Check if the same lab product or an alternative is used in the 5 most similar protocols
Explant culture: HH3 chick embryo primitive streak is divided into six equal size portions, and the anterior primitive streak (cardiac progenitor cells) is deemed to be the second segment of explants from the cranial side (Fig. S4A). The explants of anterior primitive streaks were cultured in vitro in culture medium (DMEM-F12 GIBCO) at 37 o C and 5% CO2 [25] for 24, 48 or 72 hours. Each treatment was performed in triplicate. Approximately, 95% of the cells in the explant culture were determined to be cardiomyocytes in the control group, which shows the presence of myosin heavy chain using MF20 immunofluorescent staining as previously reported [26] .
Primary culture: Primary cardiomyocyte cultures were established from day 14 chick embryo hearts (DMEM-F12 GIBCO).
Cell culture: H9c2 cells was purchased from Guangzhou Jennio Biotech Co.,Ltd, China and cultured in culture medium (DMEM-F12 GIBCO).

Check if the same lab product or an alternative is used in the 5 most similar protocols
The choriocarcinoma trophoblast cell lines, BeWo, Jar, and Jeg‐3, were from American Type Culture Collection (ATCC). The non‐tumor trophoblast HTR‐8/SVneo was a gift from Prof. Charles Graham (Queen's University at Kingston, Canada). Human umbilical vein endothelial cells (HUVECs; originally from ATCC) and aortic endothelial cells (HAoECs; originally from PromoCell GmbH) were provided by Dr. Andriana Margariti and Prof. David Grieve, respectively (Queen's University Belfast, UK). BeWo cells were maintained in DMEM/F12 Gibco (Thermo Fisher) supplemented with 2 mmol/L L‐glutamate. Jar and HTR‐8/SVneo were cultured in RPMI 1640 (Sigma‐Aldrich), and Jeg‐3 was cultured in EMEM (ATCC). Both HUVECs and HAoECs were cultured in EGM‐2 (Lonza) with all vendor‐provided supplements in flasks or plates coated with 0.1% gelatin (Sigma‐Aldrich). All growth media contained 10% fetal calf serum. There was no mycoplasma contamination with the cells.

The normal intestinal epithelial cell line Caco-2 was purchased from American Type Culture Collection. The cells were cultured in Dulbecco's modified Eagle medium (DMEM)/F12 (Gibco; Thermo Fisher Scientific, Inc.) containing 10% fetal calf serum (FBS; HyClone; GE Healthcare Life Sciences) and 1% penicillin-streptomycin and were maintained at 37˚C with 5% CO2 in an incubator. Caco-2 cells were treated with 2% DSS at 37˚C for 4 days to construct the inflammatory model (18 (link)).

Using P2 mice, a 1–2 mm piece of tail was rinsed once in 70% ethanol and then twice in PBS containing 1X Antibiotic-Antimycotic (Gibco, 15240096). Next, tails were minced in 0.25 mL mixture of collagenase (Worthington Labs, LS004204, diluted in RPMI1640 plus L-glut, Gibco, 11875). After mincing, an additional 0.25 mL collagenase mixture was added, and the tissue was incubated for 30 minutes at 37°C. 6 mL MEF media (DMEM/F12 Gibco, 11330 + 10% FBS + PSG) was added, and tissues were incubated overnight at 37°C in 5% CO2. Cells were incubated for an additional 3 days to allow adherence and spread away from remaining tissue. Tissue pieces were removed using sterile instruments, and cells were split and cultured as described above.

Human MB cell lines D283 and UW-228 were originally obtained from the American Type Culture Collection (ATCC, Rockville, USA). These two cell lines present molecular features of different MB molecular subgroups: UW228 cells are TP53-mutated and classified as Shh, whereas D283 cells are p53 wild-type and classified as Group ¾ (Ivanov et al., 2016 (link)). The D283 cell line was cultured in Dulbecco’s modified Eagle’s medium (DMEM low glucose, Gibco, Grand Island, USA), while UW228 cell line was cultured in DMEM: Nutrient Mixture F-12 (DMEM/F-12 Gibco®), both medium supplemented with 10% (v/v) fetal bovine serum (FBS, Gibco) and 1% (v/v) penicillin/streptomycin (Gibco). Cells were incubated in a humidified atmosphere of 5% CO2 at 37°C.

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.
