Chorioallantoic membrane vascularization. A meta-analysis
Experimental Cell Research, 2021The CAM is a widely used experimental assay to study angiogenesis, wound healing, tumor growth and metastatic process. In this study, we have analyzed and compared the existent literature data concerning the growth of the CAM. Moreover, we have analyzed the data concerning the development of the vascular system and the expression of the most important ...

The gelatin sponge–chorioallantoic membrane assay
Nature Protocols, 2006Here we present a method for the quantification of angiogenesis and antiangiogenesis in the chick embryo chorioallantoic membrane (CAM) based on the implantation of a gelatin sponge on the top of the growing CAM on day 8 of development. After implantation, the sponge is treated with a stimulator of blood vessel formation in the absence or presence of ...

The chorioallantoic membrane in irritation testing
Food and Chemical Toxicology, 1986The chorioallantoic membrane (CAM) of the chick embryo is a fusion membrane with a blood vessel complex. It was examined as a possible means of predicting the irritant potential of chemicals for the conjunctiva, as observed in the Draize eye test. Nine chemicals of known irritancy potential for the eye in vivo were selected from published data, and ...

Liver Regeneration on Chicken Chorioallantoic Membrane
Cells Tissues Organs, 2001To explore how the liver regenerates, liver pieces from 15-day-old chicken embryos were grafted onto the chorioallantoic membrane (CAM) of 9-day-old chicken embryos and cultured for 11 days at the longest. The cultured liver pieces were examined histologically.

Chorioallantoic membrane heterotransplantation of human brain tumors
International Journal of Cancer, 1975AbstractSpecimens of human tumors were taken from the operating room and directly heterotransplanted to chick chorioallantoic membranes. Seventy‐one percent of the eggs survived the procedure and 41% of the tumors appeared viable after 1 week. Micro scopically, the first‐generation heterotransplants resembled the parent tumors.

Angiogenesis Assays Using Chick Chorioallantoic Membrane
2003The study of the angiogenic process and the search for novel therapeutic agents to inhibit, or stimulate, angiogenesis has employed a wide range of in vivo 'angiogenesis' assays (reviewed in 1-3). These differ greatly in their difficulty, quantitative nature, rapidity, and cost. The classical in vivo models include the rabbit ear chamber, hamster cheek

Etiology of Keratogenic Metaplasia in the Chorioallantoic Membrane
Science, 1959The effects of elevated O 2 and CO 2 concentrations on the occurrence of experimental keratogenic metaplasia in the chorion of the chick embryo were examined. Exposure to oxygen resulted in advanced keratinization of the chorion; carbon dioxide at elevated concentrations, in mixtures with air

Quantitative Assays for the Chick Chorioallantoic Membrane
2000Focal application of angiogenic substances to the chick chorioallantoic membrane is quick and easy as a rapid screening test, but is susceptible to artefactual stimulation induced by carriers, hyperosmolarity, proteolytic activity, and indeed any cause of damage to the CAM. This can be deceptive and unanticipated.

Chicken Chorioallantoic Membrane Angiogenesis Model
2011The chick embryo chorioallantoic membrane (CAM) is an extraembryonic membrane which serves as a gas exchange surface and its function is supported by a dense capillary network. Because of its extensive vascularization and easy accessibility, the CAM has been broadly used to study the morphofunctional aspects of the angiogenesis process in vivo and to ...

The chick embryo chorioallantoic membrane (CAM) assay
Reproductive Toxicology, 2017During avian development the mesodermal layers of the allantois and chorion fuse to form the chorioallantoic membrane (CAM). This structure rapidly expands generating a rich vascular network that provides an interface for gas and waste exchange. The CAM allows to study tissue grafts, tumor growth and metastasis, drugs delivery and toxicologic analysis,
