Establishment and Application of 3-Dimensional (3-D) Cell Culture Model of Clinical Circulating Tumor Cells (CTCs)

Chang Gung Memorial Hospital·observational·Posted Nov 21, 2022·Updated Sep 24, 2025

In Brief

An observational study evaluating CTCs isolation/purification and cell number expansion for Cell Carcinoma. Completed, enrolled 160 participants across 1 site.

Detailed Summary

The goal of this observational study is to validate and evaluate the clinical feasibility of using a 3-D cell culture model for CTCs isolation/purification and their cell number expansion in cancer patient with transitional cell carcinoma and patient without cancer. This project first aims to study the clinical feasibility of utilizing a 3-D cell culture model for the isolation/purification of all possible CTCs in a blood sample in a label-free, viable, and high-purity manner. Through 3-D CTC culture, moreover, the cell number of CTCs can be adequately expanded. All these advantageous features are beyond what is currently possible by using the existing methods. In addition, the harvest of CTCs with above features is found valuable for the subsequent academic researches or clinical studies (e.g. molecular mechanisms underlying cancer metastasis, cancer-related gene mutation, biomarker discovery, and particularly CTCs-based chemotherapy drug testing). These could both facilitate and accelerate scientists to develop new therapeutic solutions for future cancer care.

Interventions

CTCs isolation/purification and cell number expansionprocedure

In the 1st year research project, investigators will further validate and evaluate the clinical feasibility of using a 3-D cell culture model for CTCs isolation/purification and their cell number expansion. In the 2nd and 3rd year research project, investigators will optimize the 3-D cell culture model so as to increase the performances of CTC isolation/purification and proliferation. In the optimization process, investigators will explore the effect of cell culture model (e.g. static or perfusion cell culture, and 3-D cell culture using different 3-D scaffolding materials) or biochemical factors (e.g. glucose concentration, serum concentration, pH, or the supplements of growth factors/cytokines) on the the performances of CTC isolation/purification and proliferation.
