Embodiment 1
[0059] Embodiment 1 of the present invention provides a detection method for mesenchymal stem cells inhibiting lymphocyte proliferation in vitro, specifically as follows:
[0060] (1) MSC cell inoculation: take 400g cell suspension, centrifuge for 5min, remove the supernatant, add Gibco 1640 medium containing 10wt% fetal bovine serum to resuspend, sample and count; according to the counting result, adjust the cell concentration to 2×10 5 / mL; Inoculate the adjusted cell suspension in three 24-well culture plates, inoculate 4 wells in each plate, 500 μL in each well, and inoculate 12 wells in total. Place the inoculated cell plates in a carbon dioxide incubator (CO 2 The concentration is set to: 5.0vol%, the temperature is set to: 37.0°C), and cultured for 20 hours;
[0061] (2) MSC cell deproliferation treatment: discard the medium in each well in step (1), add 500 μl of Gibco 1640 medium containing 8 μg / mL mitomycin C to each well and contain 10wt% fetal bovine serum, and pl...
Embodiment 2
[0065] Embodiment 2 of the present invention provides a detection method for mesenchymal stem cells inhibiting lymphocyte proliferation in vitro, specifically as follows:
[0066] (1) MSC cell inoculation: take 400g cell suspension, centrifuge for 5min, remove the supernatant, add Gibco 1640 medium containing 10wt% fetal bovine serum to resuspend, sample and count; according to the counting result, adjust the cell concentration to 2×10 5 / mL; Inoculate the adjusted cell suspension in three 24-well culture plates, inoculate 4 wells in each plate, 500 μL in each well, and inoculate 12 wells in total. Place the inoculated cell plates in a carbon dioxide incubator (CO 2 The concentration is set to: 5.0vol%, the temperature is set to: 37.0°C), and cultivated for 24 hours;
[0067] (2) MSC cell deproliferation treatment: discard the medium in each well in step (1), add 500 μl of Gibco 1640 medium containing 12 μg / mL mitomycin C to each well and contain 10wt% fetal bovine serum, and...
Embodiment 3
[0071] Embodiment 3 of the present invention provides a detection method for mesenchymal stem cells inhibiting lymphocyte proliferation in vitro, specifically as follows:
[0072] (1) MSC cell inoculation: take 400g cell suspension, centrifuge for 5min, remove the supernatant, add Gibco 1640 medium containing 10wt% fetal bovine serum to resuspend, sample and count; according to the counting result, adjust the cell concentration to 2×10 5 / mL; Inoculate the adjusted cell suspension in three 24-well culture plates, inoculate 4 wells in each plate, 500 μL in each well, and inoculate 12 wells in total. Place the inoculated cell plates in a carbon dioxide incubator (CO 2 The concentration is set to: 5.0vol%, the temperature is set to: 37.0°C), and cultured for 22 hours;
[0073] (2) MSC cell deproliferation treatment: suck and discard the medium in each well in step (1), add 500 μl of Gibco 1640 medium containing 10wt% fetal bovine serum containing 10 μg / mL mitomycin C to each wel...
