Circulating tumour cell (CTC)-derived organoids are changing cancer research, providing scientists with a powerful tool for studying drug resistance and informing the development of new personalised therapies.
Circulating tumour cells (CTCs) are malignant cells that detach from primary or metastatic tumours and enter the bloodstream. As a central component of liquid biopsy, they provide real-time insights into tumour metastasis, the effectiveness of therapies and opportunities for personalising therapies.
What are CTC-derived Organoids?
Recently, researchers have succeeded in generating organoids from CTCs – miniature, three-dimensional tumour models that replicate key features of the original cancer. These organoids are fast becoming powerful tools for investigating metastasis and testing potential therapies.However, the field still faces major hurdles.CTCs are very rare, difficult to isolate and challenging to grow in culture – which means that success rates in constructing reliable models remain low.
A key feature of CTCs is their heterogeneity. Their surface markers and molecular traits vary from patient to patient. One of the most important challenges is capturing this diversity in organoid models.
The Meaning of CTC Heterogeneity
The variability in CTC characteristics has significant implications for treatment response. Different CTC subtypes may exhibit varying sensitivities to different drugs. Therefore,understanding this heterogeneity is crucial for developing personalized cancer therapies.
Challenges in CTC Isolation and Culture
- Rarity: CTCs are present in extremely low numbers in the bloodstream.
- Isolation: Efficient
