Can the Human/Mouse Dopaminergic Neuron Differentiation Kit work with a starting population of neural progenitor cells instead of mouse pluripotent stem cells?

Name: Human/Mouse Dopaminergic Neuron Differentiation Kit
Brand: R&D Systems
SKU: SC001B

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.

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.

Kit Components

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.

Neural stem cells provide an excellent model for research focused on neural development and neurological disorders. R&D Systems offers ready-to-use primary cortical stem cells isolated from E14.5 Sprague-Dawley rats. In addition, primary mouse cortical stem cells isolated from E14.5 CD-1 mice are available. Every lot of R&D Systems Cortical Stem Cells is validated for a high level of Nestin expression and the capacity for multi-lineage differentiation into astrocytes, neurons, and oligodendrocytes. Our cortical stem cells are tested to ensure highest quality and lot to lot consistency. Both rat and mouse Cortical Stem Cells can be optimally expanded as monolayers or neurospheres.

To complement the use of primary neural stem cells, we offer a range of supportive products, including culture media which is specifically optimized for use with neural stem cells. We offer kits to promote the in vitro proliferation of neural precursors, and kits to differentiate neural stem cells into dopaminergic neurons or oligodendrocytes. In addition, kits are available which contain panels of antibodies designed to monitor the differentiation and identification of neural precursors, astrocytes, neurons, and oligodendrocytes.

Scientific Data Examples for Human/Mouse Dopaminergic Neuron Differentiation Kit

	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).

Procedure Overview

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.

Plate the cells on Poly-L-ornithine/Fibronectin-coated plates at 3-5 x 105 cells/well in 500 µl of 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.
