Human dermal microvascular endothelial cells, HMEC-1 (purchased from ATCC, Cat. No. CRL3243™), were cultured in MCDB 131 Medium (Thermo Fisher Scientific) supplemented with FBS (10%, Thermo Fisher Scientific), L-glutamine (2 mM, Thermo Fisher Scientific), hydrocortisone (0.05 mg/ml, Sigma-Aldrich), Epidermal Growth Factor (5 ng/ml), 100 U/ml penicillin, 10 μg/ml streptomycin, and 250 ng/ml amphotericin B (Sigma-Aldrich). HMEC-1 were cultured under standard conditions (37°C, 5% CO2) and passaged two times a week. In all experiments, cells between the second and tenth passages were used only when they reached full postplating confluency. Bardoxolone methyl (CDDO methyl ester, Cayman Chemical), dimethyl fumarate (Sigma-Aldrich), and L-sulforaphane (Sigma-Aldrich) initially diluted in DMSO were added to the culture medium at final concentrations of 100 nM, 300 nM, 500 nM, 1 μM, 3 μM, and 5 μM in triplicates, if not stated otherwise. Control cells were treated with 0.05% DMSO added to the culture medium. To check for acute toxicity, the cells were incubated with tested agents for 3 hours. Standard toxicity assessment time was set to 24 hours, according to the literature [30 (link)].

According to previously described methods,18 the thoracic aortas were removed from 6‐ to 9‐week‐old BALB/c mice after cervical dislocation and cut into 1‐mm‐thick rings. Each ring was placed on a prechilled 96‐well plate coated with 40 µl Matrigel and incubated at 37°C for 20 minutes. Then, additional 40 µl Matrigel was added and incubated at 37°C for 20 minutes. The embedded rings were incubated with 150 μl MCDB 131 medium (ThermoFisher) in the presence or absence of 20 ng/ml VEGF, with replacement of the medium every 2 days. In the cisplatin‐treated rings, cisplatin (5 µM) was added for 2 days, and cisplatin was withdrawn for subsequent incubation. In the VEGF + cisplatin + FIR group, cisplatin (5 µM) was added for 30 minutes, followed by exposure to FIRx2/day for 2 days. Then, the medium without cisplatin was replaced, and the treatment of the rings with FIRx2 was continued for 3 days. On day 5, the angiogenesis was evaluated by the capillary sprouts from aortic rings by using an inverted microscope equipped with a digital camera (SAGE VISION).

Cells were directed towards definite endoderm (DE) and primitive gut tube (PG) in MCDB 131 medium (cat# 10372-019, Thermo Fisher Scientific) with 1% 100x GlutaMAX, 1.5 g/L NaHCO3, 0.5% BSA, and a 10 mM final glucose concentration. Differentiation to DE was done in 3 days by daily adding 100 ng/mL Activin A (cat# 120-14, PeproTech) and 0.3 μM CHIR-99021 (reduced to 0 on the last day) (cat# S2924, Selleckchem). Further differentiation to PG was done in 2 days by daily adding 0.25 mM ascorbic acid (cat# A4544, Sigma) and 50 ng/mL FGF7 (cat# 100-19, PeproTech). The cells were analyzed by flow cytometry.

For differentiation, P2 organoids, which highly express PDX1 protein, were considered equivalent to hESC stage 3 (Rezania et al., 2014 (link)), washed with PBS (Mg/Ca free), and changed to MCDB131 medium (Thermo Fisher Scientific) supplemented with compounds as listed in Table S5 for 3 days each for stage 1 (S1)–S3 and 6 days for S4. Medium was changed daily. Samples were taken from each step for RNA analysis. Control organoids were kept in MCDB131 medium supplemented with 1× GlutaMAX.

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.
