Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

2.7K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Skin Diseases and Disorders

3.9K
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...

Skin Cancer01:30

Skin Cancer

4.3K
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...

Accessory Structures of the Skin: Hair Growth and Types

1.5K
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 Cell01:06

Multipotency and Niche of Bulge Stem Cell

3.7K
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...

Overview of Regeneration and Repair01:19

Overview of Regeneration and Repair

4.1K
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

Area of Science:

  • Dermatology
  • Trichology
  • Hair Biology

Background:

  • African hair shafts and pigmented scalps present unique diagnostic challenges in scarring alopecia.
  • Black patients often experience multiple hair disorder types concurrently.
  • Thorough understanding of clinical findings is essential for accurate diagnosis.

Purpose of the Study:

  • To elucidate the differential diagnosis of scarring alopecia in Black patients.
  • To highlight the specific anatomical locations and associated conditions.
  • To improve diagnostic accuracy for hair loss conditions in this demographic.

Main Methods:

  • Review of clinical presentations and diagnostic criteria for various scarring alopecias.
  • Categorization of differential diagnoses based on scalp location (frontal, mid-scalp, posterior).
  • Emphasis on unique features of African hair and scalp relevant to diagnosis.

Main Results:

  • Frontal scalp differentials include traction alopecia and frontal fibrosing alopecia.
  • Mid-scalp conditions encompass central centrifugal cicatricial alopecia, fibrosing alopecia in pattern distribution, discoid lupus erythematosus, and lichen planopilaris.
  • Posterior scalp diagnoses primarily involve folliculitis decalvans, dissecting cellulitis, and acne keloidalis nuchae.

Conclusions:

  • Accurate diagnosis of scarring alopecia in Black patients necessitates awareness of specific hair/scalp features.
  • Location-based differential diagnosis is key to distinguishing between various cicatricial conditions.
  • Recognizing common co-occurring hair disorders improves patient management.
