Embodiment 1
[0047] 1. Configuration of complete medium
[0048] The complete medium is added in the serum medium EGM2: 10% (V / V) fetal bovine serum (FBS), 10ng / mL vascular endothelial growth factor VEGF, 0.4‰ (V / V) glucocorticoid, 1‰ (V / V) vitamin C, 1‰ (V / V) epidermal growth factor EGF, 5ng / mL basic fibroblast growth factor bFGF, 2ng / mL colony-stimulating factor (CSF), 1‰ (V / V) platelet source Sexual growth factor PDGF.
[0049] 2. Isolation and culture of mouse bone marrow mononuclear cells
[0050] The experimental animals were anesthetized by intraperitoneal injection of 10% chloral hydrate (0.3 mL / 100 g). The mouse femur was taken under aseptic conditions, and the bone marrow was quickly and completely washed into a centrifuge tube with PBS, and the erythrocyte lysate was slowly added in a ratio of 1:5 after pipetting evenly. Bone marrow mononuclear cells were isolated after centrifugation at 1000rpm for 5min. After washing 3 times with PBS, mononuclear cells were separated into...
Embodiment 2
[0057] This example provides a method for culturing bone marrow-derived endothelial progenitor cells. The difference between this method and Example 1 is that the composition of the medium used is: EGM2+5%FBS+Hydrocortisone+Ascorbic Acid+EGF+VEGF+IGF +FGF. Specifically, 5% (v / v) fetal bovine serum FBS, 10ng / mL Hydrocortisone (glucocorticoid), 0.4‰ (V / V) Ascorbic Acid, 2‰ EGF, 2ng / mL were added to the EGM2 medium. mL of VEGF, 5ng / mL of IGF, 1‰ (V / V) of FGF. The obtained endothelial progenitor cells are cultured by this culture method for a total of 6 generations, and after 6 generations, the state of the cells is relatively poor, and the cells grow very slowly.
Embodiment 3
[0059] This example provides a method for culturing bone marrow-derived endothelial progenitor cells. The difference between this method and Example 1 is that no colony-stimulating factor CSF is added to the medium used. The endothelial progenitor cells are cultured by this culture method, and the obtained endothelial progenitor cells are passed down for 6 generations. After 6 generations, the cell state is poor, the speed of passage is slow, and there are many floating dead cells.
