The first Japanese biobank of patient‐derived pediatric acute lymphoblastic leukemia xenograft models
A lack of practical resources in Japan has limited preclinical discovery and testing of therapies for pediatric relapsed and refractory acute lymphoblastic leukemia (ALL), which has poor outcomes. Here, we established 57 patient‐derived xenografts (PDXs) in NOD.Cg‐Prkdc ( scid ) ll2rg ( tm1Sug )/Shi...

Sumario: | A lack of practical resources in Japan has limited preclinical discovery and testing of therapies for pediatric relapsed and refractory acute lymphoblastic leukemia (ALL), which has poor outcomes. Here, we established 57 patient‐derived xenografts (PDXs) in NOD.Cg‐Prkdc ( scid ) ll2rg ( tm1Sug )/ShiJic (NOG) mice and created a biobank by preserving PDX cells including three extramedullary relapsed ALL PDXs. We demonstrated that our PDX mice and PDX cells mimicked the biological features of relapsed ALL and that PDX models reproduced treatment‐mediated clonal selection. Our PDX biobank is a useful scientific resource for capturing drug sensitivity features of pediatric patients with ALL, providing an essential tool for the development of targeted therapies. |
