Development of the Heart01:27

Development of the Heart

3.9K
The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart...

General Transcription Factors

5.9K
Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Anatomy of the Heart01:20

Anatomy of the Heart

6.0K
The heart is a hollow, muscular organ approximately the size of a fist, consisting of four chambers. It is enclosed in the pericardium, a fibrous sac with two layers: the visceral and parietal pericardium, separated by a fluid-filled space containing serous fluid to reduce friction.
The heart has three layers: the innermost endocardium, the muscular myocardium, and the outer epicardium, all working together for optimal cardiac function.
Chambers of the Heart
The heart is made up of four...

Anatomy of the Heart

93.3K
The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

Summary
This summary is machine-generated.

Congenital heart defects (CHD), like Tetralogy of Fallot (TOF), impact infant mortality. Gene expression templates (GET) reveal cardiac developmental disturbances in TOF, maintaining homeostasis within the heart.

Area of Science:

  • Developmental Biology
  • Genomics
  • Cardiovascular Science

Background:

  • Congenital heart defects (CHD) are the leading cause of infant mortality.
  • Tetralogy of Fallot (TOF) is a severe CHD linked to conotruncal outflow tract developmental errors.
  • A tissue-specific gene expression template (GET) has been established for characterizing human tissues.

Purpose of the Study:

  • To apply the GET to analyze spatial, temporal, and pathological variations within the heart.
  • To investigate how GET reflects normal cardiac development and the impact of TOF.
  • To assess the maintenance of homeostatic equilibrium at the intra-organ level.

Main Methods:

  • Utilized microarray data to define a gene expression template (GET).
  • Applied the GET to cardiac tissue samples, examining normal and pathological (TOF) states.
  • Analyzed spatial and temporal differences in cardiac gene expression using the GET.

Main Results:

  • The GET successfully identified temporal and spatial variations in cardiac tissue.
  • Stoichiometric differences in the GET correlated with the severe developmental disturbance in TOF.
  • Cardiac gene expression patterns indicated maintained homeostatic equilibrium within the heart.

Conclusions:

  • The gene expression template (GET) is a valuable tool for studying cardiac development and pathology.
  • GET analysis reveals significant developmental disturbances in Tetralogy of Fallot.
  • Homeostatic equilibrium is generally maintained at the intra-organ level within the heart, even in severe CHD.
