Ear biopsy (or sperm from mosaic males, taken directly from the uterus of a euthenased female on the day following coitus) was used to prepare genomic DNA as previously described (Arthur et al., 2000 (link)). Mouse genotypes were determined by PCR analysis using primers w and x above, Cre primers Cre-F (GATCGCTGCCAGGATATACG) and Cre-R (AATCGCCATCTTCCAGCAG) which gives a PCR product of 574 bp when a Cre transgene is present; Primer-y (GGTCAGCCAGTCTAGCCAAG) and primer-z (GTGGTTGCCATTCAAGTGTG) amplify products of 411 bp for the wild type allele and 566 bp for the bi-floxed Endoglin allele. PCR using primer-x with primer-y gives a product of 602 bp only in the presence of the EngΔex5-6 allele, and no detectable PCR product is amplified from a wild-type allele.

Mice were euthanized and 0.8 ml of dispase (1 mg/ml; Invitrogen, Paisley, UK) was instilled intratracheally, after which lungs were excised, finely minced, and digested with dispase at 37°C for 45 min. Samples were then triturated by pipetting and filtered through a 40-μm sieve (BD Biosciences, Oxford, UK), to produce a lung single-cell suspension. Lung endothelial cells (LEC) were obtained by a two-step magnetic affinity cell-sorting procedure (Miltenyi Biotech, Surrey, UK), comprising of a first step of leukocyte depletion using biotinylated anti-CD45 MAb (eBioscience, Hatfield, UK) followed by LEC enrichment with biotinylated anti-CD31 (PECAM-1) MAb (eBioscience). Purified LEC (CD31+, CD45) were cultured in gelatin-coated flasks in DMEM with 10% FCS, 12 U/ml heparin, 25 mM HEPES, 75 μg/ml endothelial cell growth supplement (Sigma, Poole, UK), 1% sodium pyruvate, 1% nonessential amino acids, and penicillin-streptomycin, passaged with trypsin-EDTA, and used for experiments between passages 3 and 10. The phenotype of cultured cells was determined by flow cytometry on the basis of staining for CD31 and other surface markers constitutively expressed on endothelial cells including: VE-cadherin, ICAM-1, ICAM-2, endoglin, and CD34, as well as expression of inducible markers VCAM-1 and E-selectin.

Immunofluorescence staining was performed as described [33 (link), 83 (link), 84 (link)]. Briefly, exponentially growing cells were fixed with 4% paraformaldehyde (PFA) for 10 min, washed with PBS and permeabilized with 1% NP-40 for 10min at room temperature. After being blocked with 10% donkey serum (Jackson Immuno-Research Laboratories, West Grove, PA) for 1h at room temperature, cells were incubated with various primary antibodies, including CD29, CD73, BMPRII, CD90, CD117/c-kit, CD105/endoglin, or BMPR-II antibody (all from Santa Cruz Biotechnology) for 1h at room temperature. Cells were washed with PBS and incubated with FITC-labeled secondary antibodies (Jackson ImmunoResearch Laboratories) for 30 min. DAPI (Invitrogen) was used to visualize nuclei. Stains were examined under a fluorescence microscope. Negative control cells were performed under the same conditions without primary antibodies. Representative images from at least three independent staining experiments are shown.

βTC-3 and LLC-RFP cells (a gift from V. Mittal, Weill Cornell Medical College, New York, NY) were maintained in RPMI and DMEM (Invitrogen), respectively, supplemented with 10% FCS. EO771 cells (a gift from R. Ray, Saint Louis University School of Medicine, St. Louis, MO) were cultured in DMEM low glucose supplemented with 20% FCS. MS1 and bEND3.1 cells were cultured in Endothelial Cell Basal Medium MV2 kit (PromoCell). Primary endothelial cells from EngiKOe mice carrying the Immortomouse transgene were isolated from the lung (MLEC) and propagated in endothelial cell medium containing 20 U/ml recombinant mouse interferon-γ (PeproTech) at 33°C. All experiments using MLEC were performed at 37°C. Induction of knockout of the endoglin gene was achieved by growing MLEC in endothelial cell medium containing 1 µM 4-OH-tamoxifen (Sigma-Aldrich) for 48 h. Expression of endoglin, Twist, and CD31 was stably knocked down in endothelial cells by lentivirally transduced shRNA-containing vectors (Santa Cruz Biotechnology, Inc.).

Mouse E14 (129/ola) ES cells were electroporated with linearised targeting vector and selected in G418-containing medium. The genotypes of G418-resistant ES clones were first analyzed by PCR using the following primers (all DNA sequences are written in the 5′ to 3′ direction and approximate locations are illustrated in the Figures). Primer-u (ATGTGGCAGGTCTCAAGGTG) and Primer-v (ATCGCCTTCTATCGCCTTC) amplify a 1.8 kb product specific to the targeted recombinant allele, whilst primer-w (GACGCCATTCTCATCCTGC) and primer-x (CCACGCCTTTGTCCTTGC) amplify products of 430 bp from the wild type Endoglin allele and 500 bp from the floxed Endoglin allele. Amplification was performed for 35 cycles with 15 s at 96°C, 30 s at 58°C, and 60 s at 74°C. Further Southern blot analysis used 3′ and 5′ external probes to hybridize to EcoRI digested genomic DNA, as previously described (Arthur et al., 2000 (link)). Ultimately two of 40 (5%) G418-resistant ES clones were found to be homologous recombinants and microinjected into C57BL/6 blastocysts. The resulting chimeras were bred to C57BL/6 females, and germline transmission of the floxed Endoglin allele was obtained.

CRC specimens were obtained from 20 patients (see Table S1) during therapeutic surgery at the Surgical Oncology Unit, IRCCS Ospedale Policlinico San Martino, Genoa, upon signed informed consent (Institutional and Regional Ethic Committee approval, PR163REG2014, renewed in 2017). This cohort of CRC patients was composed of newly-diagnosed patients without any kind of therapeutic treatment before surgery. Samples were anonymized as reported and referred in the paper with the year and serial number for brevity [33 (link)]; all these CRC-TAF have been used within the 8–9th culture passage.
Primary TAF lines were obtained by mincing CRC mucosa, enzyme digestion and debris removal by soft centrifugation as reported [35 (link)]; cell suspensions were then purified by density gradient centrifugation (Lympholyte, Cederlane, Burlington, ON, Canada) and seeded in culture wells for 36 h. Non-adherent cells were removed and adherent cells showing a fibroblast-like morphology were cultured for an additional 7 d in MEMalpha (Euroclone, Milan, Italy) supplemented with 10% foetal calf serum (FCS, Sigma Chemicals Co., St. Louis, MO, USA). At confluence, cell cultures were split and expanded as described [19 (link),31 (link)]. Phenotype for Intercellular Adhesion Molecule 1 (ICAM1), Fibroblast Activation Protein (FAP), Thy-1 Cell Surface Antigen (CD90), Endoglin (CD105), Epidermal Growth Factor Receptor (EGFR) and Epithelial Cell Adhesion Molecule (EPCAM) markers were analyzed by indirect immunofluorescence at different time points, along a culture period of two months as described in Section 2.5. TAF were also tested for the expression of BTN3A1 and BTN2A1.

The concentration of hsEng present in mice and human plasma was determined using a Human Endoglin/CD105 Quantikine ELISA kit (DNDG00, R&D Systems, Minneapolis, MN, United States) according to the manufacturers’ instructions in duplicates. Transgenic mice express variable levels of human soluble endoglin (hsEng), so mice expressing plasma levels of hsEng above the 500 ng/mL threshold were selected. On the other hand, their wild-type (WT) littermates presented undetectable hsEng levels in plasma.
Plasma levels of mouse sEng (msEng) levels were determined by Mouse Endoglin/CD105 Quantikine (MNDG00, R&D Systems, Minneapolis, MN, United States) ELISA Kit, used according to the manufacturer’s instructions, in duplicates.
