A Melanoma Patient-Derived Xenograft Model

Patient-derived xenograft (PDX) models more robustly recapitulate melanoma molecular and biological features and are more predictive of therapy response compared to traditional plastic tissue culture-based assays. Here we describe our standard operating protocol for the establishment of new PDX models and the characterization/experimentation of existing PDX...

Frozen Skin Tissue Block Preparation: A Protocol to Preserve Cutaneous Melanoma Samples from Murine Dorsal Skin

This video describes the detailed protocol for isolating melanoma-containing murine dorsal skin, followed by cryo-embedding to prepare a frozen skin tissue block. The cryo-embedded tissue block can be sectioned and microscopically examined to study melanoma...

Patient Derived Cell Culture and Isolation of CD133+ Putative Cancer Stem Cells from Melanoma12:16

Patient Derived Cell Culture and Isolation of CD133+ Putative Cancer Stem Cells from Melanoma

This article describes the preparation of freshly obtained melanoma tissue into primary cell cultures, and how to remove contaminations of erythrocytes and fibroblasts from the tumor cells. Finally, we describe how CD133+ putative melanoma stem cells are sorted from the CD133- bulk using Magnetic Activated Cell Sorting...

Unveiling Therapeutic Opportunities with Melanoma Patient-derived Organoid Models

Here, we present a protocol to generate melanoma patient-derived organoids by culturing disassociated cell suspensions from fresh melanoma tissues. These organoids faithfully recapitulate patient-specific tumors in vitro, offering an innovative approach to exploring tumor immunosuppressive mechanisms, drug screening, drug resistance mechanisms, and cancer surveillance approaches.

Patient-derived Xenograft Modeling: A Technique to Generate Melanoma Mouse Models

In this video, human-derived melanoma cells are implanted subcutaneously into the flank region of an immunocompromised mouse. The PDX model allows preclinical investigation of melanoma cells that better recapitulate the tumor heterogeneity and melanoma aggressiveness observed in in vivo...
