Put 13 ml of cell culture medium inside the tube (see Table 1). The medium must fill at the least two cm above the cylindrical piece to make sure complete immersion of the sample. NOTE: For information of distinct cell kinds, along with other model systems for instance yeast or C. elegans embryos, plus the corresponding medium IL-4 Protein Molecular Weight applied, refer to section 5 and Table 1. The described protocol was optimized for HeLa, NIH3T3 cells, along with other cell lines (see Table 1). Introduce quite gently the `eggcups‘ inside the tube and parallel towards the upper side on the plastic piece. Use sharp tweezers to hold the sample using the PDMS handle. Press gently the coverslip until it lies on major from the upper side of the plastic piece, until it truly is totally immersed (see Figure 2). NOTE: It is actually suggested to use sharp and straight tweezers. With curved tweezers, the manipulation with the sample is challenging and could bring about breakage. Culture cells until 80-100 confluence inside a P60 Petri dish and gather them by trypsinization. NOTE: Cells is often wild-type, transfected or treated with any drug of interest. NOTE: Stay away from the formation of cell aggregates that will avoid single cells to enter the `eggcups’. To optimize this step, pipette up and down thoroughly soon after trypsinization. Re-suspend cells into five ml culture medium. Pipette 200 of cells on top on the `eggcups’. NOTE: Drop cells as centered as you can on prime of the `eggcups’ but avoiding physical get in touch with. This will likely stop breakage and/or harm in the sample. Centrifuge at 1,800 x g for two min. NOTE: Right after the initial centrifugation, verify within a microscope the filling percentage of your `eggcups’. Pipette once again 200 of cells on top in the `eggcups’ and centrifuge at 1,800 x g for two min. Repeat for any total of 3 times in an effort to optimize the filling percentage. NOTE: Right after the final centrifugation, check having a microscope the filling percentage of `eggcups’. If important, repeat the filling + centrifugation steps until reaching the desired filling percentage. Get rid of the sample in the tube employing the sharp tweezers holding the PDMS deal with. Ensure that to be cautious in not `disturbing’ cells that are held inside the `eggcups’ (see Figure 2). Location the sample within a Petri dish with medium. Rinse to get rid of the excess of cells that are not within the `eggcups’ by pipetting up and down 3 occasions gently next to each side (total four sides) on the microstructure array. NOTE: Pipetting also strongly may well release some cells out in the `eggcups’. Replace the medium with fresh medium to take away nonattached cells. NOTE: In this step a drug of interest is often added. Repair cells or prepare them for time-lapse imaging.See step 4.1.3. Observation of Active Cellular Dynamics in `Eggcups’: Cytokinetic Ring ClosureNOTE: This instance uses HeLa cells which are transfected with MYH10-GFP and Lifeact-mcherry for myosin and actin, respectively, essential active molecules involved in the cytokinetic ring closure through cell mitosis. The device is prepared with microcavities of 25 in diameter. For their observation, an epifluorescence inverted microscope was applied, equipped using a 60X oil objective (1.40 NA, DIC, Program Apo) and GFP (myosin) and TxRed (actin) filters. Alternatively an upright confocal microscope was utilised, equipped having a 25X or 63X HCX IR APO L water objective (0.95 NA). For this instance, it can be highly encouraged to synchronize cells by us.
