Why Use Pre-optimized Reagents to Differentiate Pluripotent Stem Cells into Dopaminergic Neurons?
The loss of dopaminergic neurons in the substantia nigra is a characteristic of Parkinson’s disease (PD), a neurodegenerative disorder that affects motor function.
Both animal models and clinical trials have suggested that cell replacement therapies may be effective in treating PD. However, this approach is limited by the availability of a rich, effective source of neural precursors for dopaminergic neuron generation. While embryonic and induced pluripotent stem cells can be differentiated into dopaminergic neurons, successful differentiation is dependent on high quality media and defined differentiation supplements. R&D Systems offers the Human/Mouse Dopaminergic Neuron Differentiation Kit to drive successful and efficient differentiation of embryonic and induced pluripotent stem cells into dopaminergic neurons.
R&D Systems Human/Mouse Dopaminergic Neuron Differentiation Kit:
- Includes high quality reagents to generate dopaminergic neurons in 27 days.
- Includes pre-optimized components with low lot-to-lot variation.
- Includes sufficient reagents for differentiation of 3 x 107 pluripotent stem cells.
The Human/Mouse Dopaminergic Neuron Differentiation Kit contains ITS and N-2 MAX Media Supplements, which are used to select and enrich neural stem cell populations. Bovine Fibronectin is included to support cell attachment and spreading. A growth factor panel, consisting of Recombinant Human Fibroblast Growth Factor Basic (FGF basic), Recombinant Mouse Fibroblast Growth Factor 8b (FGF-8b) and Recombinant Mouse Sonic Hedgehog Amino-terminal Peptide (Shh-N), is included for effective dopaminergic differentiation.
The quantity of each component provided in the kit is estimated to be sufficient for differentiation of 3 x 107 embryonic stem cells.

Characterization of Dopaminergic Neurons Generated from Human Pluripotent Stem Cells. Dopaminergic neurons were generated from human pluripotent stem cells using the Dopaminergic Neuron Differentiation Kit (Catalog # SC001B). Tyrosine Hydroxylase was detected using a Mouse Anti-Human Tyrosine Hydroxylase Monoclonal Antibody (Catalog # MAB7566). The cells were stained with the NorthernLights™(NL) 557-conjugated Donkey Anti-Mouse Antigen Affinity-purified Secondary Antibody (Catalog # NL007, red). Neuron-specific beta-III Tubulin was detected using a Mouse Anti-Neuron-specific beta-III Tubulin (Clone Tuj-1) Monoclonal Antibody (Catalog # MAB1195) followed by the NL493-flourochrome-conjugated Donkey Anti-Mouse Antigen Affinity-purified Secondary Antibody (Catalog # NL009, green).

Assay Procedure
Refer to the product datasheet for complete product details.
Briefly, pluripotent stem cells are differentiated into dopaminergic neurons using the following procedure:
- Generate embryoid bodies from pluripotent cells
- Select for and expand Nestin positive cells
- Differentiate Nestin positive cells into dopaminergic neurons

Protocol for the Differentiation of Pluripotent Cells into Dopaminergic Neurons using the Human/Mouse Dopaminergic Neuron Differentiation Kit (Catalog # SC001B)
Selection of Nestin-positive Cells
Generate embryoid bodies (EB) from pluripotent stem cells.
Transfer EB to a 10 cm culture dish containing KO-ES Media.
Culture the cells for 24 h at 37 °C and 5% CO2.
Replace the KO-ES Media with ITS/Fibronectin Media.
Culture the cells for 6-8 days at 37 °C and 5% CO2.
Replace the media every 2 days.
Verify successful differentiation by staining cells for Nestin.
Expansion of Nestin-Positive Cells
Wash the cells twice with sterile PBS.
Dissociate the cells with 0.05% Trypsin/EDTA.
Add 5 mL of KO-ES Media to neutralize the Trypsin
Transfer the cells to a 15 mL tube.
Remove the cell clumps by allowing the tube to stand for approximately 5 minutes and then transferring the suspended cells to a 15 mL tube.
Centrifuge the samples at 220 x g for 5 minutes.
Resuspend the cell pellet in N-2 MAX/FGF basic/FGF-8b/Shh-N/Ascorbic Acid Media.
Perform a cell count.
Plate the cells on Poly-L-ornithine/Fibronectin-coated plates at 3-5 x 105 cells/well in 500 μl of media.
Replace the media daily for 4-6 days with N-2 MAX/FGF basic/FGF-8b/Shh-N/Ascorbic Acid Media.
Differentiation of Nestin-positive Cells to Dopaminergic Neurons
Culture the cells in N-2 MAX/Ascorbic Acid Media without growth factors for 10-15 days.
Replace the media every 2 days.
After 10-15 days, dopaminergic neurons can be identified by staining for expression of Tyrosine Hydroxylase and Neuron-specific beta-III Tubulin.

FAQs
-
Can the Human/Mouse Dopaminergic Neuron Differentiation Kit work with a starting population of neural progenitor cells instead of mouse pluripotent stem cells?
The kit may work with a starting population of neural progenitor cells, but we have not tested this. If starting with neural progenitor cells we recommend starting at Stage 5 of the Dopaminergic Neuron Differentiation Kit protocol. The starting cell density would also have to be optimized.
