C2C12 myoblasts (American Type Culture Collection, USA) were cultured in DMEM supplemented with 10% FBS and 1% P/S. The C2C12 myoblasts were trypsinized using 0.25% trypsin/0.1% EDTA when they reached 70–80% confluence. The cells were maintained in a cell culture incubator (Sanyo, Japan) with 5% CO2 at 37°C.

Check if the same lab product or an alternative is used in the 5 most similar protocols
3T3-L1 adipocytes were purchased from the Cell Resource Center of Shanghai Academy of Life Sciences, Chinese Academy of Sciences, while C2-C12 myoblasts and HEPA1-6 hepatoma cells were purchased from ATCC cell bank. 3T3-L1 adipocytes, C2-C12 myoblasts, and HEPA1-6 hepatoma cells were cultured in a DMEM medium containing 10%FBS in an incubator at 37°C and 5% CO2. When the cells grew to the logarithmic phase and the density was 80%, they could be used in the experiment. The above three kinds of cells were transferred to a six-well plate and cultured to about 60% of the cell density, and the lentivirus prepared in advance for knocking out sidt2 and having puro resistance was added to the culture medium. In order to make the lentivirus better-transfected cells, the cells were not treated within 48 hours, and the culture medium could be replaced after 48 hours. 72 hours after the virus was added, the new medium was replaced, and an appropriate amount of puro was added to it to screen cells (the amount of puros varied according to different cell lines). At the same time, it was necessary to add polybrene, to increase the transfection efficiency of the virus. The cells were screened by adding puro for three consecutive days, and the screened cells were cultured normally.

Immortalized Brown and White Adipogenesis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Primary brown preadipocytes were isolated from BAT of newborn WT, LSL-K36M;Cre-ER or A-K36M mice. Cells were immortalized by infecting with retroviruses expressing SV40T13 (link). 3T3-L1 cells were from Daniel Lane. Adipogenesis of immortalized brown preadipocytes and the 3T3-L1 white preadipocyte cell line were induced by adding induction medium (Dulbecco's modified Eagle's medium (DMEM) supplemented with 10% fetal bovine serum (FBS), 0.02 μM insulin, 1 nM T3, 0.5 mM isobutylmethylxanthine, 2 μg ml−1 dexamethasone, and 0.125 mM indomethacin)12 (link). After 2 days of induction, the culture medium was changed to DMEM supplemented with FBS, insulin, and T3 only. PPARγ-stimulated or C/EBPα-stimulated adipogenesis was done by infecting cells with retroviruses expressing PPARγ or C/EBPα before induction33 (link).
C2C12 myoblasts were purchased from ATCC and cultured in growth medium (DMEM supplemented with 15% FBS). Myogenesis was induced by changing growth medium to differentiation medium (DMEM supplemented with 2% horse serum) when cells were confluent8 (link).

C2C12 Myoblast Differentiation Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
C2C12 myoblasts were purchased from ATCC (Manassas, VA, USA). Myoblasts were grown to confluence in normal growth media (DMEM plus 10% FBS, 100 U/mL penicillin, 100 U/mL streptomycin) at 37 °C in a water-saturated atmosphere of 5% CO2. To promote differentiation of mono-nucleated myoblasts into multinucleated myotubes the media was switched to differentiation media (DMEM plus 2% HS, 100 U/mL penicillin, 100 U/mL streptomycin). Fully differentiated myotubes were normally present upon 5–6 days incubation in differentiation media.

Differentiation of C2C12 Myoblasts to Myotubes

Check if the same lab product or an alternative is used in the 5 most similar protocols
C2C12 myoblasts (2 × 103 cm2, passage number 6; ATCC, Manassas, VA, USA) were cultured in 25 cm2 culture flasks with Dulbecco’s modified Eagle’s medium (DMEM; HyClone, Oud-Beijerland, Holland) supplemented with Glutamax-I (4 mM L-alanyl-L-glutamine), 4.5 g/L glucose (Invitrogen, Carlsbad, CA, USA), and 10% heat-inactivated fetal bovine serum (FBS; Hy-Clone, Oud-Beijerland, Holland). The cells were incubated at 37 °C with 5% CO2 in a humidified atmosphere. Cells were split 1:6 twice weekly and fed 24 h before each experiment. Differentiation into myotubes was achieved via culturing pre-confluent cells (85% confluency) in a medium containing 2% FBS, and they were monitored via microscopy, and for myogenin and MHC expression, via Western blot analysis [74 (link),75 (link)].

C2C12 Myoblast Differentiation Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
C2C12 myoblasts (ATCC, Manassas, VA, USA), a mouse myogenic progenitor cell line, were grown in a growth medium (GM; 10% fetal bovine serum (FBS)-containing Dulbecco’s modified Eagle’s medium (DMEM) supplemented with antibiotics (penicillin-streptomycin, 1%, Gibco, Carlsbad, CA, USA) at 37 °C in a 5% CO2 humidified condition. The myoblasts were then cultured on 35 mm plates at a density of 1.3 × 105 in 2 mL of GM. When confluency reached 80 to 90%, a differentiation medium (DM) composed of horse serum (2%, dialyzed, Gibco) in DMEM supplemented with 1% penicillin-streptomycin was used to induce cell differentiation. The medium was refreshed every 24 h. When necessary, cells were pretreated with either bovine serum albumin (BSA) or BSA-conjugated PA (100 μM) in GM for 24 h before differentiation. All reagents and materials were obtained from Sigma-Aldrich unless otherwise specified.

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.
