Stem cell | Definition, Types, Uses, Research, & Facts | Britannica
2024年11月18日 · 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.
Biology of stem cells: an overview - PMC - PubMed Central (PMC)
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.
Cell Diagrams with Labelling Activity - Learnful
I've created two interactive diagrams for an upcoming open textbook for high-school level biology. The cell structure illustrations for these diagrams were generated in BioRender. Both diagrams feature a drag-and-drop labelling activity created with H5P here on Learnful. These h5p resources are made available openly with the CC BY license.
Stem cell - Wikipedia
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.
Stem Cell - The Definitive Guide - Biology Dictionary
2021年5月7日 · 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.
Schematic diagram of the stem cell niche showing the stem cells …
Stem cell niches are formed of extracellular matrix (ECM) and support cells, such as mesenchymal or stromal cells, that establish interactions with stem cell and provide them with paracrine...
Schematic diagram illustrating the stem cell hierarchy. Embryonic stem ...
Embryonic stem cells (ESCs) are pluripotent, and have the capacity to differentiate into cells of all three dermal layers, that is, endoderm, mesoderm and ectoderm. Adult stem cells are...
Adult stem cell - Wikipedia
To ensure self-renewal, stem cells undergo two types of cell division (see Stem cell division and differentiation diagram). Symmetric division gives rise to two identical daughter stem cells, whereas asymmetric division produces one stem cell and one progenitor cell with limited self-renewal potential. Progenitors can go through several rounds of cell division before finally differentiating ...
Stem Cells- Definition, Properties, Types, Uses, Challenges
2022年4月12日 · Stem cells are unique cells present in the body that have the potential to differentiate into various cell types or divide indefinitely to produce other stem cells. Stem cells are essential cells that replace damaged cells or cells lost due to diseases.
