This invention belongs to the fields of biotechnology and precision oncology, and discloses a serum-free amplification method for circulating tumor cells (CTCs) based on apoptosis selectivity, along with a dedicated culture medium. This addresses the problems of existing CTC technologies, which rely on physical capture leading to impaired cell viability and low culture success rates.
