We present longitudinal time-lapse drug-response imaging of tumor spheroids using a combined cell cultivation chamber and dynamic optical coherence tomography (DOCT) microscope. The OCT-integrated cultivation chamber supplies the spheroid with 5 % CO₂ and keep its temperature at 37 ℃. This integrated system enables imaging a single sample with an arbitrary number of time points, and hence it enabled spheroid-drug-response assessment with high-time-resolution and small number of samples. The longitudinal DOCT patterns of non-treated and doxorubicin (DOX-) treated human breast cancer (MCF-7) spheroids have been successfully obtained over 100 hours.
