The transplantation of cancer cells is an important tool for the identification of cancer mechanisms and therapeutic responses. Current techniques depend on immune-incompetent animals. Here, we describe a method to transplant zebrafish tumor cells into immune-competent embryos for the long-term analysis of tumor cell behavior and in vivo drug responses.

We present a simple agarose overlay platform to grow 3D multicellular spheroids using neuroendocrine cancer cell lines. This method provides a very convenient way to examine the effect of therapeutic drugs on the neuroendocrine tumor cells. It could also help us establish human neuroendocrine tumor spheroids for cancer therapy.

We describe a novel in vivo imaging technique that couples fluorescent chimeric mice with intracranial windows and high-resolution 2-photon microscopy. This imaging platform aids studies of dynamic changes in brain tissue and microvasculature, at a single-cell level, following pathological insults and is adaptable to assess intracranial drug delivery and distribution.

The goal of this protocol is to study breast tumorigenesis. With this technique, mouse mammary tumors are removed and primary cells are prepared from tumors. A lung extraction protocol is included for studying lung metastasis. Furthermore, another protocol for analyzing mouse embryonic fibroblasts from the mouse embryo is included.
FAQs
Repeated observations allow researchers to connect changes within the same tumor to later outcomes rather than relying on a single snapshot. Tracking tumor size, cellular features, molecular profiles, or clinical status over time can clarify whether a change reflects progression, treatment response, delayed effects, or recurrence. This temporal linkage helps distinguish transient findings from sustained disease patterns.
Extended follow-up can expose delayed treatment effects, gradual therapeutic resistance, relapse, and changing interactions between a tumor and its surrounding tissues. These events may not appear during a brief observation window. Their inclusion gives cancer researchers a broader picture of disease behavior and helps explain why an initially responsive tumor may later progress or return.
Different measurements provide complementary evidence about what is happening over time. Tumor size can indicate physical growth or reduction, while cellular features and molecular profiles may show biological changes associated with progression or treatment response. Clinical status adds patient-level context. Linking these observations across time points supports a more informed interpretation than using any single measurement alone.
A treatment response observed early may not represent the eventual course of disease. Continued observation can identify effects that emerge later and reveal when a tumor becomes less responsive. Recording these patterns helps researchers characterize treatment durability, recognize resistance, and evaluate whether apparent benefit persists, changes, or is followed by recurrence.
Researchers use this approach when they need to understand how tumors change beyond an initial experimental or treatment period. It is especially relevant for examining progression, therapeutic response, recurrence, and the relationship between tumor behavior and surrounding tissues. The resulting observations can support disease modeling and help identify factors associated with different outcomes.
Longitudinal findings can identify prognostic factors, meaning features associated with how disease is likely to progress or respond. They also reveal patterns that inform disease models and expose limitations in short-term treatment evaluation. In cancer research, this evidence can guide the development of therapies intended to be more durable and precisely targeted.
