Introduction to Fibroblasts

3.7K
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...

Skin Diseases and Disorders

5.0K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Chronic Bowel Disorders: Introduction

699
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Skin Cancer

5.6K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Cell Migration01:19

Cell Migration

6.2K
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.

Cell Migration

18.3K
Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

Summary

Keloid formation, a benign skin condition, involves an abnormal response to injury with excessive inflammation and collagen production. Further research is needed to identify the primary cells driving keloid development.

Area of Science:

  • Dermatology
  • Pathophysiology
  • Fibroproliferative Disorders

Background:

  • Keloids are benign dermal growths with no malignant potential, often arising after minor trauma in susceptible individuals.
  • They are characterized by excessive growth beyond wound margins and unclear pathophysiology, with fibroblasts previously implicated.
  • Understanding keloid mechanisms is crucial for developing new treatments.

Purpose of the Study:

  • To review existing literature and update information on the pathophysiology of keloids.

Main Methods:

  • A literature search was conducted using Medline PubMed for relevant publications.
  • Sixty-six publications were retrieved and analyzed for their findings on keloid etiology and pathogenesis.

Main Results:

  • Analysis of retrieved articles provided insights into the causes and development of keloids.
  • Experimental studies on keloids were also included in the review.

Conclusions:

  • The primary cell responsible for keloid formation remains undetermined.
  • Keloid development may stem from an aberrant response to tissue injury, triggering inflammation and cytokine release (e.g., TGF-β1).
  • This process stimulates fibroblasts to produce excess collagen, a key feature of keloid disease.
