Murine Model of Peri-Implant Disease

Eighteen four-week-old C57BL/6J (The Jackson Laboratories, Bar Harbor, ME) male
mice were used according to the guidelines of the Chancellor's Animal Research
Committee of the University of California, Los Angeles. In addition, the ARRIVE (Animal
Research: Reporting In Vivo Experiments) guidelines for the execution and submission of
studies in animals were followed (20 (link)). Mice were
fed a soft diet (Bio Serve®, Frenchtown, NJ) ad libitum for the
duration of the experiment. Eight animals/implants were included in the control group and
10 animals/implants in the experimental group (ligature, peri-implantitis). At the end of
the experimental period, there were eight remaining implants in the control group and six
in the experimental group. No other adverse events were observed in the animals other than
loss of implant osseointegration. All the procedures performed in the mice including tooth
extraction, implant placement and ligature placement were performed under 10×
magnification (Leica S6D Stereozoom, Chicago, IL).

Explant Culture Regulation by CUL3 Silencing

Check if the same lab product or an alternative is used in the 5 most similar protocols
Explant culture was performed as described previously (Genbacev et al. 1992) (link). In brief, placental anchoring villi (5-8 w) were identified by a phase contrast microscope (Leica S6 D Stereozoom; Leica, Heerbrugg, Switzerland), dissected, and placed on the Millicell-CM culture plate inserts (EMD Millipore Corp.) pre-coated with phenol red-free and growth factor-reduced Matrigel (Becton Dickinson, Bedford, MA, USA). The inserts were then placed into a 24-well culture plate (Costar, Cambridge, MA, USA). The explants were cultured in serum-free DMEM mixed 1:1 with Ham's F-12 (DMEM/F12; HyClone) medium with 500 nM of scrambled control siRNA or CUL3 siRNA (5 0 -AUAACUUGUACAUG-CAACCAAGGUC-3 0 ). Explants were photographed daily for up to 4 days. The distance from the cell column base to the tip of the outgrowth was measured with SPOT Imaging Software (SPOT Imaging Solutions, Diagnostic Instruments, Inc., Sterling Heights, MI, USA). All the explant experiments were repeated three times and replicated in four separate sets of explants.

Floating Villi Culture for Early Placentation

Check if the same lab product or an alternative is used in the 5 most similar protocols
Floating villi at 6-10 weeks of gestation were dissected under a phase-contrast microscope (Leica S6 D Stereozoom). Small pieces (0.5×0.5 cm) of decidua with no anchored villi from the same individual were also collected and mounted onto transwell inserts (Millicell Cell Culture Inserts, 0.4 µm, 12 mm diameter, PICM01250, Merck Millipore) containing matrigel (5 mg/ml). Counterparts from the same decidua were used for immunofluorescence to examine whether trophoblast cells are present or not. After the decidua was well mounted on the matrigel, three to eight floating villous trees without columns were explanted to the upper surface of the mounted decidua. The co-cultured tissues were fixed with 4% PFA after being cultured for 3 days.

Induction of Experimental Periodontitis in Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
A modified mouse model of ligature-induced experimental periodontitis was generated based on method previously described.1 Six WT mice and 8 TLR9 KO mice were randomly selected for each group. On day 0, the silk thread of size 7-0 (Fisher Scientific) were ligated around both maxillary second molars in each mouse and remained for 2 weeks. The palatal gingiva on the left side was injected with a CpG+CD40L mixture (0.1 μg/ml of CD40L + 40 μM CpG) and that on the right side was injected with vehicle control (PBS). Insulin syringes (Gauge 31, 3/10cc, BD Biosciences) were used for the injection. To perform the injection accurately, the tip of each needle was blunted to ensure that its tip was embedded in the gingiva during the procedure. On days 3, 6, and 9, CD40L+CpG or PBS was injected into the palatal gingiva of maxillary second molars of each mouse. We performed the whole procedures of ligature and injection using an optical microscope (S6D Stereozoom, Leica).

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.
