Abstract: Skin stem cells play a key role in maintaining homeostasis and regeneration of the epidermis, ensuring 
continuous renewal of the skin and restoration of damaged areas. The article discusses modern concepts of the 
morphological and functional features of skin stem cell niches, as well as the mechanisms of their activation and 
differentiation. The latest research aimed at using these cells in tissue engineering and transplantation 
technologies, which open up new prospects for the treatment of skin diseases and injuries, is highlighted. 
Particular attention is paid to biomedical approaches to managing regenerative processes using stem cells to 
improve the effectiveness of therapy and create artificial skin substitutes.

Introduction: The skin is the largest organ of the human 
body and performs many vital functions, including 
barrier protection from external influences, 
participation in the immune response, temperature 
regulation and perception of sensory signals. The main 
layer of the skin responsible for renewal and 
restoration is the epidermis - a multi-layered 
epithelium that is constantly renewed throughout life 
due to the activity of stem cells. 

Skin stem cells are a specialized population pool of cells 
with a high capacity for self-reproduction and 
multifaceted differentiation. They provide 
regeneration and homeostasis maintenance of the 
epidermis, playing a key role in wound healing and 
restoration of damaged skin areas. These cells are 
localized in various specialized microenvironments - 
niches, such as the basal layer of the epidermis, hair 
follicles and sebaceous glands. The niche 
microenvironment maintains the stem properties of 
cells and regulates their proliferation and 
differentiation through complex signaling pathways 

and interactions with surrounding cells and the 
extracellular matrix. 

Modern methods of molecular biology, cell 
visualization and genetic analysis allow us to better 
understand the mechanisms of activation of skin stem 
cells in response to damage and their role in dynamic 
regeneration processes. Disturbances in the 
functioning of these cells are associated with various 
pathologies, including chronic wounds, psoriasis, and 
skin cancer. 

In addition, the study of skin stem cells is important for 
the development of tissue engineering, a promising 
field aimed at creating bioengineered skin substitutes 
and effective transplantation methods. The use of stem 
cells in regenerative medicine opens new horizons for 
the treatment of burns, wounds, as well as genetic and 
autoimmune skin diseases, improving the quality of life 
of patients. 

This article will review current understanding of the 
morphology and functional characteristics of skin stem 
cells, their niches, activation mechanisms, and role in

epidermal regeneration. Particular attention will be 
paid to the latest advances in tissue engineering and 
clinical application of these cells in transplantology. 

Purpose of the study 

To study modern concepts of skin stem cells, their 
niches and activation mechanisms, and to assess the 
prospects for their use in epidermal regeneration and 
tissue engineering. 

Materials and methods 

The PubMed , Scopus and Web databases were used to 
search for literature. of Science with filtering of articles 
published in the last 10 years. 

The analysis included the results of molecular 
biological, histological and experimental studies on 
models in in vitro and in vivo , which reveal the features 
of the morphology of skin stem cells and their 
functional activity. Particular attention was paid to 
works describing methods of culturing stem cells, tissue 
engineering models and clinical studies on the use of 
cell technologies in the treatment of skin lesions. 

When describing the mechanisms of stem cell 
activation, data on signaling pathways that influence 
cell proliferation and differentiation under 
physiological conditions and tissue damage were taken 
into account. 

RESULTS AND DISCUSSION 

Modern research confirms that skin stem cells are 
represented by several populations located in different 
niches of the epidermis, hair follicles and sebaceous 
glands. Each of these niches has unique 
microenvironments that support the stem properties 
of the cells and regulate their activation in response to 
physiological needs or skin damage. 

The cells of the basal layer of the epidermis provide 
constant renewal of the superficial layer of the skin due 
to the ability to self-reproduce and differentiate. Hair 
follicles contain a separate group of stem cells that 
participate not only in hair growth, but also in the 
reparation of the epidermis in case of damage. Pericytic 
and mesenchymal components of niches play an 
important role in the regulation of the cell cycle and 
immune response. 

Skin stem cell activation is mediated by a complex of 
signaling pathways, including Wnt /β- catenin , Notch , 
Hedgehog , and TGF-β, which ensure precise 
coordination of proliferation and differentiation. 
Disruptions in these pathways are associated with 
pathological processes, including delayed wound 
healing and cancer development. 

Significant advances have been made in tissue 
engineering through the development of methods for 

culturing and differentiating skin stem cells, allowing 
the creation of artificial skin substitutes that are close 
in structure and function to natural skin. Cellular 
technologies, including the use of mesenchymal stem 
cells and induced pluripotent stem cells ( iPSCs ), have 
shown high efficiency in regenerating damaged tissue 
and reducing inflammatory responses. 

Clinical studies show promise for the use of stem cells 
in the treatment of burns, chronic wounds and 
dermatological diseases, but challenges remain related 
to the control of differentiation, immunogenicity and 
graft integration. 

Thus, further understanding of the biology of skin stem 
cells and their niches, as well as the development of 
safe and effective cell therapies, are critical for progress 
in regenerative medicine and improving the quality of 
life of patients with skin pathologies. 

CONCLUSION 

Skin stem cells play a key role in maintaining 
homeostasis and regeneration of the epidermis, 
ensuring continuous renewal of the skin and recovery 
from damage. Modern research has significantly 
expanded our understanding of stem cell morphology, 
the characteristics of their niches and activation 
mechanisms, which opens up new opportunities for the 
development of effective methods of tissue 
engineering and skin transplantation. The use of stem 
cells in regenerative medicine contributes to the 
creation of innovative approaches to the treatment of 
burns, chronic wounds and other skin pathologies, 
improving the quality of life of patients. Further study 
of these cells and their microenvironments is important 
for improving clinical technologies and developing 
personalized therapy.
