简介：
Overview
Culturing circulating tumor cells (CTCs) enables a detailed functional characterization of cancer, including the assessment of specific marker expression and drug resistance. This approach may serve as a promising clinical tool for personalized medicine, potentially improving patient outcomes.
Key Study Components
Area of Science
- Oncology
- Cell Biology
