At 48 h post-fixation, hearts were sectioned into 200-µm slices. For staining, slices were first incubated for 10 min in blocking solution (3% normal donkey serum (NDS) in PBST), followed by primary antibody staining overnight at 4 °C using the following antibodies: anti-vimentin (ab24525), anti-cardiac troponin I (ab188877) or anti-PGP9.5 (ab108986), purchased from Abcam at 1:200 dilution in blocking solution. Slices were then washed twice in PBST, then stained with secondary antibodies (1 mg ml−1) at 1:500 dilution for 3 h at room temperature using the following: F(ab’)2 anti-chicken 488 (703-546-155) and anti-rabbit 647 (711-606-152) purchased from Jackson ImmunoResearch Laboratories. The slices were then stained with DAPI and washed three times with PBST (30 min per wash). Sections were mounted onto slides and mounted with exPROTOS. Slices were imaged on a confocal microscope (Olympus FV3000).

Briefly, cardiac sections were deparrafinized and rehydrated, and antigens were retrieved using Retreivit 6 (InnoGennex). Sections were treated with 2% Sudan Black (Sigma-Aldrich) in 70% ethanol to quench autofluorescence and blocked with 3% BSA (Sigma-Aldrich). Slides were incubated with primary antibodies against TGF-β 1/2/3 (sc-7892, Santa Cruz Biotechnology), TGF-β (ab66043, Abcam), Troponin I (ab188877, Abcam), Integrin β3 (ab75872, Abcam), and Laminin (ab11575, Abcam) in PBS with 1% BSA. AlexaFluor-labeled secondary antibodies with ‒488 or ‒555 conjugates were used (Thermo Fisher Scientific). Images were obtained from 5 fields of 4 separate hearts for each staining condition.

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.
