Permanent cells are
cell
Cell most often refers to:
* Cell (biology), the functional basic unit of life
Cell may also refer to:
Locations
* Monastic cell, a small room, hut, or cave in which a religious recluse lives, alternatively the small precursor of a monastery ...
s that are incapable of
regeneration
Regeneration may refer to:
Science and technology
* Regeneration (biology), the ability to recreate lost or damaged cells, tissues, organs and limbs
* Regeneration (ecology), the ability of ecosystems to regenerate biomass, using photosynthesis

. These cells are considered to be
terminally differentiated and
non-proliferative in postnatal life. This includes
neurons,
heart cells,
skeletal muscle cells and
red blood cells. Although these cells are considered permanent in that they neither reproduce nor transform into other cells, this does not mean that the body cannot create new versions of these cells. For instance, structures in the
bone marrow produce new red blood cells constantly, while skeletal muscle damage can be repaired by underlying
satellite cells
Myosatellite cells, also known as satellite cells, muscle stem cells or MuSCs, are small multipotent cells with very little cytoplasm found in mature muscle. Satellite cells are precursors to skeletal muscle cells, able to give rise to satellite ...
, which fuse to become a new skeletal muscle cell.
Disease and
virology
Virology is the scientific study of biological viruses. It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host cells for reproduction, th ...
studies can use permanent cells to maintain cell count and accurately quantify the effects of
vaccines
A vaccine is a biological preparation that provides active acquired immunity to a particular infectious or malignant disease. The safety and effectiveness of vaccines has been widely studied and verified.[< ...]

embryology
Embryology (from Greek ἔμβρυον, ''embryon'', "the unborn, embryo"; and -λογία, ''-logia'') is the branch of animal biology that studies the prenatal development of gametes (sex cells), fertilization, and development of embryos ...
studies also use permanent cells to avoid harvesting
embryonic cells from pregnant animals; since the cells are permanent, they may be harvested at a later age when an animal is fully developed.
