|January 26, 2022
Summary
Identifying epidermal stem cells and understanding skin differentiation remain challenging. This review analyzes lineage tracing, stem cell research, and Wnt signaling to model epidermal development.
Area of Science:
- Dermatology
- Developmental Biology
- Stem Cell Biology
Background:
- The precise identification of epidermal stem cells is currently unknown.
- The mechanism underlying epidermal differentiation is not fully elucidated.
- Existing research provides insights into basal layer dynamics, hair follicle stem cells, and interfollicular epidermal stem cells.
Purpose of the Study:
- To collate and analyze existing literature on epidermal stem cells and differentiation.
- To present models of basal layer cellular composition.
- To present models of epidermal differentiation.
Main Methods:
- Literature review and analysis.
- Collating research on lineage tracing and clonal growth.
- Analyzing the role of Wnt signaling in development and differentiation.
Main Results:
- Synthesized information on epidermal stem cell research.
- Presented models for basal layer composition.
- Provided models for epidermal differentiation processes.
Conclusions:
- The study consolidates current knowledge on epidermal stem cells and differentiation.
- Models are proposed to advance understanding of epidermal development.
- Further research is needed for definitive identification and mechanistic understanding.

01:12Renewal of Skin Epidermal Stem Cells
2.7K
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...

01:24Cells of the Epidermis
5.3K
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...

01:21Layers of the Epidermis
5.6K
The epidermis, the outermost layer of the skin, is composed of several distinct layers. From deep to superficial, the layers of the epidermis are as follows:
Stratum Basale
Stratum basale, also known as the stratum germinativum, is the deepest layer of the epidermis. It is composed of a single layer of actively dividing cells called basal cells or basal keratinocytes. These cells constantly undergo cell division to replenish the upper layers of the epidermis. Additionally, melanocytes, which...

00:57Cellular Differentiation
4.0K
How does a complex organism such as a human develop from a single cell? It all starts from a single fertilized egg which gives rise to a vast array of cell types, such as nerve cells, muscle cells, and epithelial cells that characterize the adult? Throughout development and adulthood, cellular differentiation leads cells to assume their final morphology and physiology. Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions.

01:19Clinical Applications of Epidermal Stem Cells
2.8K
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...

01:06Multipotency and Niche of Bulge Stem Cell
3.9K
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...
