Experimental details: Western blot was performed using Anti-CD43 Monoclonal Antibody (Product # 14-0439-82) and bands around 90-130 kDa corresponding to CD43 were observed in the cell lines tested except HT-29 which is reported to be negative. Membrane enriched extracts (30 µg lysate) of K-562 (Lane 1), MOLT-4 (Lane 2), HEL 92.1.7 (Lane 3), U-937 (Lane 4) and HT-29 (Lane 5) were electrophoresed using Novex® NuPAGE® 4-12 % Bis-Tris gel (Product # NP0322BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # LC2001) by XCell SureLock™ Mini-Cell and XCell II™ Blot Module (Product # EI0002). The blot was probed with the primary antibody (1:500 dilution) and detected by chemiluminescence with Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:4000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using SuperSignal™ West Dura Extended Duration Substrate (Product # 34076).

Experimental details: Extended Data Figure 2 FGRS-transduction and vascular-induction reprogram HUVECs, but not hES-ECs, to proliferating functional rEC-MPPs A. Multi-colony niche-like structure that physically separates developing hematopoietic colonies from surrounding E4EC vascular niche . The emerging multi-colony sinusoidal-like structures create a unique cellular interface between E4EC monolayers and transduced ECs giving rise to hematopoietic clusters (n=4, scale bar is 1000 um.) B. Expansion potential of reprogrammed CD45 + hematopoietic cells . CD45 + (12x103) and CD45- (60 x10 3 ) cells were sorted into separate wells and expanded for two days. We observed 5-fold expansion of CD45 + cells (56.6 x10 3 +-7.9 x10 3 ; n=3) and dramatic reduction of CD45 - cells number (4.6x10 3 +-1.0 x10 3 ; n=3). C . Clonal expansion of CD45 + cells. CD45 + cells were FACS sorted into 96-well plates at the density of 1 and 2 cells/well. After seven days of culture, we observed CD45 + cell expansion in 6.3+-2.1 wells (93.1+-14.5 cells/well) of 1-cell sort and 29.0+-4.3 wells (112.1+-21.2 cells/well) of the 2-cell sort (n=3). The difference between cell number in 1 and 2-cell sort was statistically not significant (p=0.78) suggesting that the difference in the number of wells with detected cell expansion was rather due to survival of sorted cells than a reflection of the number of cells sorted into a well.

( A) : Cell counts throughout the erythroid differentiation protocol of control H1 hESCs (H1) and H1 hESCs transfected with a vector containing either wild type KLF1 (H1-KLF1) or the mutant form of KLF1 (H1-R328L). (B) : Total number of CFU-Cs generated from differentiating H1, H1-KLF1, and H1-R328L hESCs at day 10 of the differentiation protocol. (C) : Flow cytometry analysis of differentiating H1, H1-EKLF, and H1-R328L hESC at day 10 of the differentiation protocol using antibodies against CD34 and CD43 to mark hematopoietic progenitor cells (HPCs). (D) : Quantification flow cytometry data showing the %CD34 + /CD43 + HPCs at day 10 of the differentiation protocol. All data represents the mean of at least three independent experiments with error bars representing SEM. p values were calculated using two-way ANOVA followed by Tukey's multiple comparisons test (A) or one-way ANOVA followed by Holm-Sidak's multiple comparison test (B and D) (* p < .05).

Experimental details: Monitoring hematopoietic progenitor production throughout the differentiation protocol. Representative flow cytometry analysis of cells from days 0 to 24 of the differentiation protocol using antibodies against CD34 and CD43 (A) and the quantification of the percentage positive (B) was performed from at least three independent experiments. Absolute cell numbers of the differentiation represented in (A) are shown for days 3 and 10 (C) . Representative colonies generated from day 7 (Di-Div) and day 10 (Dv-Dviii) cells are shown, CFU-C activity having been assessed by methylcellulose assays on days 7 and 10 (E) .

Experimental details: CFU-C activity was enriched within the CD34 hi CD43 + cell population. CD34 + cells from day 7 cultures (A) and CD43 + cells from day 10 cultures (C) were sorted using magnetically activated cell sorting enrichment and reanalyzed by flow cytometry to assess purity (unsorted [red], enriched positive cells [blue], and flow-through low/negative cells [green]). Hematopoietic activity was quantified by plating these cell populations in CFU-C assays (B, D) . Day 10 cultures were stained for both CD34 and CD43 (E) and CD43 + /CD34 - , CD43 + /CD34 + double-positive, and CD43 - CD34 - double-negative cells were plated in CFU-C assays to quantify their hematopoietic activity (F) .
