The Extracellular Matrix

12.0K
Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...

Dupuytren’s disease (DD) is a fibroproliferative disease of the palm of the hand. Here, we present a protocol to culture resection specimens from DD in a three-dimensional (3D) culture system. Such short-term culture system allows preservation of the 3D structure and molecular properties of the fibrotic...

Extracellular Matrix

5.2K
Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. This extracellular matrix (ECM) is composed of fibrous proteins like collagen, elastin, and fibronectin in a ground substance consisting of interstitial fluid, cell adhesion proteins, and proteoglycans. The proteoglycans form a gel-like material in the spaces between cells and provide hydration, buffering, binding, and force...

Area of Science:

  • Biomedical Engineering
  • Cell Biology
  • Vascular Biology

Background:

  • Understanding tissue vasculature growth is vital for cancer therapy, wound healing, and tissue engineering.
  • Angiogenesis, the formation of new blood vessels, is influenced by mechanical, chemical, and cellular environmental factors.
  • Traditional imaging methods limit the study of dynamic interactions during neovessel development.

Purpose of the Study:

  • To review how time-lapse imaging enhances the understanding of sprouting angiogenesis.
  • To highlight the dynamic interactions between developing blood vessels and their microenvironment.
  • To underscore the potential of advanced imaging in angiogenesis research.

Main Methods:

  • Review of literature focusing on time-lapse imaging techniques in angiogenesis research.
  • Analysis of studies visualizing microvessel growth in 3D space and over time.
  • Examination of environmental factors influencing neovessel development and behavior.

Main Results:

  • Time-lapse imaging allows visualization of microvessel growth dynamics in 3D and over time.
  • Environmental factors, including mechanical forces, proteolysis, growth factors, and stromal cell interactions, dynamically shape angiogenesis.
  • Neovessels actively remodel their microenvironment by degrading matrix, releasing cytokines, and responding to gradients.

Conclusions:

  • Time-lapse imaging provides unprecedented insights into the complex interactions during sprouting angiogenesis.
  • This technology enables detailed characterization of microvessel evolution and environmental responses.
  • Advanced imaging holds significant promise for future research and therapeutic applications in angiogenesis.
