G csf

Manufactured by Fujifilm
Sourced in Japan

G-CSF is a type of lab equipment used in medical research and clinical settings. It is used to produce a specific protein that stimulates the growth and development of white blood cells. The core function of G-CSF is to assist in the production and maturation of certain types of white blood cells, which play a crucial role in the body's immune response.

Generation of iPSCs from Peripheral Blood

Mononuclear cells (MNCs) were isolated freshly from the peripheral blood of the AD patient and normal subject using the Ficoll-Paque™ PLUS method (GE Healthcare, USA). Isolated peripheral-derived MNCs (PBMCs) were cultured for 4 days in MNC media containing 50 ng/ml interleukin-6 (IL-6), 50 ng/ml stem cell factor (SCF), 10 ng/ml thrombopoietin (TPO), 20 ng/ml Flt3 ligand (Flt-3L), 20 ng/ml interleukin-3 (IL-3), and 10 ng/ml granulocyte colony-stimulating factor (G-CSF) (all from WAKO, Japan) in StemFit AK03 medium (kindly provided by Ajinomoto, Japan). The MNCs were then infected with SeVdp (KOSM) 302L at MOI of 3~10 [8 (link)] and transferred into 6-well dishes coated with iMatrix-511 (Matrixome, Japan). From the next day, 500 ul of StemFit AK03 medium was added every day for 4 days, after which the medium was fully changed every other day until iPSC-like colonies emerged. Sub-culturing and expansion of the cells was then undertaken until the generated iPSCs became stable for characterization and storage, normally at passage 10.

Isolation and Culture of AML Cells

Samples were prepared from peripheral blood collected from newly diagnosed and untreated AML patients. Mononuclear cells were isolated by Ficoll-Paque (GE Healthcare Life Sciences) density gradient centrifugation. Cells were cultured in the serum-free medium StemSpan SFEM (referred to as SFEM) purchased from Stem Cell Technologies and supplemented with recombinant human stem cell factor (SCF, 100 ng/ml), interleukin-3 (IL-3, 20 ng/ml), FMS-like tyrosine kinase ligand (FLT3L, 100 ng/ml), granulocyte colony-stimulating factor (G-CSF, 20 ng/ml) and granulocyte-macrophage colony-stimulating factor (GM-CSF, 20 ng/ml) (Shenandoah Biotechnology). All cultures were incubated at 37°C with 5% CO2. Informed consent was obtained from all patients under Penn State College of Medicine Institutional Review Board-approved protocol according to the Declaration of Helsinki.

HEK 293T, U937, K562 and THP-1 cells were obtained from the American Type Culture Collection (ATCC) and the German Collection of Microorganisms and Cell Cultures (DSMZ). De-identified patient samples were provided by Loma Linda University (Loma Linda, CA, USA) and collaborators at the Penn State Cancer Institute in compliance with institutional review board regulations. Cells were cultured with RPMI 1640 plus (Mediatech, Manassas, VA, USA) with a 10% heat-inactivated Fetal bovine serum (FBS) (HyClone, Rockford, IL, USA) and 1% penicillin-streptomycin. HEK-293T cells were cultured in DMEM (CellGro) supplemented with 10% FBS. Human AML primary cells (AML-1), previously expanded in mice, were cultured in StemSpan SFEM (Stem Cell Technologies, Cambridge, MA, USA), supplemented with a recombinant human stem cell factor (SCF, 100 ng/mL), IL3 (20 ng/mL), FMS-like tyrosine kinase ligand (FLT3L, 100 ng/mL), G-CSF (20 ng/mL), and GM-CSF (20 ng/mL; Shenandoah Biotechnology, Warwick, PA), as well as 1% penicillin-streptomycin.

Long-term G-CSF Exposure in Breast and Colon Cancer

Check if the same lab product or an alternative is used in the 5 most similar protocols
Mouse breast cancer cell (4T1) and colon cancer cell (CT26) were purchased from ATCC (Manassas, VA, USA) and cultured in RPMI-1640 complete medium containing 10% fetal bovine serum (Thermo Fisher Scientific, Waltham, MA, USA). Both cell lines were cultivated with 5% at 37 °C CO2 in a humidified atmosphere and treated with G-CSF (Shenandoah Biotechnology, Warwick, PA) for either 10 days (short term) or 7 weeks (long term) at 25 ng/ml. Our previous study 20 (link) showed that the cytokine expressions after 6 weeks treatment of G-CSF were significantly different with short term groups. So we selected 7 weeks treatment in this study. Cells treated with PBS were used as the control group. Supernatants of long-term culture were saved for cytokine analysis and cell pellets were saved from RNA extraction.

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.
