In molecular biology, ligation refers to the joining of two DNA fragments through the formation of a phosphodiester bond. An enzyme known as a ligase catalyzes the ligation reaction. In the cell, ligases repair single and double strand breaks that occur during DNA replication. In the laboratory, DNA ligase is used during molecular cloning to join DNA fragments of inserts with vectors – carrier DNA molecules that will replicate target fragments in host organisms.

A procedure for making en face preparations of the mouse carotid artery and aorta is described. Such preparations, when immunofluorescently stained with specific antibodies, enable us to study localization of proteins and identification of cell types within the entire vascular wall by confocal microscopy.

This protocol describes an injury model involving the surgical ligation of the pancreatic duct in the adult mouse pancreas, resulting in severe injury that establishes an environment that allows beta cell neogenesis and proliferation. This model can be used as a tool to study mechanisms involved in beta cell formation.

The surgical procedure used to induce experimental myocardial infarction in mice begins with left thoracotomy between the third and the fourth ribs in order to visualize the anterior surface of the heart and left lung. The left coronary artery is ligated, the chest is closed and the mouse is allowed to recover spontaneously.
FAQs
Closing the splenic artery interrupts blood inflow before tissue is divided or manipulated. This reduction in arterial supply limits the amount of blood reaching the operative field and supports hemostasis during procedures involving the spleen. Its effectiveness depends on correctly identifying the intended vessel and securing it without damaging nearby structures.
The splenic vein carries blood away from the spleen, so ligating it prevents normal venous drainage. Blood may therefore accumulate temporarily within splenic tissue, producing congestion while the vessel is closed or surrounding tissues are handled. This differs from arterial ligation, which primarily reduces inflow and limits bleeding reaching the spleen.
Detailed knowledge of splenic vascular anatomy allows the surgeon to isolate the artery, vein, or both as intended. Precise identification helps achieve hemostasis while limiting unintended ischemia and injury to nearby organs. Anatomical accuracy is especially important when operative dissection or vascular handling occurs close to structures adjacent to the spleen.
The surgeon first identifies and isolates the selected splenic vessel. It is then secured with sutures, clips, or another ligature, after which the vessel may be divided or left closed while tissue handling continues. This sequence creates a controlled interruption of blood flow before subsequent operative steps and helps manage bleeding.
Splenic vessel ligation can support splenectomy, treatment of traumatic or operative hemorrhage, and selected pancreatic or vascular procedures. The target vessel depends on the operative objective: arterial closure reduces inflow, venous closure prevents drainage, and closure of both addresses blood movement in both directions. Its role is therefore determined by the surrounding procedure.
Successful ligation provides controlled vascular interruption and supports hemostasis, but the surgeon must also limit unintended ischemia, venous congestion, and injury to nearby organs. These considerations guide vessel selection, anatomical dissection, and the decision to divide the secured vessel or continue tissue handling with it closed.
