We describe two methods for assessing transient vascular permeability associated with tumor microenvironment of metastasis (TMEM) doorway function and cancer cell intravasation using intravenous injection of high-molecular weight (155 kDa) dextran in mice. The methods include intravital imaging in live animals and fixed tissue analysis using immunofluorescence.
This protocol presents techniques to laparoscopically excise ovarian endometrioma, to perform adhesiolysis with sparing electrosurgical application, and to employ intraoperative chromopertubation to assess for genital tract patency. This systematic approach will facilitate optimal endometriosis management, guide concomitant adnexal surgeries, and enhance post-surgical fertility outcomes.
