    Summary

    The bone marrow (BM) cell culture assay demonstrated a 100% correlation with in vivo tests for predicting anticancer drug efficacy. This assay shows promise for personalized cancer chemotherapy and drug screening.

    Area of Science:

    • Oncology
    • Cell Biology
    • Pharmacology

    Background:

    • In vitro assays for cloning tumor cells in soft agar have advanced.
    • Two assays are proposed for screening anticancer drugs and personalized chemotherapy.

    Purpose of the Study:

    • To evaluate three soft agar cloning assays: Toshio Kuroki (TK), Hamburger and Salmon (HS), and bone marrow (BM) cell cultures.
    • To assess the growth capacity and colony formation of various cell types in these assays.

    Main Methods:

    • Tested cells from 10 established malignant/non-malignant lines.
    • Utilized cells freshly derived from two tumors and five tumors after monolayer culture.
    • Compared colony formation across TK, HS, and BM assays.

    Main Results:

    • The bone marrow (BM) assay yielded the best results.
    • A 100% correlation between in vivo and in vitro results was observed with the BM assay.
    • Ongoing research explores the BM assay's potential as a transformation assay.

    Conclusions:

    • The BM assay is a highly accurate in vitro system for predicting in vivo tumor cell behavior.
    • This assay holds significant potential for anticancer drug screening and developing individualized cancer treatment strategies.
