Abstract: Described in exemplary embodiments herein are methods, compositions, and kits for diagnosing, prognosing, monitoring, treating and/or preventing a hemopoietic malignancy and/or relapse thereof in a subject. In some embodiments, the methods can include determining an average cellular mass of cells in a sample from the subject and/or detecting one or more molecular signatures in one or more of the cells. In some embodiments, treatment includes administering one or more BCR-ABL tyrosine kinase inhibitors or a pharmaceutical formulation thereof, one or more pre-BCR signaling pathway inhibitors or a pharmaceutical formulation thereof, one or more p38 MAPK inhibitors or a pharmaceutical formulation thereof; or any combination thereof.

Abstract: In certain example embodiments, the invention provides a method of generating an ex vivo cell-based system comprising dissociating an original tissue sample obtained from a subject into a single cell population; determining an in vivo phenotype of the tissue sample by conducting single-cell RNA analysis on a first portion of the single cells; establishing an ex vivo cell-based system from a second portion of the single cells; and culturing the ex vivo cell-based system in a medium or conditions selected to maintain the in vivo phenotype. In some embodiments, the original tissue sample is a tumor tissue sample, such as a pancreatic ductal adenocarcinoma (PDAC) tumor sample.
