Human bm mscs

Sourced in United States

Human BM-MSCs are primary mesenchymal stem cells derived from human bone marrow. They are characterized by their ability to differentiate into various cell types, including osteoblasts, chondrocytes, and adipocytes. The cells are cryopreserved and available for research and development purposes.

Neuroblastoma and BM-MSCs Culture

Check if the same lab product or an alternative is used in the 5 most similar protocols
The neuroblastoma cell line BE(2)‐C was purchased from the American Type Culture Collection (ATCC; Manassas, VA, USA) and cultured in DMEM and Ham's F‐12 (DMEM/F‐12; Wako, Osaka, Japan) supplemented with 10% FBS. We purchased human BM‐MSCs from the ATCC and maintained them in low‐glucose DMEM (Wako) supplemented with 10% FBS.
Recombinant human CXCL1 and CXCL2 were obtained from R&D Systems (Minneapolis, MN, USA; 275‐GR and 276‐GB). A CXCR2‐specific antibody for neutralization was purchased from Abcam (ab10401; Cambridge, MA, USA).

3D Bioprinting of BM-MSCs in Silk-Collagen

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human BM-MSCs (ATCC, VA) were expanded following the manufacturer's instructions. Expanded BM-MSCs were trypsinized and resuspended in culture media (1 • 10 6 cells/mL) and mixed with the collagen control, 50%, and 100% silk-containing collagen pregels before 3D bioprinting (n = 3 for each concentration). Control BM-MSCs were cultured on standard plastic substrate. All experiments were conducted with cells at passages 2-4.

Profiling HCC Tissue-Adjacent Liver

Check if the same lab product or an alternative is used in the 5 most similar protocols
Ninety pairs of primary HCC tissue and adjacent non-tumor liver tissue (> 2 cm and < 5 cm from tumor edge) were collected from patients (56 males and 41 females; age, 41-73 years; mean age, 52.6 years) who underwent surgical resection at our hospital from October 2013 to January 2015. The tissue samples were immediately frozen and preserved at -80 0 C in liquid nitrogen. None of the patients suffered from hepatitis or had previously accepted anti-in ammatory treatment or oncotherapy.
Written informed consent was obtained from all patients before the study and the diagnosis of all tissue samples was made and independently con rmed by two pathologists. Overall survival was calculated during the duration between surgery and death or last follow-up. This study was approved by the Shenzhen Hospital, Peking University Institutional Ethics Committee and conducted following Ethical Principles for Medical Research Involving Human Subjects of the Helsinki Declaration.
Cell culture HCC cell lines (HL7702, HCCLM3, HepG2, and MHCC97-H) and human immortalized hepatocyte line L02, and human BM-MSCs were obtained from the American Type Culture Collection. The cells were all cultured with DMEM containing 10% fetal bovine serum and 1% penicillin-streptomycin.

Culturing Human Bone Marrow Mesenchymal Stem Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human BM-MSCs (American Type Culture Collection, Manassas, VA, USA) were cultured in 175 cm2 cell culture flasks (Corning, Tewksbury, MA, USA) in modified Eagle's medium alpha supplemented with 10% fetal bovine serum (FBS), 100 U/mL penicillin, and 100 μg/mL streptomycin (GIBCO, Carlsbad, CA, USA) at 37°C in a humidified 5% CO2 atmosphere. Upon reaching 70% confluence, cells were dissociated by 0.25% trypsin-EDTA (Invitrogen Carlsbad, CA, USA) and reseeded into 96-well and 12-well plates for the next stage of the experiments.

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.
