Defining Cardiac Nerve Architecture During Development, Disease, and Regeneration
Biorxiv : the Preprint Server for Biology
|January 30, 2023
Summary
Cardiac nerves are crucial for heart regeneration. In adult mice, regenerating hearts restore nerve connections, unlike non-regenerating ones, offering new therapeutic targets for cardiac repair.
Area of Science:
- Cardiovascular biology
- Neuroscience
- Regenerative medicine
Background:
- Cardiac nerves influence heart regeneration and are altered after injury.
- Existing knowledge of cardiac nerve structure is limited by 2D analysis.
Approach:
- Utilized genetic models, whole-mount imaging, and 3D modeling.
- Defined cardiac nerve architecture and neurovascular associations across development, disease, and regeneration.
Key Points:
- Cardiac nerves develop by associating with coronary vessels.
- Parasympathetic and sympathetic nerves densely and synchronously innervate ventricles.
- Regenerating hearts re-establish physiological cardiac innervation.
Conclusions:
- Reinnervation during cardiac regeneration depends on collateral artery formation.
- Understanding cardiac nerve remodeling offers novel therapeutic strategies for heart disease.

01:15Neurogenesis and Regeneration of Nervous Tissue
941
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

01:19Electrophysiology of Normal Cardiac Rhythm
6.7K
The normal cardiac rhythm is a synchronized electrical activity that facilitates the regular and coordinated contraction of the heart muscle. This process is essential for efficient blood circulation throughout the body. The fundamental elements involved in establishing and maintaining this rhythm include the unique electrical properties of cardiac muscle cells, the sinoatrial (SA) node's pacemaker function, the specialized conducting system, and the ionic mechanisms underlying each phase...

01:30Cardiac Action Potential
2.0K
Cardiac action potentials are essential for proper heart function, enabling the rhythmic contractions needed for adequate blood circulation. Nodal cells and Purkinje fibers, specialized for electrical conduction, generate these action potentials.
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

01:13Structure of Cardiac Muscles
13.7K
Cardiac muscle, or myocardium, is a specialized type of muscle found exclusively in the heart. Its unique structural and functional characteristics enable the heart to perform its vital role of pumping blood throughout the body continuously and rhythmically. The cardiac muscle cells, or cardiomyocytes, possess an endomysium and perimysium but do not have an epimysium.
Compared to skeletal muscles, cardiac muscle cells are small and mostly have a single nucleus. Additionally, they are usually...

01:16Spinal Cord: Cross-sectional Anatomy
2.2K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

01:30Neurulation
42.2K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...
