靶点: |
AhR;Aryl Hydrocarbon Receptor;AhR;ArylHydrocarbonReceptor |
体外研究: |
在NOD.Cg-Prkdcscid Il2rgtm1Wj1 / SzJ(NSG)小鼠中,通过SR1促进CB CD34 +细胞的增殖,能够有助于在早期进行细胞植入及持续植入 |
体内研究: |
在体外,StemRegenin 1(1 μM)能够促进CD34 +细胞的增殖(EC 50=?120 nM),同时降低VentX的表达水平。StemRegenin 1能够抑制光亲和配体(PAL)结合(IC 50 = 40 nM) |
细胞实验: |
StemRegenin 1 (SR1) is prepared in DMSO and stored, and then diluted with appropriate medium before use. A quantity of 250,000 CB-derived CD34+ cells are cultured with control conditions (DMSO, 0.01%) or StemRegenin 1 (0.75 μM) for 3 weeks. At this point control cultures had expanded 1080-fold and StemRegenin 1 treated cells expanded 2024-fold relative to starting cell numbers. A quantity of 30 to 30,000 uncultured CD34+ CB-derived cells or a fraction of the final culture equivalent to 30 to 10,000 starting cells are transplanted. The cells are injected intravenously via the retro-orbital route into sub-lethally irradiated (300 rads, 200 rads) 6- to 10-week-old NSG mice. Engraftment is performed within 24 h after irradiation. Engraftment is monitored by flow cytometric analysis of blood obtained via retro-orbital sinus or bone marrow using anti-human CD45 and anti-mouse CD45 antibodies. The mice are sacrificed between 13-16 weeks posttransplantation; bone marrow (from both femurs and tibiae), spleen and thymu |
