  2. Mesenchyme - Wikipedia

    en.wikipedia.org/wiki/Mesenchyme

    Primary mesenchyme is the first embryonic mesenchymal tissue to emerge, and it is produced from EMT in epiblast cells. In the epiblast , it is induced by the primitive streak through Wnt signaling , and produces endoderm and mesoderm from a transitory tissue called mesendoderm during the process of gastrulation .

  3. Stromal cell - Wikipedia

    en.wikipedia.org/wiki/Stromal_cell

    Stromal cells, or mesenchymal stromal cells, are differentiating cells found in abundance within bone marrow but can also be seen all around the body. Stromal cells can become connective tissue cells of any organ, for example in the uterine mucosa (endometrium), prostate, bone marrow, lymph node and the ovary.

  4. Ground tissue - Wikipedia

    en.wikipedia.org/wiki/Ground_tissue

    Parenchyma is a versatile ground tissue that generally constitutes the "filler" tissue in soft parts of plants. It forms, among other things, the cortex (outer region) and pith (central region) of stems, the cortex of roots, the mesophyll of leaves, the pulp of fruits, and the endosperm of seeds.

    This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...

  6. Parenchyma - Wikipedia

    en.wikipedia.org/wiki/Parenchyma

    Lung parenchyma showing damage due to large subpleural bullae. Parenchyma (/ p ə ˈ r ɛ ŋ k ɪ m ə /) [1] [2] is the bulk of functional substance in an animal organ or structure such as a tumour. In zoology, it is the tissue that fills the interior of flatworms. In botany, it is some layers in the cross-section of the leaf. [3]

  7. 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).

  8. Organ (biology) - Wikipedia

    en.wikipedia.org/wiki/Organ_(biology)

    For example, the gland's tissue that makes the hormones is the parenchyma, whereas the stroma includes the nerves that innervate the parenchyma, the blood vessels that oxygenate and nourish it and carry away its metabolic wastes, and the connective tissues that provide a suitable place for it to be situated and anchored.

  9. Epithelial–mesenchymal transition - Wikipedia

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

    The epithelial–mesenchymal transition (EMT) is a process by which epithelial cells lose their cell polarity and cell–cell adhesion, and gain migratory and invasive properties to become mesenchymal stem cells; these are multipotent stromal cells that can differentiate into a variety of cell types.
