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.

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...

Arginine-vasopressin (AVP) controls fine-tuning of body water homeostasis through facilitating water reabsorption by renal principal cells. Here, we present a protocol for the cultivation of primary rat inner medullary collecting duct cells suitable for the elucidation of molecular mechanisms underlying AVP-mediated water reabsorption.
FAQs
Maintaining viability requires sterile handling, suitable nutrients, controlled temperature, appropriate gas exchange, and, for cells that need adherence, a compatible substrate. These variables determine whether isolated cells remain functional and continue growing after tissue dissociation. Consistent control is especially important because primary cells have limited lifespans and may respond sensitively to changes in their culture environment.
Primary cells can retain characteristics associated with their tissue and donor, so results may reflect biologically meaningful variation rather than a uniform response. Passage history also matters because these cultures generally have limited lifespans and variable growth. Recording the source and passage status helps researchers judge whether observed differences arise from the experimental treatment or from the cells themselves.
Primary cells more closely preserve features of normal biology, whereas immortalized lines are commonly selected for sustained growth. Their limited lifespan and variable expansion can make experiments less uniform, but those same properties may improve biological relevance. The choice therefore depends on whether a study prioritizes a closer tissue-like model or a consistently growing system for repeated experiments.
Some isolated cells require attachment to a substrate for continued maintenance, while others may not depend on that condition. Providing an appropriate attachment surface is therefore part of matching the culture environment to the cells being studied. When attachment is needed, inadequate substrate support can limit the ability of the recovered cells to remain viable or grow during the experiment.
A typical workflow begins with obtaining a tissue sample, followed by mechanical or enzymatic dissociation to release individual cells. The recovered cells are then placed under sterile, controlled conditions with suitable nutrients, temperature, gas exchange, and, when required, an attachment substrate. Researchers subsequently monitor the culture while accounting for its source, growth variability, and passage history.
Primary cells are useful when experimental relevance to normal biology, donor-specific characteristics, or tissue-derived responses is important. They can support studies of cell function, development, disease mechanisms, drug responses, and toxicity. An immortalized line may be preferable when sustained growth and greater consistency are more important than retaining the limited lifespan and biological features associated with freshly isolated cells.
These cultures can provide a model for examining how cells function, develop, or respond to disease-associated conditions. They also support evaluation of drug responses and toxicity under controlled laboratory conditions. Because the cells originate from tissue and may retain donor-specific characteristics, their responses can add biological context that is valuable when interpreting normal or disease-related cellular behavior.
