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.

Vestibular Schwannomas (VSs) are non-malignant tumors of Schwann cell (SC) origin, associated with mutations in the NF2 tumor suppressor gene. We report a reproducible, efficient protocol for primary human VS cell culture that allows for molecular and cellular experimental manipulation and analysis and recapitulates the heterogeneous nature of human disease.

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.

Primary Neuronal Cultures

The complexity of the brain often requires neuroscientists to use a simpler system for experimental manipulations and observations. One powerful approach is to generate a primary culture by dissecting nervous system tissue, dissociating it into single cells, and growing those cells in vitro. Primary cultures make neurons and glia easily accessible to the experimental tools required for techniques like genetic manipulation and time-lapse imaging. Furthermore, these cultures represent a highly...
FAQs
Primary Tumor Culture can preserve tumor characteristics because it begins with freshly isolated patient material rather than cells adapted through long-term line maintenance. That distinction may retain features relevant to tumor heterogeneity and cell-cell relationships. Consequently, observations can reflect aspects of the original tumor that might be reduced or absent in established cell-line systems.
Within the culture, malignant, stromal, and immune populations can contribute different biological perspectives. Their coexistence helps researchers examine not only cancer cells themselves but also interactions among cell types that may influence tumor behavior. Preserving these relationships is especially relevant when studying heterogeneity, because different populations can be represented together rather than evaluated only as an isolated malignant-cell population.
Attachment and three-dimensional organization provide alternative ways to maintain cultured cells and study their behavior. Supporting attachment can help sustain cells on a growth surface, whereas three-dimensional organization can preserve a tissue-like arrangement. Selecting or comparing these formats may therefore affect how researchers examine survival, proliferation, and interactions within the model.
Work generally begins with tumor tissue that is dissociated into viable cells. The cells are then placed in defined growth conditions designed to support their maintenance, with attachment or three-dimensional organization used as appropriate. Researchers monitor whether the cells survive and proliferate, using those observations to judge whether the culture is providing a useful experimental model.
These cultures support direct investigation of tumor biology, treatment response, and drug resistance. Because the model can retain heterogeneous cell populations and their interactions, researchers may examine how the cultured material behaves under experimental treatment conditions. The resulting observations help connect cellular behavior with features of the patient-derived sample, while recognizing that the culture remains a laboratory model.
They provide a patient-derived experimental system that can complement animal studies rather than replace them. This is useful when researchers want to examine tumor behavior or treatment response in cells originating from a particular patient. Such models may also contribute to more individualized approaches to cancer therapy by preserving clinically relevant features that inform investigation of therapeutic sensitivity or resistance.
