Accessory Structures of the Skin: Hair Growth and Types

3.1K
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Multipotency and Niche of Bulge Stem Cell

4.4K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

Skin Diseases and Disorders

6.2K
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...

Autoimmune Disorders01:29

Autoimmune Disorders

2.2K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Folliculogenesis01:20

Folliculogenesis

3.6K
Folliculogenesis is the development of ovarian follicles, the specialized structures within the ovarian cortex where oogenesis, or egg development, occurs. This process is essential for female reproductive health and begins during fetal development when primordial follicles are formed. Each primordial follicle comprises a primary oocyte in the center, surrounded by a single layer of squamous pre-granulosa cells. These follicles remain dormant in late prophase I of meiosis until triggered by...

Accessory Structures of the Skin: Hair and Hair Follicles

5.6K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Area of Science:

  • Dermatology
  • Autoimmune Diseases
  • Trichology

Background:

  • Alopecia areata (AA) is an autoimmune condition causing nonscarring hair loss in all age groups.
  • Management is challenging for extensive or long-standing cases of AA.
  • Treatment selection depends on disease duration, activity, patient age, and extent.

Purpose of the Study:

  • To review the clinical presentation of alopecia areata.
  • To discuss the epidemiology and pathophysiology of AA.
  • To summarize current and emerging treatment options for AA.

Main Methods:

  • Literature review of clinical presentations.
  • Epidemiological data analysis.
  • Review of current and evolving therapeutic strategies for AA.

Main Results:

  • Alopecia areata presents with varied clinical features and affects diverse populations.
  • Effective and sustainable remission induction remains a challenge in extensive AA.
  • Treatment decisions are individualized based on specific patient and disease characteristics.

Conclusions:

  • There is currently no definitive cure for alopecia areata.
  • Management strategies for AA require careful consideration of multiple factors.
  • Ongoing research aims to develop more effective and sustained treatments for AA.
