Micropatterns were incubated in extracellular imaging buffer (130 mM sodium chloride, 5 mM potassium chloride, 1.5 mM calcium chloride, 1 mM magnesium chloride, 25 mM 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES), 1 mg/mL BSA, and 5 mM glucose, with the pH adjusted to 7.4) with 10 nM tetramethylrhodamine methyl ester (TMRM, Life Technologies) for 45 min, and imaged in the same dye-containing buffer using a Nikon Eclipse Ti inverted microscope, using a Nikon Plan Fluor 10× objective with a numerical aperture (NA) of 0.30 (for unconfined micropatterns) or a Nikon Plan Apo 20× objective with 0.75 NA (for confined micropatterns). A Nikon C2 confocal microscope (Nikon Plan Apo 60× oil immersion objective, 1.40 NA) was used for confocal imaging.

Cells were seeded in a 24 well culture plate (Greiner) at a density of 1.5 × 104 cells/well on hydrogels or polystyrene in full DMEM/F12 media and incubated for 5 days at 37 °C, 5% CO2 in automated cell culture and the analysis system Cell-IQ® (CM Technologies Oy, Tampere, Finland). Cells were visualized by phase contrast using Nikon Plan Fluor 10× objective (NA 0.30). Each visual field was visualized for 4 h. Cell migration activity was measured using the Cell-IQ Analyzer software.

Cell Morphology Analysis with siRNA

The analysis of cell morphology was carried out as previously described [13 (link)]. Briefly, a 96-well plate was coated with 40 µl of a 7.5 mg/ml Matrigel solution. Around 5 × 105 cells transfected with siRNA oligonucleotides 48 h before the assay were mixed with 7 mg/ml Matrigel solution and transferred into one of the wells in the Matrigel-coated plate. The plate was incubated at 37°C. After 2 h, 100 µl of appropriated medium without FCS was added to each well. Cells were incubated at 37°C for 24 h. Images were acquired using a Nikon TE2000-E microscope with a Plan Fluor 10× objective (Nikon) and a Hamamatsu Orca-ER digital camera.

2D Scratch Assay for Cell Migration

Check if the same lab product or an alternative is used in the 5 most similar protocols
The 2D scratch assay was performed according to previous report.31 (link) For measuring cell migration rate, a scratch assay will be used where cells will be cultured in a 6 well plate to form a confluent monolayer. A p200 pipet tip will be used to scrape the cell monolayer in a straight line to create an empty gap. Then the cells will be allowed for migration into the gap and imaged to track their migration rates. The cells were imaged on an inverted Nikon Eclipse Ti-E microscope using bright field microscopy. A Nikon Plan Fluor 10 × objective (Numerical aperture: 0.30, working distance: 16.0 mm) and a 12 V/100 W halogen lamp as light source was used. The output power of the light source was kept constant for all the imaging experiments and the exposure time of 30 ms was used to provide optimal contrast and brightness. Images were then recorded by a sCOMS camera (Dhyana 400BSI, Tucsen).

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.
