Graphic abstract. Working model of enriched differentiation of SANLC from hiPSC by the BMP4 + PD + BMS (BPM) treatment versus the GiWi method alone. Simultaneous activation of BMP and inhibition of RA and FGF signaling pathways during cardiac mesoderm stage of the GiWi-induced hiPSC differentiation strongly favor a SAN-specific gene transcriptional landscape leading to enhanced pacemaker cell specification
