Insights

Advanced microscopy techniques enhance understanding of the dermo-epidermal junction, crucial for inherited skin fragility disorders like epidermolysis bullosa (EB). Current treatments offer limited benefit, but gene therapy shows future promise.

Area of Science:

  • Dermatology
  • Cell Biology
  • Genetics

Background:

  • The dermo-epidermal junction (DEJ) is a critical interface between the epidermis and dermis.
  • Ultrastructural and biomolecular research has significantly advanced our knowledge of the DEJ.
  • The DEJ plays a role in the pathogenesis of inherited skin fragility disorders.

Purpose of the Study:

  • To review ultrastructural and biomolecular aspects of the dermo-epidermal junction.
  • To explore the role of the DEJ in the pathogenesis of epidermolysis bullosa (EB).

Main Methods:

  • Transmission electron microscopy (TEM)
  • Immunoelectron microscopy
  • Immunofluorescence
  • Antigenic mapping

Main Results:

  • These methods have improved the understanding of DEJ ultrastructure and molecular composition.
  • Alterations in the DEJ are implicated in the development of epidermolysis bullosa.
  • Current therapeutic strategies for EB provide minimal patient benefit.

Conclusions:

  • Further research into the DEJ is essential for understanding and treating EB.
  • Gene therapy presents a potential future treatment for epidermolysis bullosa.
  • Existing treatments like genetic counseling and prenatal diagnosis offer limited advantages for EB patients.

Structural Protein Function01:56

Structural Protein Function

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity.  In bones and teeth, it mineralizes to form...
Desmosomes01:05

Desmosomes

The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are  essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein complexes comprising desmosomal...
Renewal of Skin Epidermal Stem Cells01:12

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 cells,...
Clinical Applications of Epidermal Stem Cells01:19

Clinical 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...
Cells of the Epidermis01:24

Cells 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...
Layers of the Epidermis01:21

Layers of the Epidermis

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...
