Pigmentation

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

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...

Natural and Artificial Concepts

Natural and Artificial Concepts

In psychology, concepts can be divided into two categories: natural and artificial. Natural concepts are formed through direct or indirect experiences. For example, consider the concept of snow. If you live in a place with regular snowfall, such as Essex Junction, Vermont, you know snow through direct experiences. You’ve seen it fall, touched it, shoveled it, and played in it. You recognize its texture, appearance, and even its smell. In contrast, if you live on an island like Saint...

Skin Cancer

Skin Cancer

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...

Design Example: Creating a Hydraulic Model of a Dam Spillway

Scaled hydraulic models of dam spillways provide a practical way to replicate and study the intricate flow dynamics of these structures. Often built to a 1:15 ratio, these models allow for observing critical water behavior, such as velocity distribution, flow patterns, and energy dissipation.

Sensory Functions of the Skin

Sensory Functions of the Skin

The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

Background:

Skin acts as a barrier and renews cells throughout life.
Melanocytes produce melanin, crucial for skin/hair color and UV protection.
Dysfunctional melanocytes cause albinism, vitiligo, and increase skin cancer risk.

Purpose of the Study:

To investigate the potential of multilineage-differentiating stress-enduring (Muse) cells for generating melanocytes.
To create three-dimensional (3D) reconstituted skin using Muse cell-derived cells.

Main Methods:

Muse cells were isolated from human fibroblasts and adipose tissue.
Muse cells were differentiated into melanocytes (Muse-MC), fibroblasts, and keratinocytes.
3D reconstituted skin was created using these differentiated cells.

Main Results:

Muse-MC expressed melanocyte markers (tyrosinase, DCT) and exhibited tyrosinase activity.
Differentiated Muse cells formed functional epidermis layers in 3D reconstituted skin.
Muse-MC were correctly localized in the basal layer of the reconstructed epidermis.

Conclusions:

Muse cells are a viable source for generating melanocytes and other skin cells.
Muse cells hold promise for skin reconstruction and rejuvenation medicine.
This study demonstrates the potential of endogenous skin stem cells for therapeutic applications.
