Chicken Chorioallantoic Membrane

Experimental data in this study demonstrate that integrin alpha v beta 3 is fundamentally involved in the maturation of blood vessels during embryonic neovascularization (vasculogenesis). Integrin alpha v beta 3 was specifically expressed on the surface of angioblasts during vessel development in quail embryos and vitronectin, a ligand for alpha v beta 3, localized to the basal surface of these cells. More importantly, microinjection of the anti-alpha v beta 3 monoclonal antibody, LM609, disrupted the normal pattern of vascular development. After exposure to LM609 the angioblasts in experimental embryos appeared as clusters of rounded cells lacking normal cellular protrusions. This led to disruption of lumen formation and abnormal vessel patterning. These findings demonstrate that during vasculogenesis ligation of integrin alpha v beta 3 on the surface of primordial endothelial cells is critical for the differentiation and maturation of blood vessels. Similar studies on chicken chorioallantoic membrane showed that LM609 blocks angiogenesis. Together the two studies suggest that integrin alpha v beta 3 plays a role in neovascularization of tissues.

Phosphorylated Stat3

The JAK-STAT signalling pathway regulates cellular processes like cell division, cell death and immune regulation. Dysregulation has been identified in solid tumours and STAT3 activation is a marker for poor outcome. The aim of this study was to explore potential therapeutic strategies by targeting this pathway in bladder cancer (BC). High STAT3 expression was detected in 51.3% from 149 patient specimens with invasive bladder cancer by immunohistochemistry. Protein expression of JAK, STAT and downstream targets were confirmed in 10 cell lines. Effects of the JAK inhibitors Ruxolitinib and BSK-805, and STAT3/5 inhibitors Stattic, Nifuroxazide and SH-4-54 were analysed by cell viability assays, immunoblotting, apoptosis and cell cycle progression. Treatment with STAT3/5 but not JAK1/2 inhibitors reduced survival, levels of phosphorylated STAT3 and Cyclin-D1 and increased apoptosis. Tumour xenografts, using the chicken chorioallantoic membrane (CAM) model responded to Stattic monotherapy. Combination of Stattic with Cisplatin, Docetaxel, Gemcitabine, Paclitaxel and CDK4/6 inhibitors showed additive effects. The combination of Stattic with the oncolytic adenovirus XVir-N-31 increased viral replication and cell lysis. Our results provide evidence that inhibitors against STAT3/5 are promising as novel mono- and combination therapy in bladder cancer.

Chicken Chorioallantoic Membrane

Glioblastoma is the most malignant tumor in the range of cerebral astrocytic gliomas. A lot of experimental models are used to evaluate various properties of glioblastoma. Chicken chorioallantoic membrane model is one of them. Objective. To evaluate histology and survival of glioblastoma tumors taken immediately from operating theatre and transplanted on chicken chorioallantoic membrane. Materials and methods. Glioblastoma samples obtained from 10 patients were transplanted onto 200 eggs. Overall, we used 15 tumors; only 5 of them were not glioblastomas as it was revealed later. Results. The transplanted tumors survive up to 6 days. Transplants do not survive longer because during embryo’s development the nourishing membrane dries. Transplanted glioblastomas exhibited the same features as original glioblastomas – necrosis, endothelium proliferation, cellular polymorphism – while transplanted glioblastomas also showed glial fibrillary acidic protein (GFAP), vimentin, Ki67, S100 protein, neurofilament immunoreactivity, and infiltration of macrophages (CD68) and T cells (CD3+, CD8+). Transplanted glioblastomas did not show any immunoreactivity of p53. Invasion of vessels from the chicken into transplanted tumor is not observed. Chicken erythrocytes did not appear within the transplants, and tumor cells invade chicken tissue at the minimum. Conclusion. Our data show that transplanted pieces of glioblastoma survive with all cytological features. The presence of macrophages (marker CD68) and T cells (markers CD3+ and CD8+) can be registered in the transplant. The data revealed that transplanted glioblastoma remains as insulated unit, which survives from nourishment of the chorioallantoic membrane apparently only by diffusion. The features of original tumor-host reaction of the patient remained too.
