MenSC and umbilical cord (UC) MSC were isolated from menstrual fluid of the umbilical cord of three different healthy donors each and characterized according to ISCT31 (link) criteria as we have previously described15 (link),22 (link),32 . Human dermal fibroblasts were purchased from Lonza (cat. CC-2511, Lonza, Walkersville, MD USA). Human umbilical cord vein endothelial cells (HUVEC) and human microvascular endothelial cell line (HMEC-1) were obtained from the American Type Culture Collection (ATCC, Manassas, VA, USA). HUVEC and fibroblasts were cultured in Dulbecco’s Modified Eagle’s Medium (DMEM) (15-018-CV, Corning, New York, USA) supplemented with 10% fetal bovine serum (FBS) (Lonza, Walkersville, MD USA), 1% Penicillin/Streptomycin (P/S) (Life Technologies, Carlsbad, CA, USA) and 1 mM L-glutamine (Life Technologies). HMEC-1 cells were cultured in endothelial cells growth media 2 (EGM-2) (cc4147, Lonza). All cells were regularly tested for mycoplasma contamination using a mycoplasma detection kit (G238, Applied Biological Materials Inc., Richmond, BC, Canada). All cells were cultured in humidified incubation chambers at 37 °C with 5% CO2.

Exosome Modulation of Cytokine Release

To determine the effect of exosomes on cytokine release from target cells, exosomes were isolated from extravillous trophoblast cell-condition media and incubated with cells under either 8% or 1% O2. sEVs (20, 40, 80 and 100 μg protein/ml equivalent to 1 to 10 × 108 vesicles per ml) were then incubated with endothelial cells (HMEC-1, from Lonza) in medium containing 5 mM d-glucose under an atmosphere of 8% O2 to mimic the physiological conditions for 24 h. Cytokine release, defined as the accumulation of immunoreactive cytokine in cell-conditioned medium, was quantified using a protein solution array assay, as previously described (20 (link)).

Overexpression of Codon-Optimized ELTD1 in Endothelial Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human umbilical cord endothelial cells (HUVECs) and human microvascular cells (HMEC-1) were purchased from Lonza (Basel, Switzerland) and cultured in their EGM2 and EGM2-MV media respectively. IL8 and IL1a (R&D Systems, Minneapolis, MN, USA) were added to cells at 10 ng/mL. IL1-receptor antagonist (Sigma, St. Louis, MO, USA) was added at 1 μg/mL. The endogenous sequence of ELTD1 is poorly expressed therefore the cDNA was codon optimised using the JCat bioinformatics tool (http://www.jcat.de/) (accessed on 31 November 2017) without altering the amino acid coding sequence. Codon optimised ELTD1 (coELTD1) and HA-tagged coELTD1 were cloned into pLenti6.2V5DEST (ThermoFisher, Waltham, MA, USA) and the vector alone was used as a control. Virus was produced in 293T and concentrated by ultracentrifugation using standard techniques. The viruses were titred using blasticidin resistance and endothelial cells infected at MOI 5 for all experiments.

Modeling Endothelial Dysfunction in Diabetes

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human microvascular endothelial cells (HMEC-1) (iCell Bioscience Inc., Shanghai, China) were cultured in EGM-2MV medium (Lonza, Basel, Switzerland) supplemented with fetal bovine serum (FBS) and growth factors at 37 °C in the presence of 5% CO2 in the air. To mimic diabetes in vitro, HMEC-1 cells were subjected to endothelial basal medium (EBM-2, Lonza) containing 25 mmol/L d-glucose (Aladdin, Shanghai, China) (high glucose, HG). To simulate ischemia-induced tissue starvation, cells were cultured in medium supplemented with no additional growth factors (nutrient deprivation, ND) (Caporali et al. 2011 (link)). Cells incubated with d-Mannitol (normal glucose, NG) and EGM-2MV medium supplemented with FBS and growth factors served as controls.
Prior to cell seeding, cells were infected with prepared Ad-AURKAOE or Ad-NCOE at a multiplicity of infection of 10 for 48 h. Cells were then detached and re-seeded on plates for subsequent analyses under different stimuli as described above.

U-87 MG glioblastoma cell line (cancerous),
HMEC-1 (noncancerous endothelial cells), and NHDF (noncancerous fibroblasts)
were purchased from the American Type Culture Collection (ATCC) and
Lonza, respectively. U-87 MG cells were cultured in EMEM with 10%
FBS, 2 mM glutamine, and 1% (100 U/mL) penicillin–streptomycin;
HMEC-1 cells were cultured in MCDB 131 with 10% heat-inactivated FBS,
2 mM glutamine, 1% penicillin–streptomycin, and 10 ng/mL epidermal
growth factor (EGF human protein) and NHDF in fibroblast growth medium
supplemented with fibroblast growth kit (Lonza), respectively. U-251
MG glioblastoma cells transfected with dsRed66 (link) were kindly provided by Manon Carré and cultured in DMEM
with phenol red, 2 mM glutamine, 10% FBS, and 1% penicillin–streptomycin.
All cells were routinely maintained at 37 °C and 5% CO2.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
