Mouse embryos and neonates were collected, fixed in 4% PFA, embedded in OCT, and frozen in dry iced hexane. Frozen sections were blocked with 5% goat serum, stained with mouse anti-TNNT2 (Thermo Scientific), mouse anti-sarcomeric alpha-actinin (Sigma Aldrich), rabbit anti-TNNI3 (Santa Cruz), rabbit anti-TGFβ1 (Abcam), rabbit anti-Ki67 (Thermo Scientific), rabbit anti-phospho-Histone H3 (Cell Signaling Technology), and Hoechst 33342, and visualized using Alexa Fluor-conjugated secondary antibodies (Life Technologies). Image acquisition was performed on a Zeiss LSM510 Meta inverted confocal microscope (Carl Zeiss) or an Eclipse 80i fluorescent microscope (Nikon). Transgenes were detected by PCR from yolk sac DNA of embryos or tail DNA of neonatal pups. For human heart tissues, formalin-fixed paraffin embedded tissue-sections were rehydrated and autoclaved with Citrate Buffer, pH 6.0 (Sigma-Aldrich) and stained with rabbit anti-phospho-Smad2 (EMD Millipore), rabbit anti-PRDM16 (Abcam), mouse anti-sarcomeric alpha-actinin (Sigma Aldrich) and Hoechst 33342, and visualized using Alexa Fluor-conjugated secondary antibodies (Life Technologies). Image acquisition was performed on an Eclipse 80i fluorescent microscope (Nikon). A detailed list of antibodies used is shown in Supplementary Table 10.

NRCs were transiently transfected with GFP-tagged C3C6 constructs using Escort III (Sigma) as described previously (31 (link)) and then fixed and permeabilized as aforementioned. Immunostaining was carried out using primary antibodies against mouse antisarcomeric alpha-actinin (Sigma) and rabbit anti MyBP-C (a generous gift from Prof Mathias Gautel, Kings College London) and secondary antibody/counterstain solution (Cy3-goat anti-mouse, catalog no.: 115-165-146; Jackson Immunochemicals) and Atto 647N-goat anti-rabbit (Sigma). Cells were mounted using 70% glycerol/PBS according to the antibody manufacturer instructions. Samples were imaged using a STEDYCON (Abberior) attached to a Leica TCS SP5 confocal microscope equipped with 594 nm and 640 nm excitation lasers and a 775 nm depletion laser using a 100×/numerical aperture 1.4 oil immersion lens. Images were recorded at a pixel size of 20 nm.

Cells grown on cover slips were fixed using 4% PFA, permeabilized with 0.5% Triton X-100, incubated with primary antibodies and Hoechst 33342, and detected using Alexa Fluor conjugated secondary antibodies. Primary antibodies used include mouse anti-FLAG M2 (Sigma Aldrich), rabbit anti-cardiac troponin T (Abcam), mouse anti-cardiac troponin T (Thermo Scientific), mouse anti-sarcomeric alpha-actinin (Sigma Aldrich), or rabbit anti-TBX20 (Abcam), as published previously45 (link). Image acquisition was performed on an Eclipse 80i fluorescent microscope and a confocal microscope (Carl Zeiss, LSM 510 Meta) and ZEN software (Carl Zeiss). Measurement of cell surface area and length was performed using NIS-Elements Basic Research 3.0 software (Nikon). A detailed list for antibodies used is shown in Supplementary Table 10.

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.
