Experimental report:

1、 Separation and cultivation:

2、 Immunofluorescence identification:

1. Under sterile conditions, extract atrial tissue from 1-3 day old SD rats, wash the tissue block twice with PBS, and finally reduce it to a size of approximately 1mm3;
2. Add 4 mL of enzyme digestion solution (0.1% and 0.1% type I collagenase) to the tissue block, suspend for 10 seconds, digest at 37 ℃ for 10 minutes, then use a dropper to prepare a single-cell suspension, naturally precipitate and collect the supernatant, terminate digestion with 10% FBS medium, and place at 4 ℃;
3. Add 3-4mL of enzyme digestion solution to the remaining tissue, suspend for 10 seconds, digest at 37 ℃ for 10 minutes, collect the supernatant according to the above method, terminate digestion, and place at 4 ℃. Repeat this step 2-3 times until the tissue is digested;
4. Filter the cell digestion solution through a 200 mesh stainless steel sieve, centrifuge at 1200r/min for 10 minutes, discard the supernatant, and suspend the precipitated cells in DMEM/F12 medium containing 10% FBS. Inoculate the cells into a 25cm2 culture bottle and incubate in a 37 ℃, 5% CO2 incubator;
5. After 1 hour of differential adhesion, aspirate the culture medium and inoculate it into a 6-well plate as needed for further cultivation;

1. When the atrial myocytes grow to 80% fusion, discard the culture medium and wash the cells twice with warm PBS for 10 minutes each time. Then fix the cells with 4% paraformaldehyde at room temperature for 15 minutes;
2. Wash the cells twice with PBS for 10 minutes each time, and then permeate the membrane with 0.1% Triton X-100 at 4 ℃ for 15 minutes;
3. Wash the cells twice with PBS for 10 minutes each time, and then block the cells with 4% BSA at room temperature for 30 minutes;
4. Dilute the alpha actin primary antibody in a ratio of 1:100, and then incubate the cells overnight at 4 ℃ in a refrigerator;
5. Wash the cells with PBS three times, each time for 10 minutes. Dilute the secondary antibody against alpha actin in a ratio of 1:150 and place it at 37 ℃ for 1 hour;
6. Wash with PBS three times, each time for 10 minutes, and finally observe the image under an inverted fluorescence microscope and take photos.

Operating procedures:
1、 Preparation of culture medium and culture cryopreservation conditions:
1) Prepare RPMI-1640 medium, 90%; High quality fetal bovine serum, 10%.
2) Cultivation conditions: Gas phase: air, 95%; Carbon dioxide, 5%. Temperature: 37 ℃, humidity in the incubator is 70% -80%.
3) Cryogenic solution: 90% serum, 10% DMSO, ready to use and prepared, stored in liquid nitrogen.
2、 Cell processing:
1) Resuscitate cells: Quickly place a cryovial containing 1mL of cell suspension into a 37 ℃ water bath (with the water level lower than the lid of the cryovial) and shake to thaw. Transfer the cryovial into a 15ml centrifuge tube containing 4mL of culture medium prepared in advance and mix well. Centrifuge at 1000RPM for 4 minutes, discard the supernatant, add 1mL of culture medium and blow evenly. Then transfer all cell suspensions into a culture bottle containing 5ml of culture medium and culture overnight. The next day, change the solution and check the cell density.
2) Cell passage: If the cell density reaches 80% -90%, passage culture can be carried out.
For suspended cells, the following methods can be used for passaging:
Method 1: Collect cells,1000RPM， Centrifuge at room temperature for 5 minutes, discard the supernatant, add 1-2mL of culture medium and blow evenly. Divide the cell suspension into new dishes or bottles containing 8ml of culture medium in a ratio of 1:2 to 1:5.
