intraperitoneal injection in humans

Zhang, B. et al. In this study, three different MSCs delivery routes, intraperitoneal injection (IP), intravenous injection (IV) and anal injection (AI) were compared on DSS-induced colitis mouse model. 17 The influence of the sex of the animal on anesthetic agents remains poorly researched and understood. Blood 122, e23e32, doi: 10.1182/blood-2013-04-495119 (2013). In colonic MLNs, similar results were observed, the MSCs administration induced more FoxP3+ cells accumulation than the control, but the inter-group differences were not evident (Supplementary Figure S8). Intraperitoneal (ml) Footpad (ml) Mouse <0.1 . Epub 2020 Mar 18. 2010 May;27(5):735-8. doi: 10.1007/s11095-009-0031-z. Bioengineered. Human mesenchymal stem cells license adult CD34+ hemopoietic progenitor cells to differentiate into regulatory dendritic cells through activation of the Notch pathway. Mice were sacrificed and colons were collected for histological analysis. Clinical and experimental immunology 116, 238245 (1999). Blood 109, 46274634, doi: 10.1182/blood-2006-12-064345 (2007). In DSS control FoxP3 positive cells only accounted for 1.51% of total cells, while the IP group showed 13.5% positive cells (P<0.001). The measurement of inflamed colon length demonstrated therapeutic effects of MSCs injection. IP injections are used for a variety of reasons: The peritoneum provides a large surface area for absorption of drug (compared with intramuscular (IM) or subcutaneous); can thus inject a larger fluid volume. When searching "intraperitoneal injections" a majority of the results relate to the use of IP injections in murine or rat models in order to study the effect of some drug or chemical. & Gratwohl, A. Journal of immunology (Baltimore, Md. In patients with peritoneal surface malignancies, perioperative IP chemotherapy has been used with good results. Yu-Lung Chang, Huei-Yu Lo, Chin-Kan Chan, Xing-hua Pan, Qing-qing Li, Guang-ping Ruan, Hongsheng Yang, Rui Feng, Shenghong Zhang, H. R. Wardill, C. E. M. de Mooij, N. M. A. Blijlevens, Suze A. Jansen, Edward E. S. Nieuwenhuis, Caroline A. Lindemans, Scientific Reports Here, we combined the iDISCO + method and Fos immunostaining to confirm that the middle part of the right-side, but not the left-side, insular cortex in adult male mice is activated by intraperitoneal injection of lithium chloride. Though genetic and environmental factors are believed to be involved in the disease, not much progress has been made on therapy. [2] Intraperitoneal injections can be similar to oral administration in that hepatic metabolism could occur in both. MSCs organ distribution and engraftment was analyzed and quantified by GFP+ MSCs as well as Near-infrared fluorescence imaging. IP injected human MSC rapidly formed aggregates with mouse macrophages and B220+ lymphocytes and attached to the walls of the peritoneal cavity. Human bronchial epithelial cells (BEAS-2B and 16HBE) were purchased from Shanghai Zhongqiao Xinzhou Biological Co., Ltd, and cultured in a complete medium supplemented with growth factors and .1% penicillin-streptomycin. In addition, fewer female mice achieved surgical anesthesia, suggesting a narrow therapeutic window for intraperitoneal KX in female mice. These findings may benefit clinic practice. The data showed that the TSG-6 levels increased with time in both IP and IV injection groups, while in DSS control group, the TSG-6 level decreased from 48h to 72h. Although there is no significant difference among three injection groups at 48h after MSCs transplantation, the serum TSG-6 was significant higher in IP injection group compared with naive group (P=0.024). To varying degrees, all the three MSCs delivery ways could ameliorate DSS-induced colitis. Cytokine in colonic protein extracts were determined by ELISA Kits according to the manufacturers instructions (R&D Systems, Minneapolis, MN). MSCs have been well characterized regarding their ability to produce a range of cell cytokines, which have a profound effect on modulating the immune system. Google Scholar. In IV group, the colon homing cells were fewer, most of MSCs were trapped in MSCs were rapidly accumulate into the lung and mononuclear phagocytic system. mRNA-engineered mesenchymal stem cells for targeted delivery of interleukin-10 to sites of inflammation. Google Scholar. study on peritoneal cells (PCs) migration to gut may give us some hints27. ADS Real time-PCR and ELISA also demonstrate lower TNF- and higher IL-10, TSG-6 levels in IP group. IBD can be painful and persistent for life, which might decrease the quality of life. The primer sequences used were listed in Supplementary Table S1. Am J Gastroenterol 105, 289297, doi: 10.1038/ajg.2009.579 (2010). (B) Quantification of % Ki-67+ cells/crypt, the IP and IA>IV>DSS control, n=6 mice/group; n=3 for the control group. However, more studies described MSCs as hit and run therapy, which discovered most of MSCs died and cleared from the body within 48 to 72h20,41,42,43. Every 1107 cells were incubated with 10mL DiR solution (PBS based containing 3.5g/mL dye and 0.5% ethanol) for 30min at 37C. GFP+ cells were detected at the inflamed colon. 81421003 and No. Intraperitoneal injections are typically made in the lower right or left quadrant of the hamster's abdomen, not on the midline. Complications associated with intraperitoneal chemotherapy catheters. However, is IV injection the best way for MSCs delivery in IBD? injections. (A) The colonic mRNA expression of TNF- and IL-10 was analyzed by RT-PCR; (B) cytokine contents in colonic protein extracts were determined by ELISA; n=6 mice/group; n=3 for the control group (C) Serum TSG-6 level in different groups measured by ELISA. It can significant reduce failure puncture and associated organ damages caused by blind needle puncturing. Lipids were . . Tuning the Physicochemical Characteristics of Particle-Based Carriers for Intraperitoneal Local Chemotherapy. (CS), Intraperitoneal, Polymicrobial, and Antibiotics available under aCC-BY 4.0 International license. The IP and AI groups showed mean 50.4% and 46.7% Ki-67+ cells/crypt respectively. Adv Exp Med Biol 371A, 6165 (1995). National Library of Medicine The bilateral femurs and tibias were aseptically excised, stripped of connective tissues and then stored in PBS. More recently the IP route has been used for chemotherapy in patients with intra-abdominal malignancies, i.e. (A) Representative IHC images of each MSCs treatment group. Disease recovery was evaluated by histological server score, gross body weight and survival rate. Figure 1. Exposure to BHT through inhalation, dermal, and oral routes is harmful. Qualitatively, the existence of non-portal drainage was demonstrated by . Human CD3 + T cells were weakly detected during the first 2 to 3 weeks after intraperitoneal injection of human PBMCs; however, 4 weeks after intraperitoneal injection, the percentage of human CD3 + T cells rapidly increased, reaching peak levels of 79.1%. Use of lipophilic near-infrared dye in whole-body optical imaging of hematopoietic cell homing. Background. Insular cortex is a critical brain region that participates in the interoceptive sensations. Collagen Deposition was assessed with phosphomolibidic acid-picrosirius red staining. Cells, tissues, organs 169, 1220 (2001). Karp, J. M. & Leng Teo, G. S. Mesenchymal stem cell homing: the devil is in the details. Cosnes, J., Gower-Rousseau, C., Seksik, P. & Cortot, A. some potent chemo and radio-labeled drugs)59. Intraperitoneal foreign bodies such as suture material, clips, and mesh also contribute to adhesion formation. Another study by coating MSCs with VCAM-1 also exhibited an increased MSCs migration to the inflamed colon and promoted tissue repair capacity25. In addition, MSCs showed inhibitory effects on proliferation of memory T-cells by direct cell contact52. [17] Contrast agents were administered intraperitoneally instead of intravenously to avoid errors and challenges. This concern arises because MSCs has an estimated diameter of 2030m15,16. MeSH Intra-abdominal adhesions can be a considerable source of morbidity and mortality. This inconsistency may attributed to different MSCs types. FoxP3+ cells were greatly increased in MSCs therapy. In contrast, GFP+ cells were showed in the lumen for AI group and lamina propria for IV group (Fig. Since that time, the literatures using stem cells for IBD have expanded. In study by Pennesi et al., MSCs was found to be able to prevent damages caused by collagen-induced arthritis, despite of lack of a detectable presence in the arthritic joint45. MSCs were isolated from C57BL/6 mice bone marrow as previously reported62. Horwitz, E. M. et al. (A) Scheme of the treatment, the day of MSCs injection was defined as day 0. Choi, H., Lee, R. H., Bazhanov, N., Oh, J. Y. and JavaScript. After 3 passages, spindle-shaped cell colonies gradually predominate in the cultures. Small animals: 1 mL per 10 lb of body weight. The supernatants were diluted 1:30 with assay buffer consisting in 50mM phosphate buffer pH 6.0 with 0.167mg/mL o-dianisidine (Sigma) and 0.0005% H2O2.The colorimetric reaction was measured at 450nm between 1 and 3min in a spectrophotometer (Varioskan Flash Multimode Reader, Waltham, MA). PloS one 7, e33360, doi: 10.1371/journal.pone.0033360 (2012). [citation needed]. The study overall defines appropriate doses and toxicity levels of dl1520 when injected intraperitoneally. During the observation, the body weight changes and fecal blood and their survival date was faithfully record. [7] In 1969, errors depending on a variety of techniques of administering IP injections were analyzed, and a 12% error in placement was found when using a one-man procedure versus a 1.2% error when using a two-man procedure. International journal of molecular medicine 37, 115125, doi: 10.3892/ijmm.2015.2413 (2016). Rep. 6, 30696; doi: 10.1038/srep30696 (2016). MSCs induced more Ki-67 positive cells in the lower part of the crypt than the DSS control. Half of the volume of your D-luciferin substrate can be injected on one side of the animal and the other half of the volume on the opposite side. Other than shorten colon, colitis was also characterized by augmented colonic myeloperoxidase (MPO) activity. These findings could be advanced by studying how the route of injection affects the organs in the peritoneal cavity. Stem cell research & therapy 6, 55, doi: 10.1186/s13287-015-0066-5 (2015). Near-infrared imaging and quantification of MSCs transplants. von Bahr, L. et al. Two patients with long-standing ulcerative colitis, psoriasis and leukemia underwent allogeneic stem cell transplantation and all the three disorders were in clinical remission for 4 years after transplantation11. In this study, we compared therapeutic efficacy of three MSCs administration routes in DSS-induced colitis. In humans, numerous plasma molecules prevent or modulate cell stimulation by microbial products, either by neutralizing the agonists (eg, bactericidal permeabilityincreasing protein, .
