Практические соображения в изучении метастатического легких колонизации в остеосаркома, используя Assay легочных метастазов

Overview

This article describes the pulmonary metastasis assay (PuMA) protocol, which allows for the visualization and study of metastatic osteosarcoma cell growth in lung tissue. The method provides insights into how these cells adapt and proliferate in a three-dimensional microenvironment.
