RNA was extracted using the RNeasy RNA Micro Kit (Qiagen) per the manufacturer's instructions and quantified using Qubit (ThermoFisher Scientific). One microgram of RNA was then reverse transcribed using SuperScript™ IV Reverse Transcriptase (ThermoFisher, 18090200), dNTP (ThermoFisher, 18427013), RNaseOUT™ Recombinant Ribonuclease Inhibitor (ThermoFisher, 10777019), Oligo(dT)20 Primer (ThermoFisher, 18418020). Quantitative PCR was performed using Kapa SYBR Fast Master mix (Sigma-Aldrich, KK4622) and the primers used were hCSF2RB fwd: 5′ AACGGGATCTGGAGCGAGTG 3′, hCSF2RB rev: 5′ AGATCACGATGAGGGCCAGC 3′, hGAPDH fwd: CTTTTGCGTCGCCAGCCGAG, hGAPDH rev: CCAGGCGCCCAATACGACCA. Each mRNA level was measured as a fluorescent signal normalized based on the signal for β-actin. Relative quantification was determined by the ΔΔCt method and normalized according to β-actin.

RNA was extracted from the cardiac slices or cultured cells using
the RNeasy RNA micro kit (Qiagen). RNA concentration was measured using a
nanodrop spectrophotometer (ThermoFisher Scientific). For cardiac slices,
cDNA synthesis was performed using the High Capacity RNA to cDNA synthesis
kit (Applied Biosystems). For cultured macrophages, cDNA was synthesized
using the iScript™ Reverse Transcription Supermix (Bio-Rad) and
pre-amplified using the Sso Advanced PreAmp Supermix kit (Bio-Rad).
Quantitative real time PCR reactions were prepared with sequence-specific
primers (IDT) with PowerUP™ Syber Green Master mix (ThermoFisher
Scientific) in a 20 μL volume. Real time PCR was performed using
QuantStudio 3 (ThermoFisher Scientific). mRNA expression was normalized to

Total RNA was isolated using the Qiagen Allprep RNA/DNA mini kit (Qiagen, 80204) or Qiagen RNeasy RNA micro kit (Qiagen, 74004). cDNA was synthesized using qScript cDNA SuperMix (total RNA >100 ng; VWR International, 95048–100) or SuperScript VILO Master Mix (total RNA <100 ng; Thermo Fisher Scientific, 11754050). mRNA levels of WNT4, FZD6, cyclin D1, and cMyc were quantified using real-time qPCR normalized to TATA-binding protein (TBP), as previously described (36 (link)). Each real-time qPCR assay was performed using cells isolated from at least three patient samples.

Three gels per condition were pooled, solubilized in Trizol (Invitrogen) and RNA isolated using the RNeasy Micro RNA kit with on column DNase I digestion as recommended by the manufacturer (Qiagen, Valencia, CA). RNA concentrations were determined using a BioRad Experion system with standard sensitivity RNA chips and 50 ng of total RNA was used to prepare cDNA using the iScript cDNA synthesis kit (Bio-Rad Laboratories, Hercules, CA). PCR reactions were carried out using iQ Supermix (BioRad) with primers specific for rat α-smooth muscle actin (α-SMA) (forward: 5′ GGAGTGATGGTT-GGAATGG 3′; reverse: 5′ ATGATGCCGTGTTCTATCG 3′) and control gene acidic ribosomal phosphoprotein (ARBP) (forward: 5′ TAGAGGGT-GTCCGCAATG 3′; reverse: 5′ GAAGGTGTAGTCAGTC-TCC 3′). Data were analyzed using the fold change method incorporating primer efficiency with the REST2009 program (Qiagen Inc., Valencia, CA).

Total RNA from cultured cells was extracted using an RNeasy Mini Kit or RNeasy Micro RNA Kit (Qiagen, Hilden, Germany) based on the manufacturer's instructions. Total RNA (1 μg) was used for cDNA synthesis using SuperScript BMP4 dose effect on human iPSCs J Kojima et al III (ThermoFisher Scientific). cDNA was used for TaqMan gene expression analysis. The primers used in this study are shown in Supplementary Table S1. For normalization, GAPDH was used as an internal control in the TaqMan array (and individual TaqMan probe assay). Genes that were clearly detected in two experiments were used for the assay.
For miRNA detection, a miRNeasy Micro Kit (Qiagen) was used for extraction of RNA and cDNA synthesis according to the manufacturer's instructions. miRNA was analyzed using a TaqMan Human MicroRNA array card A (ThermoFisher Scientific). U6 was used as an internal control.

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.
