The primary cilium is fundamentally important in neural progenitor cell proliferation, neuronal differentiation, and adult neuronal function. Here, we describe a method to study ciliogenesis and the trafficking of signaling proteins to cilia in neural stem/progenitor cells and differentiated neurons using primary neurosphere cultures.

A protocol is described to extract primary human cells from surgical colon tumor and normal tissues. The isolated cells are then cultured on soft elastic substrates (polyacrylamide hydrogels) functionalized by an extracellular matrix protein, and embedded with fluorescent microbeads. Traction cytometry is performed to assess cellular contractile stresses.

Tumor Implantation and Injection of a Tumor Vaccine in a Mouse Model

This video demonstrates a cell-based tumor vaccination assay. A mouse, intradermally injected with B16-F10 melanoma cells for tumor formation, is vaccinated with B16-F10 cells secreting Flt3L cytokine near the developed tumor. The secreted Flt3L from the vaccine promotes the maturation and proliferation of dendritic cells that then present tumor antigens to T cells in lymph nodes, triggering a targeted anti-tumor immune response.
FAQs
Genetic and epigenetic changes can disrupt the controls that regulate cell division and survival. Together, these disturbances may permit continued proliferation and loss of normal tissue organization. Examining both types of change helps explain how abnormal growth becomes established and progresses within the tissue where the cancer begins.
The surrounding tissue is an active part of the biological setting in which a primary tumor grows. Tumor expansion can remodel this local environment and disrupt normal tissue organization, while interactions between abnormal cells and nearby tissue may accompany invasion. Studying these relationships helps explain why tumor behavior cannot be understood from abnormal cells alone.
Invasion indicates that abnormal cells are affecting more than the site of their initial growth. As the mass expands, cells may move into adjacent tissues and can eventually enter blood or lymphatic vessels. This behavior connects local tissue disruption with the possibility of distant secondary tumors, making invasion important for understanding how disease progresses.
Cellular composition and growth patterns provide information about how the tumor is organized and how it expands. When considered with interactions involving surrounding tissue, these features help researchers investigate cancer progression and interpret differences in diagnosis, prognosis, and treatment response. They also connect visible tumor characteristics with underlying biological behavior.
To study a primary tumor, researchers focus on its cellular composition, growth patterns, and interactions with surrounding tissue. These observations connect the structure and behavior of the tumor to local expansion and possible spread. The same biological assessment can contribute to research on cancer initiation, progression, diagnosis, prognosis, and treatment response.
Even after distant secondary tumors are identified, the original site remains biologically informative. It records where the cancer began and provides a basis for relating local growth, tissue invasion, and release of cells into vessels to later disease spread. This connection helps researchers interpret progression as a sequence rather than as unrelated tumor locations.
In biology, primary-tumor research connects molecular regulation with cell behavior, tissue organization, and disease progression. Researchers can relate genetic and epigenetic disruption to altered division and survival, then examine how those cells interact with surrounding tissue and spread. This multilevel view helps explain cancer initiation, progression, and treatment response as connected biological processes.
