Wound-Healing Assay for Cancer Cell Migration

Check if the same lab product or an alternative is used in the 5 most similar protocols
A wound-healing assay was performed to examine the capability of cancer cell migration, as previously described40 (link). Briefly, GC cells were grown in 24-well plates with RPMI-1640 medium supplemented with 10% FBS up to 90% confluence. A single scratch wound was generated with a 10 μL pipette tip. After removing the suspension cells by washing with PBS, fresh RPMI-1640 medium without FBS was added. With a Live Cell Imaging System (ZEISS, Germany), moving and growing of cells across the scratched lines were monitored every hour for 24 h. The migratory ability of the cells was presented as the gap distance recovered compared with the original gap.

Cell Migration Assay Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
GC cells were grown in 24-well plates with RPMI-1640 medium supplemented with 10% FBS until 90% confluence. Wounds were created by scratching the cell surface with a 10 μL pipette tip. After washing with PBS, fresh RPMI-1640 medium without FBS was added. Cells moving and growing across the scratched lines were monitored every hour for 24 h using a Live Cell Imaging System (ZEISS, Germany). The migratory ability of the cells was quantified as the gap distance recovered compared with the original gap.

Mitotic Morphology Characterization

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were stained with NucSpot Live Cell Nuclear Stains (#40082, BIOTIUM, Fremont, CA). Washings were with phosphate buffered saline (PBS) before plating in RPMI 1640 media supplemented with 10% FBS with antimycotics and antibiotics. Cells were maintained in the microscope chamber at 37°C and 5% CO2. Stained cells were scored for mitotic figures that were bipolar, or those having ring-like chromosomal structures or multipolarity division using a ZEISS Axiocam 506 color microscope and the Live-Cell Imaging system (Carl Zeiss Microscopy LLC, White Plains, NY).

Live Imaging of Glioma Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Glioma cells were transduced with the H2B‐GFP fusion protein using the lentivirus vector pCDH‐CMV‐MCS‐EF1‐Puro, and positive cells were sorted using flow cytometry. Then, the cells were plated in six‐well plates and incubated overnight. The plates were incubated in a live cell imaging system (Zeiss) with normal culture conditions. Images were captured every 5 min for 48 h and were processed and analyzed by AxioVision software (Zeiss).

Hydrogel Extraction Effect on HSF Cell Morphology

Check if the same lab product or an alternative is used in the 5 most similar protocols
HSF cells were cultured with hydrogel extraction solutions (pH 3, 7.4 and 8.5) in a 24-well plate (104 cells/well) for 24 h. After that, the medium was removed and washed with 1X PBS buffer to remove unattached cells. After the washing procedure, 2 mL 4 % paraformaldehyde in PBS was added into each well for 15 min to fixed cells, and the cells were washed with 1X PBS buffer three times. Then 1 mL 1 % BSA was added into each well to incubate at 37 °C for 30 min. BSA was removed and washed by 1X PBS buffer. Finally, diluted rhodamine phalloidin (100 μL, 1 μg/mL) was added into each well for 1 h and DAPI (100 μL, 0.5 μg/mL) was added into each well for 3 min, respectively. The cell morphology was observed by a Live Cell Imaging System (Zeiss Cell Observer).

Coculture of CNE-2 and GFP-Akata Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
CNE-2 or NEPC-Bmi1 cells pre-stained with CellTracker Red were planted in 35-mm confocal dish at 1 × 104 cells per well in RPMI 1640 medium containing 10% FBS. After 12 h, the culture medium was removed and GFP-Akata or AK31 cells at 1 × 105 cells in 1 ml culture medium were added into the dish. Cells were incubated at 37 °C with 5% CO2. After 4 h co-culture, non-adherent GFP-Akata cells were removed, followed by live cell Imaging System (Carl Zeiss Inc) observation for 12-72 h.

Immunofluorescence Localization of CXCR7 in Tissues

Check if the same lab product or an alternative is used in the 5 most similar protocols
Immunofluorescence staining was used to determine the location of CXCR7. Briefly, the tissue sections were fixed with 4% paraformaldehyde for 30 min. After treatment with 0.6% Triton X‐100 for 1 hr, the sections were blocked with donkey serum. Then, the sections were incubated overnight at 4°C with primary antibodies including anti‐CXCR7 (1:200, Abcam, ab137485) and anti‐vWF (1:200, Abcam, ab154193), followed by incubating with Alexa Fluor 488‐ or 568‐conjugated secondary antibody was added (1:500, Life Technologies). Samples were then co‐stained with DAPI (Sigma‐Aldrich) for 15 min at room temperature. Cover glasses were mounted with aqueous mounting medium (Sigma‐Aldrich, F4680). The images were obtained using a Zeiss Live Cell Imaging System.

Corneal Epithelial Cell Apoptosis

Check if the same lab product or an alternative is used in the 5 most similar protocols
The cells were irradiated with 144-mJ/cm 2 UVB for 2 h and then cultured in the Live Cell Imaging System (Zeiss) at 37°C with 5% CO 2 for 0, 6, and 12 h such that the experimental groups were called "I (2h) + C (0 h)," "I (2h) + C (6 h)," and "I (2h) + C (12 h)." The morphological changes in the corneal epithelial cells after irradiation at 0, 6, and 12 h were recorded using a differential interference contrast microscope (Zeiss). Then, 100 cells were chosen randomly, and the numbers of the different kinds of apoptotic cells were counted using the ImageJ software (National Institutes of Health, MD, USA).

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.
