LHCN-M2 immortalized human satellite cells,
72 (
link) carrying 2 (CTG·CAG)5 alleles (5/5 in short), were grown on 0.1% (w/v) gelatin-coated plastic surfaces in
skeletal muscle cell basal medium (PromoCell) with Supplement Mix (0.05 mL/mL fetal calf serum, 50 µg/mL fetuin (bovine), 10 ng/mL epidermal growth factor (recombinant human), 1 ng/mL basic fibroblast growth factor (recombinant human), 10 µg/mL insulin (recombinant human), 0.4 µg/mL dexamethasone), supplemented with 1% (v/v)
GlutaMAX and 15% (v/v)
bovine growth serum (Thermo Scientific) at 7.5% CO
2 and 37°C.
Primary DM1 myoblasts (13/800),
73 (
link) were grown on 0.1% (w/v) gelatin-coated plastic surfaces in
Ham's F10 medium (Gibco) supplemented with
GlutaMAX and 20% (v/v)
bovine growth serum (Thermo Scientific) at 7.5% CO
2 and 37°C.
Immortalized DM500 mouse myoblasts expressing a human DM1 genomic fragment carrying a (CTG·CAG)n repeat of approximately 500 triplets
74 (

fetal bovine serum (PAA, Pasching, Austria), 4 mM
L-glutamine (Gibco), 1 mM
pyruvate (Sigma), 50 µg/mL
gentamicin (Gibco), 20 units/mL γ-interferon (BD Biosciences) and 2% (v/v) chicken embryo extract (Sera Laboratories International) at 7.5% CO
2 and 33°C.
