Differentiation of Neural Progenitor Cells into Neurons

Abstract
Source: Mao, X., et al. Neuronal Differentiation from Mouse Embryonic Stem Cells In vitro. J. Vis. Exp. (2020).
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.
Protocol
1. Differentiation from NPCs to neurons (Phase II)
- Seed about 5 x 105 mouse embryonic stem cells or mESC derivatives within 2 mL of basal differentiation medium I per well onto the 0.1% gelatin-coated 6-well plates. Randomly divide the mESC derivatives into 3 groups, as Phase II protocol 1, protocol 2, and protocol 3, respectively.
- Place the plate into the 5% CO2 incubator at 37 °C to allow for attachment for 6 h. Wash them twice with 2 mL of PBS.
- Add 2 mL of basal differentiation medium I, N2B27 medium I and N2B27 medium II (Table 1), respectively, to each well of the above groups.
- Place the plates into the incubator and allow them to differentiate for another 10 days. Change the corresponding medium every 2 days.
- Check the differentiation status and record the morphological changes as mentioned in step 3.
- On Day 18, evaluate the generation of neurons (β-Tubulin III positive) and determine the differentiation efficiency of the 3 protocols used in step 4.
