2023
In this video, we develop a proximal co-culture model of ovarian cancer cells and primary human mesothelial cells. This physiologically relevant model allows the study of paracrine signaling, where the localized concentrations of the secreted factors are maintained while preventing direct cellular contact.

This video demonstrates a method to differentiate human neural progenitor cells (NPCs) into neurons. The NPCs are introduced onto an established mouse astrocyte-rat cortical neuron co-culture, promoting NPC differentiation into neurons. The differentiation is confirmed by visualizing the cells under a confocal microscope.

2025
The video demonstrates a method for culturing neurons from murine hippocampi. Initially, the hippocampi undergo enzymatic digestion to break down the extracellular tissue matrix. Subsequently, the digested tissue is mechanically disrupted to isolate individual neurons. Finally, these neurons are cultured on glial feeder cells.
FAQs
Culture medium does more than supply nutrients: it provides the chemical environment that supports cell viability, while temperature, pH, and gas exchange influence cellular maintenance. Keeping these variables suitable and consistent helps cells retain expected structure, function, and behavior. In comparative experiments, standardized conditions make observed differences more likely to reflect the tested factor rather than culture variation.
Confluence indicates that adherent cells have occupied the available growth surface, so continued maintenance requires passaging. Detachment allows the cells to be redistributed under new culture conditions, supporting continued growth and study. Performing this step at an appropriate stage helps preserve viability and relevant biological characteristics for subsequent experiments.
Aseptic handling helps preserve sterility during routine culture manipulation. This protection supports cell viability and reduces avoidable variation between cultures, which is essential when researchers compare treatments or observations. Together with consistent temperature, pH, gas exchange, and medium conditions, sterile practice improves reproducibility and strengthens confidence in biological results.
Cultured cells provide a controlled setting in which researchers can observe cellular structure, function, and behavior directly while experimentally manipulating conditions. This combination is valuable in biology because it links controlled interventions with measurable cellular responses. The approach therefore supports focused investigations in molecular biology and developmental biology without relying only on observations made within an organism.
A typical workflow begins by placing cells in nutrient-rich culture medium and maintaining them under suitable temperature, pH, gas-exchange, and sterile conditions. Researchers then monitor the culture, particularly when cells grow attached to a surface. Once adherent cells reach confluence, they are detached and passaged to continue maintenance under controlled conditions.
The method supports molecular and developmental biology, disease modeling, drug testing, and biotechnology. Its value comes from allowing living cells to be observed and manipulated under reproducible conditions, so researchers can examine cellular responses relevant to disease or treatment. Maintaining viability and biologically relevant characteristics is important when interpreting results across these applications.
