The largest database of trusted experimental protocols

The MG-63 is a cell line derived from a human osteosarcoma, a type of bone cancer. It is widely used in cell culture research related to bone and skeletal tissues. The MG-63 cell line exhibits characteristics of osteoblast-like cells and is commonly employed to study bone cell biology, bone tissue engineering, and the evaluation of orthopedic biomaterials.

MNNG/HOS and MG-63cells were bought from Cell Bank of the Chinese Academy of Sciences (Shanghai, China), MNNG/HOS and MG-63 cells were cultured as described previously [19 (link)], and cells were plated in 24-well plate for 24 h before transfection.
Moreover, Lupeol (Sigma-Aldrich, St. Louis, MO, USA) was re-suspended with ethyl alcohol to the concentration of 30 mmol/L mother liquor preparation. It would be diluted in dimethyl sulfoxide (DMSO; Solarbio, Beijing, China) at a 1:1 ratio. The final concentrations were diluted by cell culture medium for preparation.

Four human OS cell lines (SAOS-2, MG-63, U2OS, and HOS) and the normal human osteoblast hFOB1.19 cell line were purchased from the Type Culture Collection of the Chinese Academy of Sciences (Shanghai, China). All these cell lines were incubated at 5% CO2 and 37°C in Dulbecco’s modified Eagle’s medium (DMEM) supplemented with 10% of fetal bovine serum (FBS; both from Gibco, Invitrogen, Carlsbad, CA, USA) and 1% of a penicillin/streptomycin solution (Sigma‐Aldrich, St. Louis, MO).
The synthetic miR-618 mimics and miRNA mimic negative control (miR-NC) were purchased from Guangzhou RiboBio Co., Ltd. (Guangzhou, Guangdong, China). The MTDH-overexpressing plasmid was generated by inserting the MTDH cDNA lacking its 3′-UTR into the pCMV vector. This plasmid was chemically synthesized by Shanghai GenePharma Co., Ltd. (Shanghai, China). The small interfering RNA (siRNA) against MTDH (si-MTDH) was acquired from Qiagen GmbH (Hilden, Germany) and used to knock down endogenous MTDH expression. Negative control siRNA (si-NC) served as a control for si-MTDH. RNA oligonucleotides and the plasmid were transfected into cells using Lipofectamine 2000 (Invitrogen; Thermo Fisher Scientific, Inc., Waltham, MA, USA).

Cell Line Cultivation and Treatment

Check if the same lab product or an alternative is used in the 5 most similar protocols
The cell lines MG-63, Saos-2 and hFOB 1.19 were purchased from the Type Culture Collection of the Chinese Academy of Sciences, Shanghai Institute of Cell Biology, China. The cells were cultured in DMEM (high glucose) supplemented with 10%FBS, 100 units/ml penicillin and 100 mg/ml streptomycin at 37 °C in a humidified atmosphere of 95% air and 5% CO 2 ; for hFOB 1.19 cell culture, 0.3mg/ml G418 was also added, and the cells were cultured at 33.5°C. The cells treated with MLN2238 and DMSO (vehicle) in this study were all first 'starved' for 12h which means after cell adherence, complete medium was replaced with basal medium, followed by treatment with MLN2238 and DMSO dissolved in fresh basal medium. Additionally, the final DMSO concentration of MLN2238 (0-3.20µM) was much less than 0.1%, because the concentration of the stock solution of MLN2238 was 10mM.

Human OS cell lines HOS, U2OS, Saos-2, and MG-63 and normal human osteoblast (NHOst) cell were purchased from the Type Culture Collection of the Chinese Academy of Sciences (Shanghai,China) and maintained in Dulbecco modified Eagle medium (DMEM) supplemented with 10% fetal bovine serum (FBS), 100 U/mL penicillin, and 100 ng/mL streptomycin. All cells were incubated at 37 C in an atmosphere of 5% CO 2 .
Osteosarcoma samples and the adjacent normal samples were collected from clinical patients undergoing OS resection. All these tissues were immediately snap-frozen in liquid nitrogen after surgery. This study was approved by the medical review board, and written informed consent was obtained from all patients.

The MG-63 and U2-OS OS cell lines were purchased from the Type Culture Collection of the Chinese Academy of Sciences, Shanghai Institute of Cell Biology (Shanghai, China). The MG-63 and U2-OS cells were separately cultured in DMEM or McCoy's 5A medium with 10% FBS and 1% penicillin/streptomycin antibiotics. All the cells were maintained at 37°C in a humidified atmosphere of 95% air and 5% CO2. The cells were treated with indicated concentrations of PI-1840 and DMSO (vehicle used as a control; the concentration of DMSO was <0.1%, which would not have affected the physiological status of the OS cells). The concentration of the stock solution of PI-1840 used was 40 mM (in DMSO).

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.
