Systemic application of photosensitizers in the chick chorioallantoic membrane (CAM) model: photodynamic response of CAM vessels and 5-aminolevulinic acid uptake kinetics by transplantable tumors.
The aim of this study is to modify the chick chorioallantoic membrane (CAM) model into a whole-animal tumor model for photodynamic therapy (PDT). By using intraperitoneal (i.p.) photosensitizer injection of the chick embryo, use of the CAM for PDT has been extended to include systemic delivery as well as topical application of photosensitizers. The model has been tested for its capability to mi...
متن کاملThe chick embryo chorioallantoic membrane (CAM). A multifaceted experimental model
During 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, wound healing, drugs delivery and toxicologic analysis, and angiogenic and anti-ang...
متن کاملDosimetry model for photodynamic therapy with topically administered photosensitizers.
BACKGROUND AND OBJECTIVE Photodynamic therapy (PDT) based on topical application of photosensitizers has been under development over the last years. Typical applications are treatment of basal cell carcinoma of the skin and photoablation of the endometrium. The dosimetry for topically administered photosensitizers must take a time-dependent inhomogenous drug distribution into account together w...
متن کاملThe In Ovo Chick Chorioallantoic Membrane (CAM) Assay as an Efficient Xenograft Model of Hepatocellular Carcinoma.
The chick chorioallantoic membrane (CAM) begins to develop by day 7 after fertilization and matures by day 12. The CAM is naturally immunodeficient and highly vascularized, making it an ideal system for tumor implantation. Furthermore, the CAM contains extracellular matrix proteins such as fibronectin, laminin, collagen, integrin alpha(v)beta3, and MMP-2, making it an attractive model to study ...
متن کاملEvaluating the Effects of Enrofloxacin on Angiogenesis Using the Chick Embryo Chorioallantoic Membrane Model
Objective- Because little information was available in the literature about the angiogenic property of enrofloxacin, this investigation was undertaken to evaluate this aspect using an in vivomodel. Design- Experimental study. Animals- Twenty fertile chicken eggs (Ross 308) with the average egg-weight of 55 ± 0.4 g were rand...
