the administration, the high throughput screening animals were perfused transcardially with 4% paraformaldehyde Inhibitors,research,lifescience,medical under deep anesthesia. Histological assessments On day 7 or 28 after surgery, cerebrally embolized rats were perfused via the heart

with 4% paraformaldehyde in 0.1 mol/L phosphate buffer. Their brains were quickly removed and immersed in 30% sucrose in 0.1 mol/L phosphate buffer. The brains were then cut into 5-mm-thick Inhibitors,research,lifescience,medical coronal slabs, which were subsequently embedded in Neg50 (Richard-Allan Scientific, Kalamazoo, Inhibitors,research,lifescience,medical MI) and cut into 10-μm sections by using a cryostat. For immunostaining, sections were incubated overnight with the desired primary antibody at 4°C after blocking, and then with the corresponding secondary antibody for 1 h. In the case of double immunofluorescence staining, after a wash, the same sections were incubated overnight with another primary antibody at 4°C. Subsequently, they were incubated with the corresponding secondary antibody for 1 h. Omission of primary antibodies served as a negative control. No Inhibitors,research,lifescience,medical immunostaining was detected in this group. The following primary antibodies were used: rat monoclonal anti-BrdU (AbD Serotec, Oxford, U.K.), mouse monoclonal anti-rat endothelial cell antigen (RECA) (AbD Serotec, Oxford, Inhibitors,research,lifescience,medical U.K.), rabbit polyclonal Ang-1 (Abcam, Minneapolis, MN), rabbit polyclonal anti-GFAP (DAKO, Capinteria, CA), and rat monoclonal

anti-GFP (Nacalai Tesque, Kyoto, Japan). The secondary antibodies used were as follow: Alexa Fluor 488 chicken anti-rat IgG (Molecular Probes, Inc., Eugene, OR), Cy3-conjugated goat anti-mouse IgG (Amersham, Buckinghamshire, U.K.), and Cy3-conjugated donkey anti-rabbit IgG (Jackson ImmunoResearch). Fluorescence was detected by using an Olympus fluorescence microscope (BX-52; Olympus) or with a KEYENCE BZ-8000 (KEYENCE). Tissue Carfilzomib preparation On day 7 or 28 after surgery, cerebrally embolized or sham rats were sacrificed by decapitation. The whole ipsilateral hemisphere was homogenized in ice-cold buffer containing 320 mmol/L sucrose, 20 mmol/L β-glycerophosphate, 20 mmol/L sodium diphosphate, 0.2 mmol/L sodium orthovanadate, 0.1 mmol/L phenylmethyl sulfonyl fluoride, 5 μg/mL antipain, 5 μg/mL aprotinin, and 5 μg/mL leupeptin at 4°C.
