US Patent 7875260 Imaging agents for functional imaging of lymphatic structures

Novel imaging agents targeted to a lymph vascular cell receptor and a hyaluranon cell receptor are disclosed. The disclosed imaging agents incorporate biological molecules such as hyaluronic acid which bind to the receptors. Lymph vascular cell receptor expression may be related to the beginnings of tumor formation. As such, embodiments of the imaging agents may be used to stain lymph structures for detailed imaging of lymph architecture as well as serving as potential markers for tumor angiogenesis, tumor metastases, etc.
