Introduction to Fibroblasts

3.9K
Rudolph Virchow discovered spindle-shaped cells called fibroblasts in 1858. Inactive fibroblasts, called fibrocytes, become activated by various stimuli, such as growth factors and inflammatory cytokines. Activated fibroblasts play a crucial role in wound healing, inflammation, formation of new blood vessels, and cancer progression. Uncontrolled activation of fibroblasts results in fibrosis, the excess deposition of fibrous tissue, which can lead to scarring and affect normal organs. This...

Liver Regeneration

4.1K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Area of Science:

  • Biomaterials Science
  • Regenerative Medicine
  • Tissue Engineering

Background:

  • Human decellularized adipose matrix (hDAM) is an off-the-shelf biomaterial for soft tissue augmentation.
  • hDAM offers a biocompatible scaffold promoting angiogenesis, adipogenesis, and volume retention with low immunogenicity.

Purpose of the Study:

  • To systematically review preclinical and clinical evidence on the regenerative potential of hDAM.
  • To evaluate hDAM's capacity for host tissue integration and volume enhancement.
  • To quantitatively analyze the regenerative timeline of hDAM.

Main Methods:

  • Comprehensive literature search across multiple databases for preclinical and clinical studies.
  • Risk of bias assessment using CAMARADES for animal studies and ROBINS-I for human studies.
  • Quantitative analysis of angiogenesis and adipogenesis rates using linear mixed models.

Main Results:

  • Preclinical data shows significant weekly increases in angiogenesis (0.366% CD31+ area/week) and adipogenesis (3.88% perilipin+ area/week).
  • Variability in regeneration rates linked to hDAM preparation methods (e.g., enzyme-free, ultrasonication).
  • Clinical studies demonstrate notable volume retention, patient satisfaction, and improved tissue quality in facial and body contouring.

Conclusions:

  • hDAM is a safe and effective scaffold for soft tissue regeneration, offering advantages over traditional methods.
  • Standardizing hDAM preparation and outcome measures is crucial for optimizing treatment protocols.
  • Further research, including randomized clinical trials and exploration of combination therapies, is warranted.
