Summary
The mesenchymal phenotype, traditionally linked to structural support or transient developmental phases, may signify undifferentiated and multipotent states in both embryonic development and adult tissues, extending beyond cancer research insights.
Area of Science:
- Developmental Biology
- Cell Biology
- Cancer Research
Background:
- The mesenchymal phenotype is traditionally viewed as a transient epithelial-to-mesenchymal transition (EMT) phase or as characteristic of structural support cells.
- Recent cancer research suggests mesenchymal traits in cancer cells can indicate stem cell properties and hybrid epithelial/mesenchymal states.
Purpose of the Study:
- To investigate the broader role of the mesenchymal phenotype beyond cancer.
- To determine if mesenchymal states represent undifferentiated and multipotent characteristics in normal development.
Main Methods:
- Analysis of publicly available single-cell transcriptome datasets.
- Examination of datasets from early embryonic stages and adult tissues.
Main Results:
- Mesenchymal phenotypes were observed in cells during embryonic development.
- Mesenchymal traits were also identified in adult tissues, suggesting a role in normal cellular states.
- These findings support the hypothesis that mesenchymal states correlate with undifferentiation and multipotency.
Conclusions:
- The mesenchymal phenotype may be a morphological indicator of undifferentiated and multipotent cell states.
- This concept extends beyond pathological contexts, applying to both embryonic development and adult organ homeostasis.
- Re-evaluating the mesenchymal phenotype's role in normal biology is warranted.

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

2.5K
How does a complex organism such as a human develop from a single cell? It all starts from a single fertilized egg which gives rise to a vast array of cell types, such as nerve cells, muscle cells, and epithelial cells that characterize the adult? Throughout development and adulthood, cellular differentiation leads cells to assume their final morphology and physiology. Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions.

2.9K
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.

During early development, the embryo forms two types of connective tissues— the mesenchyme and mucoid connective tissue.
The mesenchyme is the first connective tissue that emerges in the developing embryo. It consists of loosely arranged multipotent mesenchymal cells and reticular fibers in the extracellular matrix. This loose arrangement allows easy migration of cells, which is essential for germ layer positioning, patterning, and organ morphogenesis during embryonic development.

During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In...

Animal and protozoan cells do not have cell walls to help maintain shape and provide structural stability. Instead, these eukaryotic cells secrete a sticky mass of carbohydrates and proteins into the spaces between adjacent cells. This network of proteins and molecules is called an extracellular matrix or ECM.
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...
