    Chromatin Remodeling in Patient-Derived Colorectal Cancer Models

    The transcriptomic and chromatin accessibility landscapes of matched colorectal cancer patient-derived organoids (PDO), patient-derived xenografts (PDX), PDO-derived PDX, and original patient tumors were compared. Two major remodeling axes were discovered.

    Fabrication of a Coculture Organoid Model in the Biomimetic Matrix of Alginate to Investigate Breast Cancer Progression in a TAMs-Leading Immune Microenvironment

    A type of direct breast cancer cells–tumor-associated macrophages (TAMs) coculture organoid model was well developed by a sequential culture method in this study. Alginate cryogels were fabricated with appropriate physical and mechanical properties to serve as an alternative extracellular matrix.

    A Growth Factor-Reduced Culture System for Colorectal Cancer Organoids

    Researchers explored organoid culture recipes to capture tumor features of colorectal cancers. They found that the activation of Wnt and EGF signaling and inhibition of BMP signaling were non-essential for the survival of most colorectal cancer organoids.

    A Pair of Primary Colorectal Cancer-Derived and Corresponding Synchronous Liver Metastasis-Derived Organoid Cell Lines

    The authors presented paired 3D organoid cell lines of CWH22 and CLM22 with sound background information and the short tandem repeats were identical to those of the normal tissue.

    Comparing Stem Cells, Transdifferentiation, and Brain Organoids as Tools for Psychiatric Research

    The authors contrast advantages and disadvantages of each of these six cell-based methodologies. Neuronal-like cells derived from pluripotent monocytes are presented in more detail as this technique was recently used in psychiatry for the first time.
