Novel and Innovative Hybrid Technique for Type A Aortic Dissection

Novel and Innovative Hybrid Technique for Type A Aortic Dissection

The protocol describes ascending aortic replacement combined with endovascular coverage of the entire aortic arch with a fenestrated stent graft in a patient with acute type A aortic dissection in the absence of a tear in the aortic...

Surgical Porcine Model of Chronic Myocardial Ischemia Treated by Exosome-laden Collagen Patch and Off-pump Coronary Artery Bypass Graft

Surgical Porcine Model of Chronic Myocardial Ischemia Treated by Exosome-laden Collagen Patch and Off-pump Coronary Artery Bypass Graft

This study presents a surgical porcine model of chronic myocardial ischemia due to progressive coronary artery stenosis, resulting in impaired cardiac function without infarction. Following ischemia, animals undergo off-pump coronary artery bypass graft with epicardial placement of stem cells-derived exosomes-laden collagen patch. This adjunctive therapy improves myocardial function and...

Creation of Two Saccular Elastase-Digested Aneurysms with Different Hemodynamics in One Rabbit

Creation of Two Saccular Elastase-Digested Aneurysms with Different Hemodynamics in One Rabbit

This protocol describes the steps for the creation of a rabbit model with two elastase-digested aneurysms with different hemodynamics (stump and bifurcation constellation). This allows the testing of novel endovascular devices in aneurysms with different angioarchitecture and hemodynamic conditions within a single animal.

A Chronic Cardiac Ischemia Model in Swine Using an Ameroid Constrictor

A Chronic Cardiac Ischemia Model in Swine Using an Ameroid Constrictor

The purpose of this protocol is to demonstrate the placement of a delayed constricting device (an ameroid constrictor) around a coronary artery in a swine model. This device creates an ischemic area of the heart that is useful for studying new diagnostic imaging techniques and new methods of treatment.

Direct Re-implantation of Left Coronary Artery into the Aorta in Adults with Anomalous Origin of Left Coronary Artery from the Pulmonary Artery (ALCAPA)

Direct Re-implantation of Left Coronary Artery into the Aorta in Adults with Anomalous Origin of Left Coronary Artery from the Pulmonary Artery (ALCAPA)

Surgical correction of ALCAPA is highly recommended, regardless of age or the degree of intercoronary collateralization. This protocol presents a technique for the direct re-implantation of adult-type ALCAPA into the aorta to re-establish the dual-coronary perfusion. Whenever feasible, direct re-implantation is preferred to other surgical correction...

A New Murine Model of Endovascular Aortic Aneurysm Repair

A New Murine Model of Endovascular Aortic Aneurysm Repair

Histological and biochemical modifications after aneurysm endograft exclusion are still unclear. We describe a new model of endograft implantation on a murine aneurysm. Through thrombus analysis with and without persistant circulating blood stream interface, and new endovascular biomaterials evaluation, this model will help to better understand endovascular aneurysm exclusion...

Area of Science:

Developmental Biology
Cell Biology
Embryology

Background:

Epithelialization is crucial for embryonic development.
Understanding the cellular mechanisms driving epithelialization is essential.
Previous research has not fully elucidated the role of dynamic actin in this process.

Purpose of the Study:

To investigate the role of dynamic actin cytoskeleton rearrangements in epithelialization.
To explore how these actin dynamics influence cell fate determination during mouse embryogenesis.

Main Methods:

Utilized time-lapse imaging techniques.
Observed cellular behaviors in living mouse embryos.
Analyzed actin dynamics at the cellular and subcellular levels.

Main Results:

Demonstrated that dynamic actin movements are integral to the epithelialization process.
Identified specific patterns of actin polymerization and depolymerization.
Correlated actin dynamics with cell shape changes and tissue formation.

Conclusions:

Dynamic actin rearrangements are a fundamental mechanism underlying epithelialization in mammalian embryos.
This study provides novel perspectives on the emergence of cell fates.
Findings open new avenues for research into developmental processes.
