This systematic approach will facilitate optimal endometriosis management, guide concomitant adnexal surgeries, and enhance post-surgical fertility outcomes. Cancer Research A Permanent Window for Investigating Cancer Metastasis to the Lung Lucia Borriello*1,2, Brian Traub*1,2,3, Anouchka Coste1,2,3, Maja H.

The permanence of the window makes it well-suited to the study of dynamic cellular processes in the lung, especially those that are slowly evolving, such as metastatic progression of disseminated tumor cells. Cancer Research Assessing Tumor Microenvironment of Metastasis Doorway-Mediated Vascular Permeability Associated with Cancer Cell Dissemination using Intravital Imaging and Fixed Tissue Analysis George S.

The methods include intravital imaging in live animals and fixed tissue analysis using immunofluorescence.
