The video showcased a cell culture method for differentiating neural progenitor cells into neurons. By incubating cells in a nutrient-rich medium supplemented with growth factors, the progenitor cells matured into neurons with developed axons and dendrites. A stabilizing agent ensured cell viability and protected against oxidative damage throughout the differentiation process.
