Multipotency and Niche of Bulge Stem Cell01:06

Multipotency and Niche of Bulge Stem Cell

3.5K
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...

Area of Science:

  • Dermatology
  • Autoimmune Diseases
  • Hair Biology

Background:

  • Alopecia areata (AA) is an autoimmune condition causing nonscarring hair loss.
  • Atypical hair regrowth in AA is uncommon and diverse.
  • The targetoid pattern of hair regrowth was first identified in 1988.

Observation:

  • This report focuses on three distinct cases exhibiting the targetoid hair regrowth pattern.
  • The targetoid pattern represents a specific, albeit rare, manifestation of hair recovery in AA.
  • Detailed clinical observations of these cases were documented.

Findings:

  • Confirmation of the targetoid hair regrowth pattern in three new AA patients.
  • The study adds to the limited literature on this specific paradoxical regrowth phenomenon.
  • Highlights the variability of clinical presentations in alopecia areata.

Implications:

  • Enhances understanding of the spectrum of alopecia areata presentations.
  • May inform future diagnostic criteria and treatment considerations for AA.
  • Contributes to the broader knowledge of hair follicle regeneration in autoimmune conditions.
