hADSCs and hUCMSCs were seeded in 10-cm dish plates at a density of 5×10
4 cells/mL. Then, 100 ng/mL Activin A (CB031-0033; Shanghai ExCell Biology, Shanghai, China) was added to complete medium when the cells reached 50% confluence. The next day, cells were induced by the liver differentiation medium for 1 week. The hepatic differentiation medium contained 100 ng/mL HGF (10463-HNAS; Sino Biological), 20 ng/mL EGF (236-EG-200; R&D), 20 ng/mL IGF (291-G1-200; R&D), 20 ng/mL FGF-4 (CB055-0343; Shanghai ExCell Biology), 10 μg/mL Insulin-Transferrin-Sodium Selenite Supplement (11074547001; Roche, Basel, Switzerland), 1 μM dexamethasone (D4902-25MG; Sigma-Aldrich, St Louis, USA), 2 mg/mL fetal bovine serum (FBS 126575-10GM; Millipore, Billerica, USA), 1% penicillin-streptomycin (15070-063; Gibco) and DMEM-F12 medium (C11330500BT; Gibco). They were then transferred to a hepatic maturation DMEM-F12 medium that contained 40 ng/mL HGF, 20 ng/ml EGF, 20 ng/ml IGF, 20 ng/mL FGF-4, 10 μg/mL ITS, 1 μM dexamethasone, 1 mM nicotinamide (N0636-100G; Sigma-Aldrich), 20 ng/mL OSM (0452-HNAH; Sino Biological), 2 mg/mL FBS and 1% penicillin-streptomycin.

Originally, PANC-1 and MIA-Paca-2 cells were cultured in DMEM supplemented with 10% FBS, then dissociated with trypsin solution. Dissociated single cells were transported to Falcon 5 mL polystyrene test tubes and washed twice with phosphate buffer solution (PBS). The cells were then analyzed on a flow cytometer (FACS Aria II, Becton Dickinson, San Diego, CA, USA). Then, PANC-1 and MIA-Paca-2 cells were separately sorted into ultra-low cluster 96-well plate with 200 μL sphere formation medium (SFM) added per well at the concentration of 100 cells/well. The SFM consisted of DMEM/F12 medium (11330-032, Gibco) supplied with 20 ng/mL epidermal growth factor (EGF, 236-EG-200, R&D Systems, Minneapolis, MN, USA), 20 ng/mL basic fibroblast growth factor (bFGF, 233-FB-025, R&D Systems), B27 supplement (17504044, Gibco) and N2 supplement (17502048, Gibco). Subsequently, cells were cultured at 37 °C in a 5% CO2 humidified environment and imaged with an Operetta CLS high-content imaging system (PerkinElmer) every other day.

For the Afatinib assay, BCPAP and KTC-1 Cells (4×105) were incubated with 100 ng/ml EGF (236-EG-200; R&D Systems) for 20 min, and then incubated with or without 1 μmol/L Afatinib (S1011; Selleckchem) for 2 h. For the PLX4032 assay, BCPAP and KTC-1 Cells (4×105) were also incubated with 100 ng/ml EGF for 20 min and then incubated with or without 2 μmol/L PLX4032 (S1267; Selleckchem) for 4 h. After Afatinib and PLX4032 treatment, BCPAP and KTC-1 Cells were washed with ice-cold PBS three times, and whole-cell lysates were subjected to SDS–PAGE and incubated with p-EGFRY845, p-ERK1/2, t-ERK1/2, SLUG, ZEB1, ZEB2, and β-actin antibodies, respectively.

Differentiating d-USC into RPTEC

Check if the same lab product or an alternative is used in the 5 most similar protocols
To evaluate the plasticity and differentiation capability of d-USC, we induced these cells to differentiate into human renal tubular epithelial cells (RPTEC). Both d-USC and USC (1,000 cells/cm2, at p5) were induced to differentiate into RPTEC for 14 days, respectively. Renal tubule epithelial differentiation media consisted of a mixture of conditioned medium collected from cultured RPTEC and USC culture medium containing 30 ng/mL epidermal growth factor (EGF, 236-EG-200, R&D Systems) in a 1:1 ratio. The differentiation medium was replaced every third day. Cell morphology was observed before and after induction. Human RPTEC (ATCC® PCS-400-010™) were cultured as a positive control.

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.
