Summary
Researchers have advanced the study of epithelial skin stem cells using new labeling and isolation techniques. However, definitively identifying stem cells in living tissue remains a challenge for molecular analysis.
Area of Science:
- Dermatology
- Stem Cell Biology
- Molecular Biology
Background:
- Significant advancements have been made in understanding epithelial skin stem cells.
- New methodologies for labeling, tracking, isolating, and characterizing stem cell populations have been developed.
Purpose of the Study:
- To summarize current in vivo and in vitro assays for analyzing skin epithelial stem cells.
- To highlight the challenges in definitively identifying stem cells in intact tissue.
- To focus on methods for analyzing hair follicle stem cells due to extensive research.
Main Methods:
- Review of in vivo and in vitro assays for stem cell analysis.
- Discussion of techniques for labeling, tracking, and isolation of stem cells.
- Emphasis on methods applicable to hair follicle stem cells.
Main Results:
- Current stem cell definition is primarily functional.
- Unambiguous identification of stem cells within intact tissue is not yet achievable.
- Limitations exist in molecular studies of the stem cell compartment.
Conclusions:
- Despite progress, a definitive molecular identification of skin epithelial stem cells is still lacking.
- Functional assays remain crucial for stem cell analysis.
- Further research is needed to overcome limitations in molecular studies of stem cell compartments, particularly in hair follicles.

01:12Renewal 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,...
01:19Clinical 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...
01:33Adult Stem Cells
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously renew...
01:26Stem Cell Niche
The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...
01:24Cells of the Epidermis
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...

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