Cell potency is a cell's ability to differentiate into other cell types. [1] [2] The more cell types a cell can differentiate into, the greater its potency.Potency is also described as the gene activation potential within a cell, which like a continuum, begins with totipotency to designate a cell with the most differentiation potential, pluripotency, multipotency, oligopotency, and finally ...
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 ...
One type of pluripotent cell, called a hematopoietic stem cell, can differentiate into a large variety of cells with different functions. This stem cell can produce red blood cells, platelets, mast cells, dendritic cells, macrophages, lymphocytes, neutrophils, basophils, and eosinophils. Each of these cells have a different function, but they ...
Directed differentiation is a bioengineering methodology at the interface of stem cell biology, developmental biology and tissue engineering. [1] It is essentially harnessing the potential of stem cells by constraining their differentiation in vitro toward a specific cell type or tissue of interest. [2]
Induced pluripotent stem cells are similar to natural pluripotent stem cells, such as embryonic stem cells, in many aspects, such as the expression of certain stem cell genes and proteins, chromatin methylation patterns, doubling time, embryoid body formation, teratoma formation, viable chimera formation, and potency and differentiability, but ...
When cells on one side of a stem grow longer and faster than cells on the other side, the stem will bend to the side of the slower growing cells as a result. This directional growth can occur via a plant's response to a particular stimulus, such as light ( phototropism ), gravity ( gravitropism ), water, ( hydrotropism ), and physical contact ...
In the derivation of human embryonic stem cell lines, embryos left over from in vitro fertilization (IVF) procedures are used. The fact that the blastocyst is destroyed during the process has raised controversy and ethical concerns. Embryonic stem cells are pluripotent, meaning they can differentiate to form all cell types in the body. In vitro ...
Cell potency, a measure of the differentiation potential of stem cells; In homeopathic dilutions, potency is a measure of how dilute a substance is; Potency in philosophy is a specific potentiality in Aristotle's Theory of Potentiality and actuality, or "Act and Potency"; e.g., since the material, stone, is potentially a statue, it has a ...
