Embryonic Angiogenesis Modulation

Check if the same lab product or an alternative is used in the 5 most similar protocols
Eggs with embryos were incubated at 37 °C in an incubator with 70% humidity. After 6 to 7 days of incubation, an air chamber was made, the shell membrane and chorioallantoic membrane were separated, and a window was opened on the shell membrane for injection. The CM from GC-shESM1 cells with or without recombinant ESM1, MAPK/ERK inhibitor SCH772984 (Selleck, Houston, TX, USA) or c-Met-inhibitor AMG-337 (Shanghai Ulva test), and the CM from GC cells with or without the ESM1-neutralizing antibody and MAPK/ERK stimulator Ceramide C6 (Santa Cruz, CA, USA) or MAPK/ERK inhibitor SCH772984 (Selleck, USA) were added to the loop by window injection. After 3 days, the CAM area was isolated, unfolded on a glass slide, and imaged under a stereomicroscope. Vascularization was assessed using image J/FIJI.

Check if the same lab product or an alternative is used in the 5 most similar protocols
1205Lu cells (donated by Dr. Meenhard Herlyn, Wistar Institute, Philadelphia, PA in 2005) were cultured in MCDB153 medium containing 2% FBS, 20% Leibovitz L-15 medium, with 5 μg/mL insulin. A375 cells (purchased from ATCC in 2005) were cultured in DMEM with 10% FBS. Cell lines were authenticated by sequencing at the NRAS and BRAF loci, and by STR analysis (completed July 2016). CRT cells were cultured in the same medium as parental cells with the addition of PLX4720 (1 μM) and PD0325901 (35 nM) (15 (link),16 (link)). These levels maintain the same RAF inhibitor to MEK inhibitor ratio as used for in vivo experiments. PLX4720 was provided by Dr. Gideon Bollag (Plexxikon Inc., Berkeley, CA). PD0325901, SCH772984, GSK461364, and BI 6727 were purchased from Selleck Chemicals (Houston, TX).

Check if the same lab product or an alternative is used in the 5 most similar protocols
DDP (P3494) and doxorubicin (D1515) were purchased from Sigma. Docetaxel (T1034) was purchased from TargetMol. Carboplatin (C805203) was purchased from Macklin, ERK inhibitor SCH772984 and Rac1 inhibitor NCS23766 was from Selleck.
The DDP prodrug was synthesized according previous report51 (link), by using the reaction between cis, trans, cis-[PtCl2(OH)2(NH3)2], and sebacic anhydride. The structure of this DDP prodrug was analyzed by proton nuclear magnetic resonance (HNMR) to confirm successful synthesis (Supplementary Fig. 8).

Modulation of Fibroblast-Macrophage Crosstalk

Check if the same lab product or an alternative is used in the 5 most similar protocols
Term human FM explants were collected as described above, rested in DMEM/F12 media supplemented with 10% FBS overnight and then treated with neutrophil CM for 24 hrs. In some experiments, FMs were pre-treated with the ERK inhibitor, SCH772984 (10nM, Selleckchem, Houston, TX); or the TLR9 antagonist, ODN2088 (TTAGGG, 1μM, Invivogen, A151, San Diego, CA) for 1 hr at 37°C prior to the addition of neutrophil CM. In other cases, DNase I derived from bovine pancreas (1U/ml, Roche, #10104159001, Roche, Switizerland) was added to neutrophil CM for 30 min at room temperature then the CM incubated at 70°C for 20 min and cooled prior to adding to the FMs. Neutrophil CM was incubated at 70°C for 20 min without DNase I as the baseline control. Incubation of activated neutrophil CM at 70°C for 20 min without DNase I did not affect its ability to alter FM function. After 24 hr of co-culture, the neutrophil CM and any associated factors was removed and FMs were transferred to a serum-free OptiMEM culture system for an additional 24 hrs to collect freshly secreted FM-derived factors for downstream analysis. FM supernatants and tissues are collected and stored at −80°C until 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.
