Nod scid gamma mice

Manufactured by Jackson ImmunoResearch
Sourced in United States, Montenegro

NOD scid gamma (NSG) mice are an immunodeficient mouse model developed by Jackson ImmunoResearch. These mice lack mature T cells, B cells, and natural killer cells, making them a valuable tool for research involving human cell and tissue transplantation.

NOD scid gamma mice were obtained from The Jackson Laboratory. All mice used in the study were 6 weeks of age. Mouse care followed the guidelines of the Animal Care Committee of the Korea Research Institute of Bioscience and Biotechnology. The Dsg2-positive or -negative cells were dissociated using Accutase and the pellets were suspended in 1:1 (v/v) DMEM/F12 and Matrigel. Approximately 1 cm of abdominal skin was incised with fine scissors under isoflurane inhalation anesthesia. The testes were removed from the abdominal cavity using sterilized forceps, and cells were injected into each side of the testes using a 31-gauge Ultra-Fine syringe. See Supplemental Experimental Procedures for additional experimental information and further procedures.

Lung Colonization Assay in Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
Seven- to twelve-week-old age-matched NOD/SCID gamma mice (Jackson Labs) were used for lung colonization assays. Male mice were used for assays with H1299 cells, and female mice were used for assays with H1975 cells. In all cases, 5×104 cancer cells constitutively expressing luciferase were suspended in 100 μL PBS and then injected via tail-vein. Each cohort contained 4–5 mice. Cancer cell growth was monitored in vivo at the indicated times by retro-orbital injection of 100ul of 15mg/mL luciferin (Perkin Elmer) dissolved in 1X PBS, and then measuring the resulting bioluminescence with an IVIS instrument and Living Image software (Perkin Elmer).

Immunohistochemical Analysis of PDPN in OSCC

Surgical specimens were fixed in 10% formalin in PBS, paraffin embedded, sectioned (4 microns), and processed for hematoxylin/eosin staining and immunohistochemistry with 8.1.1 and D2-40 monoclonal antibodies (Dako) to detect mouse and human PDPN, respectively, as described [61 , 106 (link), 107 (link)]. OSCC cells were cultured in chamber slides (Lab-Tek 177445), fixed in 10% formalin, and processed for immunohistochemistry as described above. For mouse xenograft studies, 1 million HSC-2 cells were injected into the left flank of immunodeficient NOD scid gamma mice (Jackson Labs 005557) and allowed to form tumors which were excised and examined by immunohistochemistry. Human and mouse experimental protocols were approved by the University Institutional Review Board (study ID Pro2012001544) and Institutional Animal Care and Use Committee (APR 10579), respectively.

The animal studies and procedures were approved by the Association for Assessment and Accreditation of Laboratory Animal Care-accredited Institutional Animal Care and Use Committees of Veteran’s Administration Pittsburgh Health System. Seven-week-old male NOD/SCID gamma mice (Jackson Laboratory) were anesthetized with ketamine/xylazine. Long-acting buprenorphine was used as pain reliever. Sterile surgery was performed to expose the spleen. Half a million of cancer cells were injected into the spleen using 27-gauge needle. Running stitch with absorbable suture was performed to close the omentum and metal wound clips were used to close the skin wound. Mice were sacrificed after 5 weeks using a carbon dioxide chamber according to AVMA Guidelines on Euthanasia.

In Vivo Combination Treatment of cAC10-vcE and Everolimus in B-Like Hodgkin Lymphoma

To test combination treatments in B-like Hodgkin lymphoma in vivo, a murine xenograft model was used. L428 cells were implanted into NOD-SCID-gamma mice (The Jackson Laboratory) to generate tumors. Tumors were grown to an average of 90 mm3, then sorted into groups of 10 mice. Mice were not treated, treated with everolimus (15 mg/kg), treated with cAC10 (1 mg/kg), treated with cAC10-vcE (1.0 mg/kg), treated with cAC10 and everolimus, or treated with cAC10-vcE and everolimus. The cAC10-vcE and cAC10 was administered q4d×4 ip. The everolimus was administered q1d×14 po. At day 61, the cAC10-vcE and everolimus combination treatment arm has 10/10 complete responses and the cAC10-vcE and everolimus single treatment arms had no complete responses.

Xenograft Mouse Model for Tumor Growth

Check if the same lab product or an alternative is used in the 5 most similar protocols
All animal work was performed in accordance with protocols approved by the University of Cincinnati Standing Committees on Animals. Female nude CD-1 mice (Charles River) (A549 cell line), NOD/SCID-gamma mice (Jackson Lab) (LAM 621-101 cell line), and CB17-scid mice (Taconic) (RT4 and ELT3-luciferase cell lines), 6 to 8 weeks of age, were used. 2×106 cells were subcutaneously inoculated into the posterior back regions of each mouse. Once the tumor is formed three to five weeks post inoculation, tumor length and width were measured using a digital caliper. Tumor volume was calculated using the formula: volume = (length × (width)2/2). For the drug treatment experiment, mice were randomized into two groups after tumor formation and treated with either vehicle control (100 µl of 1% DMSO in PBS) or SRPIN340 (100 µl of 20 µg/ml; 1% DMSO in PBS) by daily peritumoral injection as previously described (Gammons et al., 2014 (link)). SRPIN340 was dissolved as 2 mg/ml in DMSO, and this stock solution was diluted 1:1,000 using PBS prior to inject. For the bioluminescent imaging of ELT3-luciferase tumors, luciferin (120 mg/kg, Xenogen) was intraperitoneally injected into the mouse 10 min prior to imaging. Bioluminescent signals were recorded using the Xenogen IVIS System and the total photon flux of tumors was analyzed as previously described (Yu et al., 2009 (link)).

Evaluating Anti-Tumor Effects of Cuc D

Check if the same lab product or an alternative is used in the 5 most similar protocols
We performed ectopic xenograft studies in mice to determine the anti-tumor effect of Cuc D. To this end, six-week old NOD-SCID gamma mice were purchased from Jackson laboratory and maintained in a pathogen-free environment. All of the procedures were carried out in accordance with the protocol that the UTHSC Institutional Animal Care and Use Committee (UTHSC-IACUC) approved. HPAF-II cells (4 × 106 cells) were suspended in phosphate buffer saline (PBS) and Matrigel (BD Biosciences) solution (1:1 ratio) and subcutaneously injected on the dorsal flanks of each mouse to establish ectopic xenograft tumors in mice. Mice tumor growth was monitored while using a digital Vernier caliper. When tumor volume reached ~100 mm3, mice were divided into control groups and Cuc D treatment groups. The mice were treated with Cuc D (1 mg/kg bwt thrice a week; intra-peritoneally) or vehicle control (PBS). Tumor volumes were measured weekly and then calculated while using formula 0.5238 × L × W × H, where L is length, W is width, and H is tumor height. Mice were euthanized when the control mice tumor volume reached ~1000 mm3. The tumors were excised and processed for RNA, tissue lysates, histopathology, and preparation of slides (5μm section) at the time of sacrifice.

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.
