Area of Science:
- Stem cell biology and regenerative medicine.
Background:
- Stem cell niches are specialized microenvironments crucial for stem cell function.
- The extracellular matrix is a key component of these niches, influencing stem cell behavior.
Purpose of the Study:
- To review the current understanding of stem cell niche characteristics and function.
- To explore the role of stem cell niches in regenerative medicine.
Main Methods:
- Literature review of scientific articles on stem cell niches.
- Analysis of fundamental niche characteristics, including the extracellular matrix.
- Case studies on hematopoietic and epithelial stem cell niches.
Main Results:
- Niches provide essential signals regulating stem cell self-renewal and differentiation.
- The extracellular matrix composition dictates niche properties and stem cell fate.
- Stem cell niches are critical for successful regenerative therapies.
Conclusions:
- Understanding stem cell niches is fundamental to advancing stem cell biology.
- Targeting niche components offers therapeutic potential in regenerative medicine.

Stem Cell Niche
6.4K
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...

Multipotency and Niche of Bulge Stem Cell
4.2K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

Ecological Niches
26.6K
All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

Embryonic Stem Cells
32.5K
Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Adult Stem Cells
33.9K
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Induced Pluripotent Stem Cells
28.1K
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...
