Differentiation of Mouse Embryonic Stem Cells into Spinal Motor Neurons

Mouse embryonic stem cells (meSCs) expressing the green fluorescent protein (GFP) under the MN-specific promoter HB9 (HBG3 cells) were a kind gift from Tom Jessell (Columbia University, New York, NY, USA). Their differentiation into MNs was performed as described [19 (link),51 (link)]. Briefly, meSCs cells were cultured on a monolayer of EmbryoMax® Primary Mouse Embryonic Fibroblasts (Millipore, Billerica, MA, USA). For differentiation into MNs, cells were lifted with trypsin and resuspended (around 1–2 × 106 meSCs per 10 cm2 dish) in culture medium consisting of knockout DMEM/F12, 10% knockout serum replacement, 1% N2, 0.5% L-glutamine, 0.5% glucose (30% in water), and 0.0016% 2-mercaptoethanol) on nonadherent Petri dishes to enable the formation of embryoid bodies (EBs). After one day of recovery, 2 μM retinoic acid (Sigma-Aldrich, St. Louis, MO, USA) and 2 μM smoothened agonist (SAG, a Shh agonist) were added freshly every day with the new medium. After 5 days of differentiation, EBs were dissociated and sorted based on levels of GFP using a FACSVantage/DiVa sorter (BD Biosciences, Rockville, MD, USA). Representative bright field images of meSCs and EBs, as well as immunocytochemical staining for ChAT and Smi-32 MN markers, are depicted in Supplementary Figure S2C.

Differentiation of Motor Neurons from Stem Cells

Mouse ESCs or iPSCs expressing Hb9∷GFP reporter were cultured on top of inactivated mouse fibroblasts (Millipore). Motor neuron differentiation was induced by plating 1-2 × 106 mES cells per 10 cm dish in the presence of 2 μM retinoic acid (Sigma-Aldrich) and 2 μM purmorphamine (Calbiochem, Billerica, MA). After 5 days of differentiation, embryonic bodies were dissociated and sorted based on levels of GFP using a FACSVantage/DiVa sorter (BD Biosciences, Rockville, MD).

Myh6 Promoter-Driven Cell Sorting

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were dissociated to single cell suspensions and analyzed on a FACSCanto or LSRFortessa (BD Biosciences) for eGFP under control of the Myh6 promoter. For extracellular staining, cells were incubated for 30 minutes with antibodies as listed in the supplement. Prior to analysis, cells were incubated with propidium iodide (PI) to label non-viable cells. Data analysis was performed using FlowJo (Treestar). Measured events were gated for PI negative populations (exclusion of dead cells) and/or forward/side scatter (exclusion of debris and aggregates) before producing histograms or dot plots. Samples for sorting where processed similarly and were run on a FACS Vantage-Diva sorter (BD Biosciences).

Mouse ESCs or iPSCs expressing Hb9::GFP reporter were cultured on top of inactivated mouse fibroblasts (Millipore). MN differentiation was induced by plating 1-2 × 106 cells per 10 cm dish in the presence of 2 μM retinoic acid (Sigma-Aldrich) and 2 μM purmorphamine (Calbiochem, Billerica, MA). After 5 days of differentiation, embryonic bodies were dissociated and sorted based on levels of GFP using a FACSVantage/DiVa sorter (BD Biosciences, Rockville, MD).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
