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...

Replicative Cell Senescence02:15

Replicative Cell Senescence

3.6K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

Abnormal Proliferation02:23

Abnormal Proliferation

4.5K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Adrenal Gland Disorders01:27

Adrenal Gland Disorders

1.4K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Anorexia Nervosa01:28

Anorexia Nervosa

46
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.
Symptoms and Physical Effects
Individuals with anorexia nervosa commonly exhibit extreme...

Alternative RNA Splicing02:18

Alternative RNA Splicing

21.0K
Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

Summary

A rare hair growth disorder causes short, thin scalp hair from birth. This case study details a healthy 10-year-old girl with this condition, highlighting diagnostic findings.

Area of Science:

  • Pediatric Dermatology
  • Genetics
  • Trichology

Background:

  • Congenital hair abnormalities are rare conditions affecting scalp hair from birth.
  • Understanding the clinical and microscopic features is crucial for diagnosis.

Purpose of the Study:

  • To describe a case of a healthy child with congenital short and thin scalp hair.
  • To detail the diagnostic investigations and findings for this rare hair condition.

Main Methods:

  • Clinical examination including dermatoscopy.
  • Microscopic examination of hair shafts.
  • Trichogram to assess hair cycle phases.

Main Results:

  • Short, thin, dark hair (millimeter to 2 cm) on scalp periphery; longer hair (5-8 cm) on midscalp.

  • Dermatoscopy showed tapered ends, not cut ends.
  • Trichogram revealed an anagen to telogen ratio of 68:32; no hair shaft abnormalities.

    • Conclusions:

    • The patient presents with a rare congenital hair disorder characterized by short, thin hair.
    • Diagnostic methods confirmed the absence of hair shaft abnormalities and a normal anagen/telogen ratio, suggesting a unique hair growth pattern.
