Renewal of Skin Epidermal Stem Cells01:12

Renewal of Skin Epidermal Stem Cells

2.4K
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...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

3.6K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

2.4K
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...

Pigmentation01:19

Pigmentation

3.8K
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...

Cells of the Epidermis01:24

Cells of the Epidermis

7.2K
The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption01:22

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

861
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

  • Skin Aging Research
  • Epidermal Homeostasis

Background:

  • The epidermis plays a crucial role in maintaining body homeostasis.
  • Changes in epidermal structure and function occur throughout the lifespan.
  • Understanding molecular mechanisms of epidermal maintenance necessitates new therapeutic strategies for skin aging.

Purpose of the Study:

  • To review active ingredients that counteract epidermal aging symptoms.
  • To provide a functional classification of these ingredients based on regulated epidermal functions.
  • To identify compounds with potential cosmetic and dermatological applications.

Main Methods:

  • Literature review of active ingredients targeting specific epidermal functions.
  • Classification based on regulation of keratinocyte proliferation and differentiation.
  • Categorization by agents maintaining water-ion balance.
  • Identification of compounds enhancing immunological defense.
  • Grouping of antioxidants improving UV protection and activity.

Main Results:

  • Compounds (excluding retinoids) influence keratinocyte proliferation and differentiation, strengthening the skin barrier.
  • Natural lipids, glycerol, and urea are effective in maintaining skin water-ion balance.
  • Natural extracts like resveratrol can bolster the skin's immunological defense.
  • Antioxidants (flavonoids, vitamin C) enhance protection against solar radiation and improve epidermal antioxidant capacity.

Conclusions:

  • Active ingredients can be functionally classified by their regulation of age-affected epidermal functions.
  • This classification aids in developing targeted treatments for skin aging.
  • Identified ingredients hold promise for cosmetic and dermatological applications in promoting epidermal homeostasis.
