Clinical Applications of Epidermal Stem Cells

Clinical Applications of Epidermal Stem Cells

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 EpiSCs...

Skin Diseases and Disorders

Skin Diseases and Disorders

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...

Renewal of Skin Epidermal Stem Cells

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...

Changes in Skin Color: Clinical Perspectives

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Traits and States

Traits and States

Personality traits represent consistent patterns in behavior, thoughts, and emotions, reflecting an individual's tendencies across various situations. For example, extraversion, a well-known trait, manifests in individuals as talkative, energetic, and enthusiastic behaviors. These traits are stable over time, offering a reliable framework for predicting how people might act in different contexts. However, they do not define every moment of an individual's life. In contrast to traits, states are...

Introduction to Psychological Disorders

Introduction to Psychological Disorders

Abnormal behavior, often referred to as mental illness, results from changes in brain function that influence thought patterns, behaviors, and social interactions. Psychologists and psychiatrists typically assess abnormal behavior using three primary criteria: deviance, maladaptation, and personal distress, particularly when these traits persist over long periods.
Deviant Behavior
Deviance in behavior refers to actions or thought patterns that significantly diverge from societal norms or...

Area of Science:

Dermatology
Neuroscience
Psychiatry

Background:

Epidermal keratinocytes are crucial for skin barrier function.
Skin diseases like atopic dermatitis and psoriasis are linked to anxiety and depression.
Keratinocytes release chemical mediators in response to skin damage.

Purpose of the Study:

To hypothesize that epidermal pathology influences human emotional state.
To explore the pathways through which skin changes affect mental health.

Main Methods:

Review of existing literature on epidermal function, skin diseases, and neurochemical signaling.
Analysis of studies linking skin conditions to mental health outcomes.
Examination of the role of keratinocyte-derived mediators in brain function.

Main Results:

Epidermal keratinocytes produce and release various chemical mediators, including neurotransmitters.
Skin barrier impairment triggers the release of cytokines and other mediators.
Elevated cytokines and altered glucocorticoid levels in the skin are associated with mental state changes.

Conclusions:

Epidermal pathology can influence emotional state via neurochemical signaling from keratinocytes to the brain.
Multiple pathways exist for skin conditions to impact mental health.
Further research is warranted to fully elucidate the skin-brain axis in emotional regulation.
