A Quick Organoid Viability Measurement by Using Cyto3D® Live-Dead Assay Kit

Introduction Organoids are three-dimensional (3D) tiny, self-organized tissue structures that mimic an organ’s functional and structural features. These self-organized 3D structures can be used to replicate much of the complexity of an organ. Compared to 2D monolayer cell cultures, organoids are becoming increasingly popular among research communities due to physiological similarities to intact tissues and […]

Patient-Derived Xenograft Using Xeno-Free VitroGel System in Comparison to Animal-based Matrigel

Introduction Patient-derived xenografts are becoming state-of-the-art for studying tumor behavior and drug responsiveness in a salient environment1. A patient-derived xenograft (PDX) is obtained when a tumor sample is removed from a patient, implanted into an immunosuppressed murine host, and then queried for cellular or molecular characteristics that could be of therapeutic value to the patient. […]

Comparing the Xeno-Free VitroGel to Animal-Based Matrigel for Xenograft Studies

Introduction A cell-derived xenograft (CDX) model is the gold standard for anti-cancer therapies. The response of xenografts obtained in immune-deficient animals in drug testing is comparable to that in clinical practice, which makes xenograft models robust research tools in oncology1. In addition, over the past decades, patient-derived xenograft (PDX) models have emerged for precision medicine […]
