All of the in vitro analyses were performed in an experimental model using a commercially available monocyte/macrophage peripheral blood cell line—SC (ATCC CRL-9855) (ATCC; Manassas, VA, USA). Cell cultures were kept under standard conditions (37 °C; 5% pCO2; 95% humidity) according to the guidelines provided by the manufacturer. Cells were cultured in Iscove’s Modified Dulbecco’s Medium (IMDM) with 4-mML-glutamine adjusted to contain 1.5 g/L sodium bicarbonate (ATCC; Manassas, VA, USA) and supplemented with 0.05-mM 2-mercaptoethanol (Sigma-Aldrich Corp., St. Louis, MO, USA), 0.1-mM hypoxanthine and 0.016-mM thymidine (90%) (ATCC; Manassas, VA, USA), fetal bovine serum (10%) (ATCC; Manassas, VA, USA) and 1% penicillin/streptomycin solution (P/S) (ScienCell Research Laboratories, San Diego ad, CA, USA). Each cell culture was split when it reached 90–95% confluency. All of the tested cements were mixed according to manufacturer’s instructions and then cured in sterile hemi-sphere molds, r = 3.75 mm (surface area 1.33 cm2, volume of 140 μL). Immediately after reaching the setting time as provided by the manufacturer, the specimens were placed in Eppendorf tubes containing 1 mL of cell culture medium and were incubated for 24 and 48 h at 37 °C. The eluates were centrifugated for 5 min (2000 rpm) and then used for further analysis [33 (link)].

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.
