Immortalized Human Dopaminergic Neuronal Precursor Cells (LUHMES)

T02841x106 cells / 1.0 ml



The Immortalized Human Dopaminergic Neuronal Precursor Cells, also known as the Lund Human Mesencephalic (LUHMES) cell line, is a subclone of the tetracycline-controlled, v-myc-overexpressing human mesencephalic-derived cell line MESC2.10. This cell line is unique in that it can be differentiated to acquire a dopaminergic neuron-like phenotype under appropriate growth conditions. LUHMES expresses functional dopamine transporter (DAT), vesicular monoamine transporter (VMAT-2), tyrosine hydroxylase (TH) and the neuronal form of β-III tubulin after differentiation. In addition to retaining dopaminergic neuronal-specific markers, LUHMES also exhibit electrophysiological properties, thus making this cell line a valuable neuronal model for neurodevelopmental studies, disease modelling and neuropharmacology.

Propagation Requirements

Grow the cells in culture vessel pre-coated with 50 μg/ml poly-L-ornithine (PLO) (TM062) and 1 μg/ml fibronectin (EMD Millipore; Cat. FC010) in H2O for at least 3 hours at 37°C. Do not grow these cells in culture vessels with surface areas equal to less than 12.5 cm2. These cells do not grow in 6-well, 24-well, 48-well, or 96-well plates.

The base medium for this cell line is Advanced DMEM/F12 (Gibco;12634010). To make the complete growth medium, add the following components to the base medium: N2 supplement (ThermoFisher Scientific) to a final concentration of 1X, L-glutamine (G275) to a final concentration of 2 mM, and Recombinant Human FGF2 (Z101455) to a final concentration of 40 ng/ml.
Change media every 2-3 days. Do not let media colour change to orange-yellow.
The cells will form round clumps instead of a monolayer when stressed. It is recommended to subculture when cells are grown to a cell density of 50-60%.
Carbon dioxide (CO2): 5%, Temperature: 37.0°C.
To subculture the cells, use 0.25% Trypsin-EDTA (TM051). After adding trypsin, incubate the cells at room temperature for 2-3 minutes and agitate the culture vessel until 90% of the cells have detached. Immediately neutralize the trypsin using Trypsin Neutralizing Solution (Lonza, Cat. CC-5002). Add Trypsin Neutralizing Solution twice the volume of trypsin used. Centrifuge at 200x g for 2-3 minutes. Aspirate supernatant and resuspend cells in complete media. Plate cells into pre-warmed PLO-fibronectin-coated vessels at 37.0°C. Avoid subculturing if the cells appear stressed. Note: If leaving the cells over the weekend (or more than 2 days), make sure to do a high split ratio (1:4 to 1:5).

To differentiate the cells into neurons, change the medium to differentiation medium after the cells have grown to a density of 40-50%.
To make complete differentiation medium, add the following components to Advanced DMEM/F12 (Gibco;12634010): N2 supplement to a final concentration of 1X, L-glutamine (G275) to a final concentration of 2 mM, dbcAMP to a final concentration of 1 mM, tetracycline to a final concentration of 1 μg/ml, and Recombinant Human GDNF (Z101055) to a final concentration of 2 ng/ml. Allow the cells to grow in differentiation medium for 4-6 days before testing for neuron specific markers.


mRNA and protein expression levels of various markers pre and post differentiation are verified by RT-PCR and western blotting.

I want to make sure these cells express my gene of interest before I decide to buy the cell line. Can you provide a sample so this can be tested?
We do not carry out downstream characterization or gene expression profiling of our cell lines. To facilitate your preliminary experiments we can provide an RNA extraction (0.5ug total RNA) or cell lysate (100ug/100ul provided in 62.5mM Tris‐HCl, 2% SDS, 10% Glycerol, 50mM DTT, 0.01% w/v Bromophenol Blue) for any of our immortalized cell lines for a small fee. Please inquire directly for more information. The lead time will be around 2 weeks from the time of placing an order (if the item is in stock).
How often do I need to change the media?
The media should be changed every 2-3 days.
Why do these cells need bio safety level II?
In order to be more cautious, we follow the CDC-NIH recommendations that all mammalian sourced products should be handled at the Biological Safety Level 2 to minimize exposure of potentially infectious products. This information can be found in 'Biosafety in Microbiological and Biomedical Laboratories' (1999). Your institution's Safety Officer or Technical Services will be able to make the call as to whether BioSafety Level I is possible with these cells at your site if required.
Do you sell ECM coated T75 flasks?
Yes we can provide a coating service. Please inquire with [email protected]
What can I coat a larger dish to subculture?
We also offer applied extracellular matrix (collagen type I) in liquid form, for the coating of larger flasks and other required plasticware:
How long can I store frozen vials for?
Cells that are properly frozen using an effective cryoprotective agent can be stored in liquid nitrogen indefinitely without affecting their recovery.
Should the cap of the flask be changed before starting the cell culturing step?
No, there is no need in sterile biosafety cabinets unless it has contacted any non-sterile condition (e.g. touching the contaminated tip, etc.).
What is the recommended storage temperature?
In general, if you received: Live cells: acclimatize for 3-4 hrs at at the recommended conditions stated for the cell line under the propagation section, and then change media afterwards. Frozen cells: Immediately place cells in liquid nitrogen; -180C.
How is cell density crucial for drug selection?
If antibiotic selection is applicable to the target cells, we suggest getting rid of all the background cells so that the cell density is kept lower (even 20-30%). However, once the clones are selected by clonal dilution, we don't need the drug to still be present. If needed, the cell density should be towards the higher end since cells are already selected. Any primary cells still present will be depleted as a result of senescence and the cell population that remains will be resistant to the specific antibiotic.
My cells are not detaching, what method do you recommend to trypsinize the cells?
1. Incubate the coated plate containing trypsin solution at recommended temperature indicated in the propagation section for 3-5 min till the cells round up, monitoring from time to time under microscope. 2. Diluting G422 (1:1) with PBS and coating for lesser time. Sometimes the collagen content in G422 is higher and thus make stronger bonding with cells. 3. You can try reducing the incubation time as well for coating the plate to make a thinner layer.
Why is it important to determine the optimal seeding density?
The seeding density we recommend is for when cells are plated to a new vessel. The optimal seeding density should allow cells to attach to the surface and have room to proliferate. If you seed too little, cells may not attach well to the surface (for adherent cells). Seeding density is important as many cells (adherent or suspension cells) need to be in close proximity for better growth. Cell-cell interactions allow cells to communicate with each other in response to changes in their microenvironment. This ability to send and receive signals is essential for the survival of the cell. In other cases, if the seeding density is too low, cells may attach but a retardation in cell growth is observed. If you seed too high, the cells will attach but there is insufficient room for further proliferation and they will stop replicating.
