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 ...
Archaeocytes (from Greek archaios "beginning" and kytos "hollow vessel") or amoebocytes are amoeboid cells found in sponges. They are totipotent and have varied functions depending on the species. The structure of these cells match to that of the stem cells as of containing high cytoplasmic content that helps the cells to morph according to ...
In mammals, a few cells of the early embryo are induced by signals of neighboring cells to become primordial germ cells. Mammalian eggs are somewhat symmetrical and after the first divisions of the fertilized egg, the produced cells are all totipotent. This means that they can differentiate in any cell type in the body and thus germ cells.
The zygote is the earliest developmental stage. In humans and most other anisogamous organisms, a zygote is formed when an egg cell and sperm cell come together to create a new unique organism. The formation of a totipotent zygote with the potential to produce a whole organism depends on epigenetic reprogramming.
The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.
Muse cells (Multi-lineage differentiating stress enduring cell) are non-cancerous pluripotent stem cell found in adults. [83] [84] They were discovered in 2010 by Mari Dezawa and her research group. [83] Muse cells reside in the connective tissue of nearly every organ including the umbilical cord, bone marrow and peripheral blood.
Meristematic cells are totipotent, meaning they retain the ability to differentiate into any plant cell type. As they divide, they generate new cells, some of which remain meristematic while others differentiate into specialized cells that typically lose the ability to divide or produce new cell types.
Trophoblast stem cells (TSCs) are cells that can regenerate and they are similar to embryonic stem cells (ESCs) in the fact that they come from early on in the trophoblast lifetime. [9] In the placenta, these stem cells are able to differentiate into any trophoblast cell because they are pluripotent. [9]
