The extracellular matrix (ECM) is a network of molecules that provide a structural framework for cells and tissues and helps facilitate intercellular communication. Three-dimensional cell culture techniques have been developed to more accurately model this extracellular environment for in vitro study. While many cell processes during migration through 3D matrices are similar to those required for movement across rigid 2D surfaces, including adherence, migration through ECM also requires cells...

Minimally invasive surgical (MIS) procedures rely on anatomical references to localize structures not directly visible to the surgeon. This manuscript describes a combined method of plane-by-plane dissection and sectional anatomy of fresh-frozen specimens to locate the structures at risk during MIS procedures.
FAQs
Successful invasion depends on coordinated changes rather than movement alone. Invading cells modify their adhesion to surrounding structures, allowing them to interact with neighboring tissue as they respond to chemical and mechanical cues. These interactions help determine where cells travel and how local tissue organization changes during development, repair, or disease progression.
Extracellular matrix remodeling can occur through two described routes: cells may exert force on the matrix, or they may release enzymes that degrade it. These mechanisms address the physical barrier differently, but both can alter the path available to migrating cells. Distinguishing them helps researchers interpret how tissue boundaries change during normal processes and pathological infiltration.
Tissue invasion can serve normal biological functions or contribute to disease. During embryonic development, it helps cells form organs, while immune-cell movement supports access to injury sites. In cancer, cells may breach tissue boundaries and spread. Comparing these contexts helps researchers distinguish invasion that supports organization and repair from invasion associated with pathological progression.
Researchers study tissue invasion with imaging, culture systems, and animal models. These approaches reveal cellular interactions that control movement through neighboring tissue and show how invasion reshapes local organization. Using these tools, investigators can examine the same biological theme in contexts that include embryonic organ formation, immune access to injury, and cancer-associated tissue breach, linking observed behavior to broader biological significance.
In cancer research, invasion studies focus on how cells breach tissue boundaries and spread beyond their original surroundings. They also examine the interactions that enable pathological tissue infiltration, including altered adhesion, cue-guided movement, and extracellular matrix remodeling. These observations connect cellular behavior with disease progression and may identify processes worth targeting when the goal is to limit harmful spread.
Studies of tissue invasion can guide strategies to limit pathological tissue infiltration by identifying the cellular interactions that control it. This research links changes in adhesion, responses to chemical or mechanical cues, and extracellular matrix remodeling with movement through tissue. Such knowledge is relevant when invasion contributes to cancer progression or other disease-related disruption of local organization.
