  2. Stem cell - Wikipedia

    en.wikipedia.org/wiki/Stem_cell

    The molecular definition of a stem cell includes many more proteins and continues to be a topic of research. [29] By using human embryonic stem cells to produce specialized cells like nerve cells or heart cells in the lab, scientists can gain access to adult human cells without taking tissue from patients.

  3. Embryonic stem cell - Wikipedia

    en.wikipedia.org/wiki/Embryonic_stem_cell

    Embryonic stem cells (ESCs) are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage pre- implantation embryo. [1][2] Human embryos reach the blastocyst stage 4–5 days post fertilization, at which time they consist of 50–150 cells. Isolating the inner cell mass (embryoblast) using immunosurgery results in ...

  4. 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.

  5. Hematopoietic stem cell - Wikipedia

    en.wikipedia.org/wiki/Hematopoietic_stem_cell

    The definition of hematopoietic stem cell has developed since they were first discovered in 1961. [5] The hematopoietic tissue contains cells with long-term and short-term regeneration capacities and committed multipotent, oligopotent, and unipotent progenitors. Hematopoietic stem cells constitute 1:10,000 of cells in myeloid tissue.

  6. Neural stem cell - Wikipedia

    en.wikipedia.org/wiki/Neural_stem_cell

    Neural stem cells (NSCs) are self-renewing, multipotent cells that firstly generate the radial glial progenitor cells that generate the neurons and glia of the nervous system of all animals during embryonic development. [1] Some neural progenitor stem cells persist in highly restricted regions in the adult vertebrate brain and continue to ...

  7. Induced pluripotent stem cell - Wikipedia

    en.wikipedia.org/wiki/Induced_pluripotent_stem_cell

    Induced pluripotent stem cells (also known as iPS cells or iPSCs) are a type of pluripotent stem cell that can be generated directly from a somatic cell. The iPSC technology was pioneered by Shinya Yamanaka and Kazutoshi Takahashi in Kyoto, Japan, who together showed in 2006 that the introduction of four specific genes (named Myc, Oct3/4, Sox2 ...
