Renal Corpuscle01:20

Renal Corpuscle

6.4K
The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

Development of Blood Vessels01:07

Development of Blood Vessels

1.2K
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

6.4K
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Gastrulation01:56

Gastrulation

64.7K
Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata...

Renal Tubule and Collecting Duct01:24

Renal Tubule and Collecting Duct

2.7K
The renal tubule is divided into three parts: the proximal convoluted tubule (PCT), the Loop of Henle (LOH), and the distal convoluted tubule (DCT).
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...

Determination01:51

Determination

20.4K
During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In...

  • Organogenesis
  • Cell Signaling

Background:

  • Branching morphogenesis is crucial for forming organs like the kidney, lung, and pancreas.
  • Epithelial tubule networks are vital for secretion, excretion, and exchange.
  • Kidney development involves the ureteric bud forming the collecting duct system.

Purpose of the Study:

  • To review advances in understanding ureteric bud patterning in kidney development.
  • To explore shared mechanisms of branching morphogenesis across different organs.

Main Methods:

  • Review of recent scientific literature on branching morphogenesis.
  • Analysis of cell signaling interactions between epithelial and mesenchymal cells.

Main Results:

  • Branching morphogenesis typically involves bud-like anlage elaboration via bifurcation.
  • Interactions between epithelial progenitor cells and mesenchymal cells guide branching.
  • Kidney development features a dynamic signaling relationship between ureteric bud tips and nephron progenitors.
