  2. Stem cell - Wikipedia

    Stem cell tourism is the part of the medical tourism industry in which patients travel to obtain stem cell procedures. [109] The United States has had an explosion of "stem cell clinics". [110] Stem cell procedures are highly profitable for clinics. The advertising sounds authoritative but the efficacy and safety of the procedures is unproven.

  3. Phenotypic plasticity - Wikipedia

    en.wikipedia.org/wiki/Phenotypic_plasticity

    Phenotypic plasticity refers to some of the changes in an organism's behavior, morphology and physiology in response to a unique environment. [1] [2] Fundamental to the way in which organisms cope with environmental variation, phenotypic plasticity encompasses all types of environmentally induced changes (e.g. morphological, physiological, behavioural, phenological) that may or may not be ...

  4. Mesenchymal stem cell - Wikipedia

    en.wikipedia.org/wiki/Mesenchymal_stem_cell

    Mesenchymal stem cells (MSCs), also known as mesenchymal stromal cells or medicinal signaling cells, are multipotent stromal cells that can differentiate into a variety of cell types, including osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells which give rise to marrow adipose tissue).

  5. Adult stem cell - Wikipedia

    en.wikipedia.org/wiki/Adult_stem_cell

    A stem cell possesses two properties: . Self-renewal is the ability to go through numerous cycles of cell division while still maintaining its undifferentiated state. Stem cells can replicate several times and can result in the formation of two stem cells, one stem cell more differentiated than the other, or two differentiated cells.

  6. Developmental plasticity - Wikipedia

    en.wikipedia.org/wiki/Developmental_plasticity

    The differentiation of stem cell precursors into specialized neurons gives rise to the formation of synapses and neural circuits, which is key to the principle of plasticity. [14] During this pivotal point in development, consequent developmental processes like the differentiation and specialization of neurons are highly sensitive to exogenous ...

  7. Epithelial–mesenchymal transition - Wikipedia

    en.wikipedia.org/wiki/Epithelial–mesenchymal...

    Epithelial and mesenchymal cells differ in phenotype as well as function, though both share inherent plasticity. [2] Epithelial cells are closely connected to each other by tight junctions, gap junctions and adherens junctions, have an apico-basal polarity, polarization of the actin cytoskeleton and are bound by a basal lamina at

  8. Cancer stem cell - Wikipedia

    en.wikipedia.org/wiki/Cancer_stem_cell

    The cancer stem cell model, also known as the Hierarchical Model proposes that tumors are hierarchically organized (CSCs lying at the apex [6] (Fig. 3).) Within the cancer population of the tumors there are cancer stem cells (CSC) that are tumorigenic cells and are biologically distinct from other subpopulations [7] They have two defining features: their long-term ability to self-renew and ...

  9. Dedifferentiation - Wikipedia

    en.wikipedia.org/wiki/Dedifferentiation

    Cell plasticity is the idea that cells can switch phenotypes in response to environmental cues. [13] In the context of regeneration, this environmental cue is damage or injury to a limb. [9] Cell plasticity is closely related to dedifferentiation, implying that a cell with ‘plasticity’ can dedifferentiate to change phenotypes. [9]
