Summary
Dental pulp stem cells (DPSCs) show significant variation, impacting their regenerative potential. Understanding DPSC heterogeneity is key to improving clinical outcomes and standardizing research.
Area of Science:
- Biomedical Engineering
- Stem Cell Biology
- Regenerative Medicine
Background:
- Dental pulp stem cells (DPSCs) are crucial for tissue regeneration.
- Significant heterogeneity exists within DPSC populations.
- This heterogeneity can influence their therapeutic efficacy.
Purpose of the Study:
- To review the determinants of dental pulp stem cell (DPSC) heterogeneity.
- To explore how DPSC heterogeneity affects regenerative properties.
Main Methods:
- Comprehensive literature search of PubMed, Scopus, and MEDLINE (Ovid).
- Focus on human dental pulp stem cell heterogeneity.
- Narrative review of identified studies.
Main Results:
- DPSCs exhibit considerable heterogeneity, with distinct subpopulations.
- Variations in proliferation and differentiation capabilities are observed.
- Intrinsic and extrinsic factors contribute to DPSC heterogeneity.
Conclusions:
- DPSC heterogeneity may explain inconsistent clinical results.
- Standardization of isolation and characterization methods is needed.
- Single-cell RNA sequencing can elucidate heterogeneity and guide standardization.

Stem cells are undifferentiated cells with extensive self-renewal properties that help them maintain their population during the fetal and adult stages of life. They can specialize in all cell types of the human body. However, their differential potential may vary and can be classified into five types. Stem cells can be (1) Totipotent, (2) Pluripotent, (3) Multipotent, (4) Oligopotent, and (5) Unipotent. Each stem cell has a specific origin; the fertilized egg or zygote is a totipotent cell and...

Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...

01:26Stem Cell Niche
5.3K
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...

5.6K
The process of blood cell formation is called hematopoiesis. Hematopoiesis starts early during development, on the seventh day of embryogenesis. This phase of hematopoiesis is called the primitive wave, wherein the extraembryonic yolk sac allows the production of erythroid cells and endothelial cells from a common precursor called hemangioblast. The erythroid cells provide oxygen to support the growth of the rapidly dividing embryo. Hemangioblasts later develop into hematopoietic stem cells or...

The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...
