Experimental details: Western blot analysis of Nanog was performed by loading 80 µg of NCCIT, NTERA-2 and negative control HeLa whole cell lysates onto a 4-20% Tris-HCl polyacrylamide gel. Proteins were transferred to a PVDF membrane and blocked with 5% BSA/TBST for 1 hour. Membranes were probed with a rabbit polyclonal antibody recognizing Nanog (Product # PA1-097) at a dilution of 1:2000 overnight at 4°C on a rocking platform. Membranes were washed in TBS-0.1%Tween 20 and probed with a goat anti-rabbit-HRP secondary antibody (Product # 31460) at a dilution of 1:20,000 for one hour. Membranes were washed and chemiluminescent detection performed using Pierce Super Signal West Pico (Product # 34078).

Experimental details: Western blot analysis was performed on tissue extracts (30 µg lysate) of (Fig. a) Mouse Spleen (Lane 1) and Mouse Testis (Lane 2), (Fig. b) Human iPSCs (Lane 1) and Human iPSCs derived definitive endoderm (Lane 2). The blot was probed with Anti- Nanog Polyclonal Antibody (Product # PA1-097X, 1:1000 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/ml, 1:4000 dilution). A 38 kDa band corresponding to Nanog was observed across the tissues tested (Fig. a) and human iPSC cells but not in human iPSC derived definitive endoderm (Fig. b) which is reported to be negative for Nanog expression.

Experimental details: Immunohistochemistry analysis of Nanog showing staining in the nucleus of paraffin-treated human testicular carcinoma (right) compared with a negative control in the absence of primary antibody (left). To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a Nanog polyclonal antibody (Product # PA1-097) diluted by 3% BSA-PBS at a dilution of 1:500 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

Experimental details: Chromatin immunoprecipitation analysis of Nanog was performed using cross-linked chromatin from 1x10^6 HTC-IR rat hepatoma cells treated with insulin for 0, 10, and 30 minutes. Immunoprecipitation was performed using a multiplex microplate Matrix ChIP assay (see reference for Matrix ChIP protocol: http://www.ncbi.nlm.nih.gov/pubmed/22098709) with 1.0 µL/100 µL well volume of a Nanog polyclonal antibody (Product # PA1-097). Chromatin aliquots from ~1x10^5 cells were used per ChIP pull-down. Quantitative PCR data were done in quadruplicate using 1 µL of eluted DNA in 2 µL SYBR real-time PCR reactions containing primers to amplify -15kb upstream of the Egr1 gene or exon-1 or exon-2-3 of Egr1. PCR calibration curves were generated for each primer pair from a dilution series of sheared total genomic DNA. Quantitation of immunoprecipitated chromatin is presented as signal relative to the total amount of input chromatin. Results represent the mean +/- SEM for three experiments. A schematic representation of the rat Egr-1 locus is shown above the data where boxes represent exons (black boxes = translated regions, white boxes = untranslated regions), the zigzag line represents an intron, and the straight line represents upstream sequence. Regions amplified by Egr-1 primers are represented by black bars. Data courtesy of the Innovators Program.

Experimental details: Figure 2 Morphology and characteristics of hMB-SLCs. (a) hMB-SLCs were cultured for 48 h in the absence or in the presence of 8 mu M RA which induces SLCs differentiation, highlighted by morphological changes and cell adhesion. (b) Western blot analysis confirmed that 48 h exposure of hMB-SLCs to 8 mu M RA induced a strong reduction in the stemness markers Nanog and OCT4 while increasing the differentiation markers, beta -3-Tubulin and GFAP. (c) qPCR analysis of OCT4 , Nanog , KLF4 , beta-3-Tubulin , GFAP, and BMP4 was conducted before and after RA treatment. mRNA expression levels are indicated as fold changes with respect to hMB-SLCs. (d) Gene expression of stemness, differentiation, and proliferation markers in hMB-SLCs with respect to RA-treated cells. * denotes p < 0.05 versus hMB-SLCs, ** denotes p < 0.01 versus hMB-SLCs, and *** denotes p < 0.001 versus hMB-SLCs.

Experimental details: Figure 1 FTH1 silencing influences hESCs pluripotency. ( A ) Alkaline phosphatase (AP) staining of colonies in SCR control and in hESCs transfected with lentiviral shFTH1 shows that FTH1-silenced ES colonies contain less AP+ cells; scale bar, 250 um; ( B ) Undifferentiated SCR and FTH1-KD hESCs were stained for Oct4 (green), Nanog (red), TRA-1-60 (green), and Sox2 (red) expression, while nuclei were counterstained with 4'.6-diamidino-2-phenylindole (DAPI). Scale bars, 50 mum. No significant differences were detected between the two groups with the exception of Nanog, which shows a slight positivity in FTH1-silenced cells; ( C ) The levels of Nanog protein were assessed by immunoblotting (IB). Band intensity analysis shows a higher level in FTH1-KD cells compared to SCR control. Actin levels were evaluated to confirm equal loading control; ( D ) mRNA levels of pluripotency-associated genes NANOG , OCT4 , and SOX2 were measured in undifferentiated SCR and FTH1-KD hESCs via qRT-PCR; ( E ) left panel: mRNA levels of endodermal ( AFP ), mesodermal ( Nkx2.5 ), and ectodermal ( PAX6 ) genes were measured in undifferentiated SCR and FTH1-silenced hESCs via qRT-PCR analysis; AFP and Nkx2.5 expression levels were higher in shFTH1 cells, while the expression levels of PAX6 were significantly diminished in silenced cells; ( E ) right panel: mRNA levels of endodermal ( GATA4 , FOXA2) , mesodermal ( HAND1 , CD31 ), and ectodermal ( NESTIN , PAX6 ) genes were measured in SCR and FTH1-KD emb

(A) Dermal fibroblasts derived from patient with SLE were reprogrammed into iPSCs using Sendai virus vectors and three clones (#1, #2 and #3) were characterized. RT-PCR confirms the loss of transgenes in hiPSCs-SLE (lanes 1, 2 and 3), presence (lane 4) in infected fibroblasts (ipF-SLE) and absence of Sendai viral transgenes in parental fibroblasts (pF-SLE) (lane 5). Full-length gels are presented in File S2 . (B) The hiPSCs-SLE colonies expressed alkaline phosphatase. Scale bar, 500 mum. (C) RT-qPCR analysis of pluripotency genes OCT4 , NANOG , SOX2 and REX1 was performed in fibroblasts and in hiPSCs derived from patient with SLE. All expression values are normalized to GAPDH and relative donor fibroblasts. Data are mean +- SEM and all statistical analysis was made between hiPSCs-SLE clones and relative fibroblasts by Student's t test showing P -values
