A. Diagram of the major transcriptional regulators of SAN differentiation in the mouse embryo. Tbx5 activates Shox2 , Tbx3 and SAN-specific markers, including Hcn2 and Hcn4 . In addition, Shox2 inhibits Nkx2 .5 expression, and Tbx3 inhibits markers for the working myocardium. B. qRT-PCR data showing changes in the expression or timing of SAN related genes. Blue line indicates relative gene expression normalized to expression of Gapdh over time in wild-type R1 EBs and red lines indicate gene expression in Map3k7 -overexpressing EBs. Error bars indicate standard error from three technical replicates. Upregulation or downregulation of each gene was considered relevant only if relative expression trends were the same in each of a minimum of three biological replicates. Error bars represent standard error from three technical replicates. Statistical significance was determined by t-test. (*) represent p<0.006.

In Vivo Transplantation of HVPs under Renal Capsule (A) Schematic illustration of HVP generation, differentiation, and transplantation. HVPs were injected under the kidney capsule or intra-myocardially into the heart (injection site marked with squares); photos illustrate where the HVP graft was formed 2 months after transplantation, when it was recovered. (B) Electron microscopy of the HVP patch in the kidney capsule revealed mature ultra-structure, including organized and aligned sarcomeres, with well-defined Z-line, M-line, A-band, and I-band (left micrograph). Also apparent were desmosomes, mitochondria, myofilament bundles (middle panel), and capillaries containing red blood cells (right panel). (C) High-resolution immunofluorescence images further demonstrate sarcomeric organization within HVP grafts, with transverse orientation of a-actinin at z-lines and actin staining between z-lines. Membrane staining (WGA) revealed the presence of developing T-tubules (middle panels, high magnification of indicated region at right). (D) Immunofluorescence staining of the HVP kidney patch, with antibodies against MLC2a, MLC2v, cTnT, aSMA, ISL1, laminin, HCN4, human fibronectin, VE-cadherin, and Ki67. Scale bar, 200 μm. Red lectin was injected via the tail vein, illustrating a direct connection of the HVP kidney patch with the host venous system. Scale bar, 50 μm.

In Vivo Transplantation of HVPs into Healthy and Injured Hearts (A) White dashed box denotes the location of the HVP graft 8 months following intramyocardial injection into a healthy heart. (B) Immunofluorescence staining showed that HVP ventricular grafts in the heart expressed NKX2.5-GFP (green), MLC2v, connexin 43, and MHY11; a minority of cells co-expressed MLC2a and was negative for HCN4 and ISL1. CD31 was only present outside the graft. (C) The white dashed box identifies the localization and the engraftment of the xeno tissue 2 months after injection of the HVPs into the border zone of MI hearts. Red asterisks denote infarction site. (D) Immunofluorescence staining showed that HVP ventricular grafts in post-MI hearts co-expressed NKX2.5-GFP (green), connexin 43, human nuclei, MLC2v, MHY11, human fibronectin, and laminin. A minority of cells was positive for ki67; MLC2a, ISL1, and HCN4 staining was not observed. Endothelial marker CD31 was detected in close proximity to the HVP graft. (E) High-resolution imaging of the border zone of post-MI HVP grafts demonstrated engrafted, differentiated cardiomyocytes of human origin, with well-organized sarcomeres (stains of cell membrane [WGA, green], human mitochondria [red], and F-actin [orange]). (F) MRI assessment of post-MI hearts 2 months following HVP transplantation showed improved global and local function in comparison with placebo. Representative short axis images show wall thickness at the site of induced infarction (arrows). LV, left ventricle; RV, right ventricle. (G) Mean measurements ± SD of wall thickening, ejection fraction, and volume during end diastole (EDV) and end systole (ESV). *p < 0.05; **p < 0.01; n/s, not significant.

Coimmunoprecipitation of Thy1 and HCN4 by beads coated with anti-Thy1 antibody. Protein G-coated beads (Dynabeads, 100.03D; Invitrogen) were BS3-cross-linked to Thy-1 antibody and then incubated with lysate. Proteins were eluted from these beads, analyzed with Western blot, and sequentially probed for Thy1 (lanes a–d), HCN4 (lanes e–h) using polyclonal antibody, and ABCR (lanes i–l). Before the second and third probes, the previously applied primary antibodies were stripped with glycine. The material aliquoted into each SDS-PAGE gel lane is specified underneath by the combination of + and −. Lanes a, e, and i are material eluted from raw beads (without antibody coating and without lysate). Lanes b, f, and j are material eluted from antibody-coated beads without lysate. Lanes c, g, and k are proteins eluted from Thy1 antibody-coated beads incubated with lysate. Lanes d, h, and l are lysate alone. The migration distances of the molecular weight standards along the left apply to the lanes probed by Thy1 antibody. Those along the right apply to the lanes probed by HCN4 and ABCR antibodies.

Coimmunoprecipitation of Thy1 and HCN4 by incubation of beads, coated with monoclonal anti-HCN4 antibody, with lysates, formatted as in Figure 4. The proteins eluted from these beads were separated by SDS-PAGE, with samples of the lysate and molecular weight standards in adjacent lanes. The gels were analyzed with Western blot and the blots were separated into three segments by slicing at the level of the 185 kD standard and at approximately 50 kD. The upper, middle, and lower segments were probed with antibodies against ABCR, HCN4 (polyclonal), and Thy1, respectively. The ABCR and Thy1 antibodies were visualized with Fc fragment-specific, DyLight 649-conjugated, goat anti-mouse IgG. The HCN4 antibody was visualized with detection reagent (Clean-Blot IP; Thermo Scientific).
