Embodiment 3
[0101] Example 3: Preparation of primary porcine fibroblasts
[0102] Primary porcine fibroblasts can be prepared by traditional enzymatic digestion, the steps are as follows:
[0103] 1) Quickly scrub the pig fetuses that were killed (within 10 hours after being killed) three times with 70% alcohol, and put them into PBS+double antibody solution;
[0104] 2) Rinse the pig fetus with PBS in the ultra-clean workbench, and remove the head, limbs and internal organs of the pig fetus;
[0105] 3) Mince the pig fetal tissue treated in step 2) in a 60mm diameter plate, transfer the tissue fragments to a 50mL Erlenmeyer flask, and further chop into 1mm 3 Small fragments, take a small amount of tissue fragments and spread them on a 100mm Petri dish, add 10mL of culture medium (DMEM+15%FBS+double antibody), put in CO 2 Cultivate in an incubator (tissue block attachment method); add 3-5mL 0.25% trypsin digestion solution preheated at 39°C to the rest of the tissue fragments, put in CO...
