  2. Stem cell - Wikipedia

    en.wikipedia.org/wiki/Stem_cell

    Neural stem cells are committed to the neuronal lineages (neurons, astrocytes, and oligodendrocytes), and thus their potency is restricted. [22] Nearly all research to date has made use of mouse embryonic stem cells (mES) or human embryonic stem cells (hES) derived from the early inner cell mass. Both have the essential stem cell ...

  3. Tylosis (botany) - Wikipedia

    en.wikipedia.org/wiki/Tylosis_(botany)

    These products are produced by the cambium and transported to the centre of the stem by cellular structures called medullary rays radiating from the center of the stem [5] and then enter living axial paratracheal parenchyma cells. As the wood ages, the contents of the parenchyma cell burst into the dead vessel through the pit linking the two.

  4. Cell culture - Wikipedia

    en.wikipedia.org/wiki/Cell_culture

    Stem cell culture is also used to harvest the molecules and exosomes that the stem cells release for the purposes of therapeutic development. [ 46 ] Biological products produced by recombinant DNA (rDNA) technology in animal cell cultures include enzymes , synthetic hormones , immunobiologicals ( monoclonal antibodies , interleukins ...

  5. Stem-cell therapy - Wikipedia

    en.wikipedia.org/wiki/Stem-cell_therapy

    Stem cells are being explored for use in conservation efforts. Spermatogonial stem cells have been harvested from a rat and placed into a mouse host and fully mature sperm were produced with the ability to produce viable offspring. Currently research is underway to find suitable hosts for the introduction of donor spermatogonial stem cells.

  6. 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.

  7. 3D cell culture in wood-based nanocellulose hydrogel

    en.wikipedia.org/wiki/3D_cell_culture_in_wood...

    Different cell lines and cell types have been cultured in NFC, including e.g. differentiation of human hepatic cells to functional organotypic cultures, [8] and proliferation of human pluripotent stem cells. [4] Organotypic liver cell cultures can be used in drug discovery for testing liver toxicity and metabolism of the novel drug candidates.

  8. Bone marrow - Wikipedia

    en.wikipedia.org/wiki/Bone_marrow

    The patient's own marrow is first killed off with drugs or radiation, and then the new stem cells are introduced. Before radiation therapy or chemotherapy in cases of cancer, some of the patient's hematopoietic stem cells are sometimes harvested and later infused back when the therapy is finished to restore the immune system. [34]

  9. Hematopoietic stem cell transplantation - Wikipedia

    en.wikipedia.org/wiki/Hematopoietic_stem_cell...

    Stem-cell transplantation was pioneered using bone marrow-derived stem cells by a team at the Fred Hutchinson Cancer Research Center from the 1950s through the 1970s led by E. Donnall Thomas, whose work was later recognized with a Nobel Prize in Physiology or Medicine. Thomas' work showed that bone-marrow cells infused intravenously could ...
