Aug 7, 2024 · Stem cell, an undifferentiated cell that can divide to produce some offspring cells that continue as stem cells and some cells that are destined to differentiate (become specialized). Stem cells are an ongoing source of the differentiated cells that make up the tissues and organs of animals and plants.
May 7, 2021 · Definition. A stem cell, found in embryos (embryonic stem cell) and adults (somatic stem cell), is an immature, non-specialized cell that can differentiate into one or more specific functioning or regenerating cell types. This makes them of use in the treatment of degenerating diseases.
In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can change into various types of cells and proliferate indefinitely to produce more of the same stem cell. They are the earliest type of cell in a cell lineage. [1]
Mar 23, 2024 · Stem cells are a special type of cells that have two important properties. They are able to make more cells like themselves. That is, they self-renew. And they can become other cells that do different things in a process known as differentiation. Stem cells are found in almost all tissues of the body.
I. Introduction: What are stem cells, and why are they important? Stem cells have the remarkable potential to renew themselves. They can develop into many different cell types in the body during early life and growth. Researchers study many different types of stem cells.
Aug 15, 2011 · Stem cells are defined as precursor cells that have the capacity to self-renew and to generate multiple mature cell types. Only after collecting and culturing tissues is it possible to classify cells according to this operational concept.
What are stem cells, and why are they important? What are the unique properties of all stem cells? How do you culture stem cells in the laboratory? How are stem cells used in biomedical research and therapies? How does NIH support stem cell research?
Jun 27, 2023 · Stem cells are basic cells that can become almost any type of cell in the body. Human stem cells can come from an embryo or an adult human.
Stem cells are special cells that can turn into different types of cells. In a developing embryo, they can develop into any type of cell. Once the body is grown, they can develop into specific cell types, to replace old or damaged cells.
Feb 26, 2021 · Stem cell. (1) An unspecialized cell characterized by the ability to self-renew by mitosis while in an undifferentiated state, and the capacity to give rise to various differentiated cell types by cell differentiation. (2) A cell that has not yet acquired a special function.
