The human cerebral microvascular endothelial cell line (hCMEC/D3) was donated by Professor Pierre Olivier Couraud (Institute of Cochin, INSERM, Paris, France).36 hCMEC/D3 cells were cultured in endothelial basal medium-2 (EBM-2) supplemented vascular endothelial growth factor (VEGF), human epidermal growth factor (hEGF), R3-insulin-like growth factor-1 (R3-IGF-1), ascorbic acid, hydrocortisone, human fibroblast growth factor-beta (hFGF-β), heparin (all from Lonza), and 2% human serum (Biosera). Primary NSCLC cells (A549 and COR-L105) were purchased from Sigma and metastatic NSCLC cells from cervical lymph nodes (NCI-H1299) from ATCC. Low-passage brain-metastatic NSCLC cell lines (SEBTA-001 and SEBTA-005) were established in house using biopsies from patients with lung-brain secondary tumors. All NSCLCs were cultured in Dulbecco′s modified Eagle medium supplemented with 2% human serum (Biosera) and maintained in 5% CO2 and humidified atmosphere at 37°C. All cell lines were subjected to routine mycoplasma testing, utilizing a kit from Lonza. Cell authentication was conducted using a microfluidic electrophoresis system incorporating an Agilent 2100 Bioanalyzer (Agilent Technologies\) to analyze STR-PCR fragments from 10 human genomic loci of human cell lines.37 (link)

Endothelial Cell Modulation and Kidney Cell Response

Check if the same lab product or an alternative is used in the 5 most similar protocols
The human dermal microvascular endothelial cells (HMVECs) were cultured in EBM-2 medium supplemented with EGM-2 which contained fetal bovine serum, 5.5 mmol/L-glucose, hydrocortisone, VEGF, R-IGF-1, hFGF-β, ascorbic acid, GA-1000, hEGF, and heparin (Lonza, Alpharetta, GA, USA). When the cells reached 70-80% confluence, TGFβ2 (5 ng/mL), N-FGFR1 (1.5 μg/mL), apelin (100 nM), or ML221 (10 μM) was added to the experimental medium (a mixture of HuMedia-MVG in serum-free RPMI 1640 medium at a 1 : 3 ratio).
Human HK-2 cells were cultured in MEM supplemented with 10% fetal bovine serum (Invitrogen, Carlsbad, CA, USA). To establish the conditioned medium experiment [8 (link)], HMVECs were transfected with scramble or apelin siRNA for 6 h, after which the medium was replaced with fresh EBM-2 medium. After incubation with fresh medium for 48 h, the experimental medium of HMVECs was harvested and transferred to cultured HK2 cells.

Human dermal microvascular endothelial cells (HMVECs, Lonza, Basel, Switzerland), maintained in EBM-2 medium supplemented with EGM-2 (glucose concentration 5.5 mmol/l, containing fetal bovine serum, hydrocortisone, hFGF-β, VEGF, R-IGF-1, ascorbic acid, hEGF, GA-1000 and heparin, Lonza, Alpharetta, GA), were used in this experiment. When the HMVECs on the adhesion reagent (Kurabo Medical, Osaka, Japan) reached 70% confluence, the media were replaced with the experimental media (HuMedia-MVG in serum-free RPMI-1640 at a 1:3 ratio) with or without mAb clone 9EG7 (5 μg/ml) for 1 h. In the control well, control mAb immunoglobulin G was added. Forty-eight hours later, protein lysate was harvested for western blot analysis.

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.
