Insights

Eph receptors and ephrins are key signaling molecules in development and cancer. Understanding their bidirectional signaling in stem cells and tumors offers therapeutic potential for human diseases.

Area of Science:

  • Molecular Biology
  • Cell Signaling
  • Developmental Biology
  • Cancer Biology

Background:

  • Eph tyrosine kinase receptors and their ephrin ligands mediate crucial signaling pathways.
  • These pathways are vital for development, tissue maintenance, and the progression of cancer (tumorigenesis).
  • Bidirectional signaling occurs between receptor-expressing and ligand-expressing cells upon Eph-ephrin binding.

Purpose of the Study:

  • To highlight the significance of Eph receptors and ephrins in biological processes.
  • To underscore their role in adult stem cell niches and tumor microenvironments.
  • To emphasize their potential as therapeutic targets for human diseases.

Main Methods:

  • Review and synthesis of existing literature on Eph-ephrin signaling.
  • Analysis of the expression patterns of Eph receptors and ephrins in stem cells and tumors.
  • Discussion of the functional implications of bidirectional signaling in these contexts.

Main Results:

  • Eph receptors and ephrins are frequently expressed in adult stem cell niches and tumors.
  • Their functions in these specific environments are increasingly recognized but not fully elucidated.
  • Bidirectional signaling mediated by Eph-ephrin interactions plays a complex role in both normal and pathological conditions.

Conclusions:

  • Eph receptors and ephrins are critical regulators of fundamental biological processes.
  • Their involvement in tumorigenesis makes them significant targets for cancer research.
  • Further investigation into Eph-ephrin signaling holds promise for developing novel therapeutic strategies.

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal01:22

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.
Stem Cell Niche01:26

Stem 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...
Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

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...
Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
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,...
