In contrast, in the treatment group receiving AMD3100, FDA-approved Compound Library<\/a> leukemic cell cluster regrowth was inhibited in the portal area . As a result, the macroscopic size of the liver and spleen in AMD3100-treated leukemic mice was smaller than that in control mice , and leukemic cell counts and organ volumes of the liver and spleen were significantly reduced . Interestingly, the largest decrease in leukemic cell count was observed in the liver of AMD3100-treated mice , and was seemingly correlated to the frequency of CXCR4-positive leukemic cells in each organ . During the long-term administration of AMD3100 or NS up to 60 days after AraC treatment, significantly fewer leukemic cells were present in the PB of AMD3100-treated mice compared with control mice receiving NS . Consequently, the control mice lost a significant amount of body weight, while the body weight of the AMD3100-treated mice was not significantly different compared with that of normal NOG mice . Furthermore, the AMD3100-treated mice demonstrated a higher overall survival, as estimated by the Kaplan-Meier method . Overall, these results strongly indicate that the SDF-1\/CXCR4 signaling pathway plays a crucial role in re-expansion of ALL leukemic cells in the hepatic niche after chemotherapy and provide a novel anti-leukemic therapy that targets the extramedullary microenvironment. In this paper, we propose that leukemic extramedullary DAPT citations<\/a> pathology is due to not only migrating, but also resident proliferating leukemic cells in the extramedullary niche. Using xeno-transplantation model, previous reports showed that human leukemic cells infiltrate the liver ; however, those reports lacked pathological or molecular assessment. Here, through the analysis of h-leukemic NOG model, we have demonstrated that hepatic extramedullary microenvironments provide a niche which harbors and propagates leukemic cells. We also demonstrated that the SDF-1\/CXCR4 axis plays a crucial role in causing liver pathology. Recent studies revealed SDF- 1\/CXCR4 axis involvement in the development and metastasis of solid tumor . This axis has also been known to play an indispensable role in the homing, proliferation, and survival of both normal hematopoietic and leukemic cells in the BM niche . In pediatric ALL patients, high expression of CXCR4 in leukemic cells was strongly predictive of extramedullary organ involvement , which is compatible with the findings in our murine xeno-transplantation model.<\/p>\n","protected":false},"excerpt":{"rendered":"
