Summary
Adult stem cells drive tissue repair and regeneration. This review compares stem cell roles in skin, cornea, lung, and intestine, proposing a hierarchical model based on stem cell potency and niche signals.
Area of Science:
- Stem cell biology and regenerative medicine.
Background:
- Adult stem cells are crucial for lifelong tissue maintenance, repair, and regeneration.
- Stem cell characteristics and their microenvironmental niches (niches) exhibit significant variation across different tissues.
Purpose of the Study:
- To compare stem cell differentiation and contribution to tissue maintenance and regeneration in the epithelia of the skin, cornea, lung, and intestine.
- To propose a hierarchical model for adult stem cells based on stem cell potency within specific tissue contexts.
Main Methods:
- Comparative review of stem cell populations and their functions across diverse epithelial tissues.
- Analysis of the relationship between stem cell potency, tissue maintenance/repair/regeneration, and niche-derived cues.
Main Results:
- Stem cell populations and their niches vary considerably even in related tissues.
- A hierarchical model is proposed where stem cell potency is defined by their capacity for tissue maintenance, repair, and regeneration.
- Niche signals play a critical role in maintaining the specific potency of stem cells.
Conclusions:
- Stem cell potency is a key determinant of tissue regeneration capacity.
- The proposed hierarchical model provides a framework for understanding adult stem cell behavior across different tissues.
- Understanding niche-stem cell interactions is essential for harnessing regenerative potential.

01:33Adult Stem Cells
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 renew...
01:18Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...

01:26Stem 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...
01:23Renewal of Intestinal Stem Cells
The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the goblet,...
01:12Renewal 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,...
01:17Stem Cell Culture
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...
