Summary
Adult stem cells are vital for tissue repair but can cause diseases like tumors or degenerative conditions when they malfunction. Understanding stem cell aging and renewal is key to treating these stem cell diseases.
Area of Science:
- Stem cell biology
- Regenerative medicine
Context:
- Adult stem cells are crucial for tissue maintenance and repair throughout an organism's lifespan.
- These cells possess self-renewal capabilities and differentiate into specialized cell types.
Purpose:
- To define and characterize adult stem cells.
- To introduce the concept and features of stem cell diseases.
- To explore the link between stem cell dysfunction and disease pathogenesis.
Summary:
- Adult stem cells, found in various tissues, regenerate cells to counteract daily wear and tear.
- Dysfunctional stem cell self-renewal or differentiation can lead to proliferative diseases (e.g., tumors) or degenerative diseases due to insufficient tissue repair.
- Stem cell aging also contributes to reduced tissue regeneration and disease.
Impact:
- Elucidating stem cell self-renewal, differentiation, and aging mechanisms is essential for understanding stem cell diseases.
- This knowledge can pave the way for novel diagnostic and therapeutic strategies for stem cell-related disorders.

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...

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:...

4.3K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

3.0K
Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...
