Renewal of Skin Epidermal Stem Cells

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,...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Clinical Applications of Epidermal Stem Cells

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...

Signal Transduction: Overview

Signal Transduction: Overview

Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...

Diversity in Cell Signaling Responses

Diversity in Cell Signaling Responses

The physiological function of a cell and cellular communication are outcomes of a range of extrinsic signals, intracellular signaling pathways, and cellular responses. No two cell types express the same repertoire of signaling components. Receptors are highly selective for their cognate ligands, but once activated, they can alter multiple cellular processes such as DNA transcription, protein synthesis, and metabolic activity.
Graded and Abrupt Responses
Some signaling systems generate...

Summary

Endocannabinoids, including anandamide, regulate skin cell growth and differentiation. Dysregulation of the endocannabinoid system (ECS) is linked to skin diseases, making it a therapeutic target.

Background:

Endocannabinoids are endogenous lipid mediators influencing central and peripheral biological processes.
The skin's epidermis acts as a protective barrier, with differentiation being a key specialization mechanism.
Anandamide, a key endocannabinoid, impacts skin cell growth, differentiation, and death.

Purpose of the Study:

To review the roles of the endocannabinoid system (ECS) in skin pathophysiology.
To elucidate the molecular regulation of epidermal proliferation and differentiation by endocannabinoids.
To explore the link between ECS dysregulation and various skin diseases.

Main Methods:

Literature review of current knowledge on endocannabinoids and the ECS.
Analysis of molecular mechanisms regulating epidermal differentiation.
Examination of evidence linking ECS to skin disease pathogenesis.

Main Results:

The ECS is intricately involved in the regulation of mammalian epidermal proliferation and terminal differentiation (cornification).
The ECS is subject to fine-tuning by, and can influence, the epidermal differentiation program.
Disruption of ECS regulation is associated with skin conditions like acne, dermatitis, and psoriasis.

Conclusions:

The endocannabinoid system plays a significant role in maintaining skin homeostasis.
Imbalances in the ECS are implicated in the development of diverse dermatological disorders.
Targeting the ECS presents a promising therapeutic strategy for various skin diseases.
