Adult male C57/BL6 mice and B6Nude mice (20–25 g) were housed under light- and temperature-controlled conditions. All experiments were conducted in compliance with the Association for Research in Vision and Ophthalmology (ARVO) Statement for the Use of Animals in Ophthalmic and Vision Research. The experimental protocol was approved by the Institutional Animal Care and Use Committee of Royan Institute.
Procured MSCs obtained from the RP patients, were injected into the mice vitreous cavities and the corresponding eyes were subjected to routine histopathologic and immunohistochemical studies. For immunofluorescence analysis, the sections were permeabilized with 0.3% Triton X-100 in phosphate-buffered saline (PBS) and blocked with normal secondary host serum. The sections were stained overnight with primary antibodies against specific anti-human Thy1 (Millipore, CBL415) and glial fibrillary acidic protein (GFAP; Sigma-Aldrich G3893). The stained sections were examined with a fluorescent microscope (Olympus, IX71, Japan) that had a DP72 digital camera following treatment with secondary antibodies: Goat anti-mouse Alexa-fluor 568 (Molecular Probes) or goat anti-mouse FITC (Sigma-Aldrich). Nuclei were stained with 4',6-diamidino-2-phenylindole (DAPI). A number of sections were stained with hematoxylin and eosin (H and E).

Check if the same lab product or an alternative is used in the 5 most similar protocols
To generate HeLa-Kyoto cells stably expressing biotinylated mTagBFP-tagged GCP2, cells were co-transduced with GCP2 and BirA lentivirus (Abella et al., 2016 (link)) followed by hygromycin and puromycin selection. Resistant cells expressing mTagBFP were sorted by FACS (fluorescent assisted cell sorter) and cultured independently in 96 well plates. The isolated single-cell colonies were screened for HA-BirA expression by immunofluorescence staining (primary antibody: mouse anti-HA (F-7, Santa Cruz Biotechnology); secondary antibody: goat anti-mouse-FITC (Sigma)) and then using high throughput imaging (High throughput screening facility, Francis Crick Institute). The localisation of GCP2-mTagBFP-BAP was confirmed by live-cell fluorescence imaging using a spinning disc confocal microscope based on a NikonTI-E frame with a 100x 1.49 N.A. Nikon objective lens (Cairn Research, Faversham, UK). mTagBFP expressing colonies were further tested by western blotting to confirm the expression of GCP2-mTagBFP-BAP and HA-BirA.
When producing large cell cultures for purification, three days before harvesting cells (using trypsination), D-biotin (Sigma Aldrich) was added to a final concentration of 50 μM. Cell pellets were stored at -80°C until further use.

After 5 days of cell culture, the samples were fixed in 4% paraformaldehyde solution (pH 7.4) for 15 min at room temperature and then permeabilized with 0.3% Triton™ X-100 (Sigma-Aldrich, USA) in PBS for 10 min at 4 °C. After three times of PBS washing, the samples were placed in a blocking buffer (5% normal goat serum and 1% bovine serum albumin in PBS-0.3% Triton-X100) for 1 h at room temperature. The samples were incubated with the diluted primary antibody solution containing mouse anti-ZO-1 (1:100; Thermo Fisher Scientific, USA) and rabbit anti-VE-cadherin (1:100; Cell Signaling Technology, USA), in a humidified chamber at 4 °C for overnight. The next day, the samples were washed with PBS 6 times, and secondary antibodies (goat anti-rabbit TRITC (1:400; Sigma-Aldrich, USA) and goat anti-mouse FITC (1:400; Sigma-Aldrich, USA) in the blocking buffer) were added. After 1 h of incubation in a dark chamber at 4 °C, the samples were washed 6 times with PBS, and the nuclei counterstaining was performed with DAPI (Sigma-Aldrich, USA) for 5 min. The samples were imaged with a confocal microscope (LSM 700, Carl Zeiss, Germany). The length and both angles of the major and minor axes of HUVECs were measured with ImageJ analysis software for the analysis of cell morphology in terms of aspect ratio and orientation angle.

For immunofluorescence, HUVECs were seeded on gelatin-coated glass cover slips plated in 24-well plates and transfected with corresponding siRNA amount as described above. The cells were grown overnight in ECGM with 10% FCS. After incubation in 0.5% FCS for 24 h, the cells were washed with PBS and fixed with 4% formaldehyde for 10 min at room temperature. Then, cells were incubated in the blocking and permeabilization buffer containing 2.5% BSA and 0.3% Triton X-100. Subsequently, the cells were incubated with primary antibodies overnight at 4 °C. After washing with PBS, cells were incubated with secondary antibodies conjugated with FITC or TRITC for 1 h at room temperature. Finally, the slides were washed and mounted with mowiol (Calbiochem, Germany). The primary antibodies were rabbit-anti-FoxO1 (Cell Signaling), goat-anti-Ang-2 (Santa Cruz) and mouse-anti-O-GlcNAc (Abcam). The secondary antibodies were swine anti-rabbit FITC (DakoCytomation), swine anti-rabbit TRITC (DakoCytomation, Glostrup, Denmark), goat anti-mouse-FITC (Sigma-Aldrich) and Donkey anti-goat FITC (Acris, OriGene Europe, Herford, Germany).

All samples were washed with PBS to remove any unattached cells and fixed in situ with 4% paraformaldehyde for 10 min at room temperature. Then, cells were permeabilized for 5 min with PBS containing 0.1% TritonX-100 and unspecific binding blocked with 2% BSA in PBS for 1 h. To visualize focal adhesions (FAs) or differentiation, cells were treated with the three primary antibodies, including mouse anti-vinculin antibody (Sigma; V9131; 1:300), mouse anti-types I collagen (Col-I) antibody (Abcam; ab6308; 1:200), or mouse anti-α-SMA antibody (Sigma; A5228; 1:200) at 4°C overnight, followed by incubation with goat anti-mouse-FITC (Sigma; F0257; 1:100) at 37°C for 1 h. Subsequently, F-actin was stained with phalloidin-TRITC (Cytoskeleton; PHDR1; 100nM) and the nucleus with DAPI (Thermo; P36931; undiluted).
All specimens were then examined under a fluorescence microscope (Carl Zeiss, Oberkochen, Germany) at low magnification (5× or 10×) or a laser scanning confocal microscopy (Nikon Co., Japan) at high magnification (40×). The fluorescent images were quantitatively analyzed using NIH ImageJ software.

Check if the same lab product or an alternative is used in the 5 most similar protocols
All animal studies were approved by the McGill University Animal Care Committee. Cardiotoxin (CTX) from Naja mossambica mossambica (Sigma) was prepared as a 10 μM solution in sterile saline. USP19 WT and KO mice (8 wk old; unpublished data) were anesthetized, and the hind legs were shaved and cleaned. Each TA muscle was injected with 50 μl CTX with a 28-gauge insulin syringe. When the animals were killed, one TA muscle was homogenized in 4 M guanidinium isothiocyanate, followed by phenol-chloroform extraction to isolate RNA, and the other was flash-frozen in isopentane for cryosectioning. cDNA was prepared with 750 ng RNA, and RT-PCR analysis was performed as described under RNA analysis by qPCR. TA muscles were sectioned at the midbelly in 9-µm sections and stained with hematoxylin and eosin. For cross-sectional area analysis, myofibers were visualized with anti-dystrophin antibody to identify the cell membrane and fluorescently labeled goat anti-mouse FITC (Sigma, St. Louis, MO) antibodies. Slides were visualized as described under Immunofluorescence but with 10× magnification. Approximately 200 myofibers with centrally located nuclei were analyzed per animal using ImageJ software.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
