HuMSCs were purchased from Beijing Beina Chuanglian Biotechnology Institute. Cells were cultured in 25-cm2 culture flasks containing HyClone™ Dulbecco's modified Eagle's medium (HyClone; GE Healthcare Life Sciences), supplemented with 10% fetal bovine serum (Gibco; Thermo Fisher Scientific, Inc.), 100 U/ml penicillin and 100 µg/ml streptomycin (Gibco; Thermo Fisher Scientific, Inc.). Cells were grown at 37°C under 5% CO2 atmosphere. The culture medium was replaced every 3 days and the HuMSCs were digested with trypsin (Gibco; Thermo Fisher Scientific, Inc.) once they reached 70–80% confluency. The cells in the fourth passage were used for further differentiation. Before hepatic differentiation, the multipotency of the cultured HuMSCs was confirmed by differentiation experiments. The cells were treated with osteogenic medium containing L-glutamine, decamethasone, ascorbate and β-glycerophosphate (Sigma-Aldrich; Merck KGaA) and chondrogenic medium containing h-Insulin, L-glutamin, dexamethasone, indomethacin and 3-isobuty-I-methyl-xanthine (Sigma-Aldrich; Merck KGaA) according to previous studies (15 (link),16 (link)).

Preparation and Fixation of Retinal Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
The eyes were dissected in refrigerated HyClone Dulbecco’s Modified Eagles Medium (GE Healthcare Life Sciences, Logan, UT). The eyecups were then immersion-fixed in 4% (w/v) paraformaldehyde (PFA) in 0.1 M phosphate buffered saline (PBS), pH 7.4 for 45 minutes to 1 hour and cryoprotected overnight in 30% sucrose. These eyecups were sectioned at 16–20 μm with a Leica cryostat (Leica Microsystems, Buffalo Grove, IL) and mounted onto slides, which were stored at -20°C. For whole-mounted retinas, the sclera was removed and the retina was flattened photoreceptor side down on black filter paper (EMD Millipore Corporation, Bedford, MA). The retina was subsequently immersion-fixed in 4% PFA in 0.1 M PBS for 1 hour. The whole-mounted retina was stored in 0.1 M PBS until processing for immunohistochemistry.

Four CRC cell lines (SW480, HCT116, HT29, and SW620) and an intestinal epithelial cell line (NCM460) were donated by Dr Jinjun Rao (College of Pharmacy, Southern Medical University, Guangzhou, China). The cancer cell lines were incubated in Gibco RPMI-1640 medium (Thermo Fisher Scientific, Waltham, MA, USA) while NCM460 cells were cultured in HyClone Dulbecco’s Modified Eagle’s Medium (GE Healthcare Life Sciences, Logan, UT, USA); both types of media were supplemented with 10% HyClone fetal bovine serum (FBS; GE Healthcare Life Sciences). Cells were cultured at 37°C in a humidified environment containing 5% CO2.

Bone marrow-derived macrophages (BMDM) were cultured for 6 days in HyClone™ Dulbecco's Modified Eagles Medium (GE Healthcare Life Sciences, Missassauga, Ontario, Canada) conditioned with medium from L926 cells, as we described (Chen et al., 2015) and treated with lipopolysaccharides (LPS; Sigma-Aldrich, Oakville, Ontario, Canada, 100 ng/mL) with or without Dabrafenib (10 μM) for 4 hours. RNA was isolated for quantitative reverse transcription-polymerase chain reaction (qRT-PCR) analysis.

Cell lines and culture. Human breast cancer cell lines (MCF-7, BT474, MDA-MB-231, and MDA-MB-468), normal breast epithelial cell line MCF-10A and 293T cells were purchased from the American Type Culture Collection (Manassas, VA, USA). BT474 and MDA-MB-231 cells were cultured in Hyclone RPMI-1640 medium (GE Healthcare Life Sciences, Logan, UT, USA) while MCF-7, MDA-MB-468, MCF-10A and 293T cells were cultured in Hyclone Dulbecco's modified Eagle's medium (GE Healthcare Life Sciences). All cells were grown in medium containing 10% fetal bovine serum (Hyclone; GE Healthcare Life Sciences) supplemented with 1% penicillin-streptomycin (Gibco; Thermo Fisher Scientific Inc., Waltham, MA, USA) in a humidified atmosphere of 5% CO 2 at 37˚C.

To detect cell viability following exposure to various concentrations (0, 5, 10 and 20 mmol/l) of OP-B (Jrdun Biotechnology Corp., New York, NY, USA), 100 μl SGC-7901 cells (5×104/ml) were seeded in 96-well plates and were cultured for 0, 12, 24, 48 and 72 h at 37°C. Subsequently, 100 μl serum-free Dulbecco's modified Eagle's medium (Hyclone; GE Healthcare Life Sciences) containing 10% Cell Counting kit (CCK)-8 reagents (v/v) (Dojin Laboratories, Kumamoto, Japan) was added to each well, and the cells were cultured for 1 h in a 5% CO2 atmosphere at 37°C. Optical density was then measured at 450 nm using a Model 550 microplate reader (Bio-Rad Laboratories, Inc., Hercules, CA, USA).

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.
