Insights

Pericytes, crucial perivascular cells, are identified as key precursors to myofibroblasts. This finding is vital for understanding and treating tissue fibrosis, a widespread disease with limited therapies.

Area of Science:

  • Cell Biology
  • Tissue Engineering
  • Pathology

Background:

  • Fibrotic diseases pose a significant global health challenge with few effective treatments.
  • Myofibroblasts are central to fibrosis due to their role in extracellular matrix deposition.
  • Understanding myofibroblast origins is critical for developing anti-fibrotic therapies.

Purpose of the Study:

  • To investigate the cellular origins of myofibroblasts, particularly in the context of tissue fibrosis.
  • To highlight the role of pericytes as potential precursors to fibrogenic myofibroblasts.

Main Methods:

  • Utilizing genetic fate-mapping strategies to trace cell lineages.
  • Permanent and heritable expression of reporter proteins in specific cell populations.

Main Results:

  • Recent studies across multiple organs indicate pericytes are a significant source of myofibroblasts.
  • Fate-mapping data supports pericytes as direct precursors in fibrotic processes.

Conclusions:

  • Pericytes play a central role in the development of fibrosis.
  • Targeting pericyte differentiation may offer novel therapeutic strategies for fibrotic diseases.

Introduction to Fibroblasts01:09

Introduction to Fibroblasts

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...
Cirrhosis II: Pathophysiology01:24

Cirrhosis II: Pathophysiology

Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
Liver Regeneration01:24

Liver Regeneration

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 large...
Cell Migration01:19

Cell Migration

Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Fibronectins Connect Cells with ECM

Fibronectin is an adhesive glycoprotein present in the extracellular matrix of embryogenic and adult tissue. These molecules primarily aid in regulating cell motility and attachment. A fibronectin molecule is composed of two identical polypeptide chains attached to each other by a pair of disulfide bonds at the C-terminal.
Both proteoglycans and collagen are attached to fibronectin proteins, which, in turn, are attached to integrin proteins. These integrin proteins interact with transmembrane...
