The definition of cell is intended to represent all cells, and thus a cell is defined as a material entity and not an anatomical structure, which implies that it is part of an organism (or the entirety of one). +
To accommodate unicellular organisms better, 'cell in vivo' has been re-labeled 'native cell' to better represent its intended meaning - that is, that it is a cell in the context of a multicellular organism or in a natural environment. 'Native' is intended to contrast with 'in vitro', which refers to cells or other biological entities that have been intentionally placed in a controlled, non-natural setting for the purpose of study or manipulation. (MAH 1.12.12). +
TODO - distinguish generic olfactory apparatus from nose; we have olfactory organ for the generic organ - add new class 'olfactory structure'? +
A primitive exocrine pancreas can be found in holocephalan cartilaginous fish; a pancreatic duct directly ending in the gut lumen is connected to a glandular structure made of exocrine cells and associated with cell islets, which comprises three different hormone-producing cell types: insulin, somatostatin and glucagon (Yui and Fujita, 1986)[PMID:16417468] +
Taxon notes: The lamprey possesses a distinct pituitary organ and hormones, the ascidian does not show distinct evidence of them [Sower S, Freamat M, Kavanaugh S. The origins of the vertebrate hypothalamic遯ｶ闖殃tuitary遯ｶ蝣ｵonadal (HPG) and hypothalamic遯ｶ闖殃tuitary遯ｶ骰紘yroid (HPT) endocrine systems: new insights from lampreys. Gen Comp Endocrinol 2009;161:20-9] +
The class has been re-labeled to 'culture' instead of 'line', as this class intends to cover cultured cells of multicellular and unicellular organisms, and both immortal and mortal cultured cells. 'Cell line' has different meanings to different people, in some cases referring to a culture that has been passaged, and in others referring to cultures that are immortal. 'Cell line cell' is included, however, as a narrow synonym. +
Development notes: has developmental contribution from NC in verteberates (UBERONREF:0000002) +
Development notes: has developmental contribution from NC in verteberates (UBERONREF:0000002) +
we assume that mouse, HOG and GAID all mean zone of skin when they say skin. We also choose skin as an exact synonym, as it is more intuitive +
Editor notes - endocrine and exocrine pancrease are no co-associated in hagfishes or lampreys [PMID:20959416] - create a separate class for these? +
AO notes: FMA distinguishes Eye (subdivision of face) which has its parts an Eyeball (organ). MA includes eyelid, conjunctiva and lacrimal apparatus as part of MA:eye - consistent with FMA - so we can infer that MA:eye is more like FMA:eye than FMA:eyeball. For other AOs this distinction is less meaningful - e.g. ZFA has no eyelid; XAO has no eyelid, but it has conjuctiva, which is considered part of the xao:eye. GO considers eyelid development part of eye development. See also notes on optic nerve - XAO, AAO and BTO consider this part of the eye. MA considers the eye muscles part of the eye, whereas FMA has a class 'orbital content' for this +
GO includes tree trunks, but excludes antennae. We modify trunk to body in our definition. Note this is currently a subtype of organism subdivision - which would exclude feathers +
Morphology: mononuclear cell, diameter 12-20 _M, non-granular, N/C ratio 3/1 - 4/1; markers: CD11b (shared with many other myeloid cells); location: Adult: bone marrow; fetal: liver, Yolk Sac; role or process: hematopoiesis, monocyte development; lineage: hematopoietic, myeloid. +
AO notes: in FMA, tendon is an organ component that with parts dense-irregular-connective-tissue of tendon and dense-irregular-connective-tissue of tendon sheath; we follow VSAO in making it a subtype of the former. In VSAO tendons connect muscle to bone; in WP the def states integument (e.g. auricular muscles) - but JB confirms this is not actually tendon but aponeurosis +
TODO - check vert vs invert. Other species: Any of a number of aggregations of neurons, glial cells and their processes, surrounded by a glial cell and connective tissue sheath (plural: ganglia). // Subdivision of neural tree (organ) which primarily consists of cell bodies of neurons located outside the neuraxis (brain and spinal cord); together with a nucleus and its associated nerve, it constitutes a neural tree (organ). Examples: spinal ganglion, trigeminal ganglion, superior cervical ganglion, celiac ganglion, inferior hypogastric (pelvic) ganglion. // a cluster of nerve cells and associated glial cells (nuclear location) // Portion of tissue that contains cell bodies of neurons and is located outside the central nervous system. // Structures containing a collection of nerve cell bodies. (Source: BioGlossary, www.Biology-Text.com). +

TODO - make distinctions between duct and tube clearer. Single layer of cells vs multiples? Function (e.g. exocrine gland duct?). Different ontologies use it in different ways +
Note that MA:0000434 has subclasses upper and lower, so it corresponds to a segment of the tract, rather than the tract as a whole +
ZFA - The multi-tissue structure where the glomerular basement membrane supported by mesonephric podocytes filters blood from the glomerular capillaries. TODO - split glomerulus and glomerular tuft? DONE. GUDMAP: 'Together, the Bowman遯ｶ蜀ｱ capsule and the glomerulus comprise the definitive renal corpuscle.' - here the glomerulus is part of the capsule? +
Editor note: merge with non-neural. In vertebrates, the ectoderm has three parts: external ectoderm (also known as surface ectoderm), the neurectoderm (neural crest, and neural tube). +
Grouping term for query purposes. Notes that the developmental relationships are being refined such that most structures should develop in whole from at most one layer, but may have contributions from multiple +

By contrast to the pronephros, the histological features of the mesonephros, with its primitive glomeruli, suggest that it probably functions as a primitive kidney, and is involved in the production of much of the amniotic fluid. Within the two mesonephroi, one located on either side of the dorsal mesentery of the hindgut, a substantial number (in the region of about 40 or more) of cranio-caudally segmented mesonephric tubules are formed. It has, however, been suggested that only the most rostrally located 4-6 pairs of mesonephric tubules drain into the mesonephric portion of the nephric duct. This is now seen to extend along the length of the mesonephroi, being located towards their lateral sides. The mesonephros is also retained over a considerably longer period than the pronephros, but gradually undergoes regression in a cranio-caudal direction. While the rostral part displays clear evidence of regression its more caudal part appears to display evidence of functional activity. Within the medial part of the mesonephros, vesicles are formed, although no glomeruli are formed there in this species. It is, however, difficult to believe that the relatively enormous mesonephroi do not have an excretory role in the mouse, only serving as a base for gonadal differentiation. In the human embryo, the medial part of the mesonephric tubules enlarges, become invaginated by capillaries, and form glomeruli. These then take on an excretory role. In the mouse, the mesonephric ducts appear to be patent throughout their length[GUDMAP] comment: Taxon notes: The mesonephros persists and form the permanent kidneys in fishes and amphibians, but in reptiles, birds, and mammals, it atrophies and for the most part disappears rapidly as the permanent kidney (metanephros) begins to develop during the sixth or seventh week. By the beginning of the fifth month only the ducts and a few of the tubules of the mesonephros remain[WP] +
Development notes: The postimplantation derivatives of the trophectoderm, which make up most of the fetal part of the placenta[PMID:19829370] +
Morphology: Highly vesicular; markers: Surface: RANK, cFMS (MCSF receptor); Secreted: cathepsin K and TRAP (tartate resistant acid phosphatase); transcription factors: PU.1, cFOS, MITF, NFkB (p52); role or process: tissue remodelling: bone resorption; lineage: hematopoietic, myeloid. +
Mast cells are generally integrin beta-7-negative and positive for TLR2, TLR3, TLR4, TLR5, TLR7, TLR9, C3aR, C5aR, CR3, CR4, VEGF, FGF2, and renin. They can express MHC Class I and II on their surface. Activated murine mast cells (IgE+Antigen) were capable of expressing the following co-stimulatory molecules: CD95 (Fas), CD120b, CD137 (4-1BB), CD153 (CD30L), CD154 (CD40L), GITR, ICOSL, OX40L, PD-L1, and PD-L2. Note that there was some mouse strain variation. Mast cells have also been demonstrated to produce bFGF, CCL2, CCL4, CCL5, CCL11, CCL20, CXCL2, CXCL8, CXCL10, GM-CSF, IFN-gamma, IL-1, IL-2, IL-3, IL-8, IL-10, IL-11, IL-12, IL-13, IL-16, IL-25, IL-18, MIP-1, prostaglandin D2, SCF, TGF-beta, TNF-alpha, TSLP, VEGF, and XCL1. They express the transcription factors Transcription factors AP-1, GATA1, MITF, Notch2, PIAS3, PU.1, and STAT5. +
The term "neuroepithelial cell" is used to describe both this cell type and neurecto-epithelial cell (CL:0000710). +
From FMA: 9.07.2001: Endothelial cell has always been classified as a kind of epithelial cell, specifically a squamous cell but that is not true. First, endothelial cell can either be squamous or cuboidal (e.g. high-endothelial cell) and secondly, it has different embryological derivation (mesodermal) than a true epithelial cell (ectodermal and endodermal). The basis for present classification is the fact that it comprises the outermost layer or lining of anatomical structures (location-based) but a better structural basis for the differentia is the cytoskeleton of the cell. Endothelial cell has vimentin filaments while an epithelial cell has keratin filaments. [Onard]. +
do not include NIF_Subcellular:sao1702920020 Nucleus. Proposed CUMBO def from MM: A subcortical part of the nervous system consisting of a relatively compact group of cells that is distinguishable histologically that share a commonality of cytoarchitecture, chemoarchitecturel and connectivity. (comments: I put in "subcortical" because I don't think we consider either the cerebellar cortex or cerebral cortex to be nuclei. Some people distinguish between a nucleus and a laminar structure (see Wikipedia definition). However, there are structures identified as nuclei that are laminar, e.g., lateral geniculate nucleus, although they are not laminated in all species. Also, I put in "relatively compact" and "distiguishable by histology" because we have groups of cells, e.g., cholinergic cell groups, doparminergic cell groups that are related on the 3 criteria but which we don't tend to consider nuclei because they don't occupy an easily defined territory. But all is open to debate. +

Human beings only have an embryonic cloaca, which is split up into separate tracts during the development of the urinary and reproductive organs[WP]. We deliberately exclude the wbbt class here, but may in future have a grouping class +
Note that the term "urogenital sinus" may refer to the primitive urogenital sinus present as a transient developmental structure in most mammals or it may refer to a condition in which an unseptated cloaca persists in animals longer than normal[MP] +
TODO - check fly mouthpart. note in uberon we distinguish between the mouth and the oral opening. the mouth is part of the digestive tract. TODO - check isa parent subdivision of head - is it a subdivision of the head or digestive tract +
note MA includes as parts of 'oral region' the tongue, tonsils, etc, so an equivalence to the oral opening itself may not be appropriate. +
Pancreatic beta cells are also reportedly CD284-positive. Upon activation, they upregulate their CD14 expression. +
Myofibroblasts are alpha-SMA-positive, CD34-negative, CD45-negative. They are reportedly capable of secreting IL-1beta, IL-6, and TNF-alpha. +
Taxon notes: In humans the cerebrum has three parts: the archipallium, the paleopallium and the neopallium. The developing telencephalon or forebrain is divided into pallium and subpallium. In amphibians, the cerebrum includes archipallium, paleopallium and some of the basal nuclei. Reptiles first developed a neopallium, which continued to develop in the brains of more recent species to become the neocortex of humans and Old World monkeys. In fish, the archipallium is the largest part of the cerebrum. Some researchers suggest the early archipallium gave rise to the human hippocampus[WP] +
Note this groups both skeletal and non-skeletal ligaments. What is called a "ligament" in many AOs is actually a skeletal ligament +
Morphology: Diameter 30_M-80 _M, abundant cytoplasm, low N/C ratio, eccentric nucleus. Irregular shape with pseudopods, highly adhesive. Contain vacuoles and phagosomes, may contain azurophilic granules; markers: Mouse & Human: CD68, in most cases CD11b. Mouse: in most cases F4/80+; role or process: immune, antigen presentation, & tissue remodelling; lineage: hematopoietic, myeloid. +

Keratinocytes are reportedly CDw210a-negative, CDw210b-positive, CD281-positive, CD282-positive, CD285-positive, IL22Ra1-positive, Human keratinocytes are reportedly capable of secreting BD-2, BD-3, hCAP-18, CXCL1, CXCL5, CXCL8, elafin, MMP-3, NGAL, PDGF-A, S100A7, S100A8, and S100A9. Transcription factors: STAT3-positive. +
Taxon notes: The hyoid bone and the clavicle are the only bones located in the throat of mammals. +
Editor note: - check - mucosa vs region of mucosa. In FMA these are subtypes of Mucosa: Mucosa of gallbladder, tongue, .... The following are subtypes of Region of mucosa: Mucosa of zone of stomach, trachea, bronchus, dorsum of tongue.... Depends on whether the covered area is an organ or organ component. Uberon does not regard organ vs organ component as crucial distinction and thus collapses these into a single class deliberately +
obsoletion recommended. The current part_of children were chosen as the intersection of what is stated in wikipedia and in the FMA. NIF: We are including Limbic System because it is still used by neuroscientists and others, but as a data annotation term, it is very poor because it is not a clearly defined entity. +
consider merging with transitional epithelium. MA uses the label 'urothelium' exclusively. FMA uses 'transitional epithelium' and has 'urothelium' as a sibling. FMA also lists 'urothelium' as the only example of 'transitional epithelium' +
The term has been used in a few different ways: * It is a pair of nuclear masses which form the basal ganglia, along with the subthalamic nucleus and the substantia nigra. * It may also refer to both the basal ganglia and internal capsule collectively.[2] * According to the 1917 version of Gray's Anatomy, it is the combination of the lentiform nucleus (also known as the lenticular nucleus) and the caudate nucleus * According to BrainInfo it is a part of the basal ganglia comprising the globus pallidus and striatum +
Naming conventions for pod terms under discussion within phenoscape group. TODO - add distinct term for skeleton and place AAO class here +
AO notes: we place the MA term musculature here, rather than under uberon:musculature, as this seems more appropriate given the structure of MA +
AO notes: in FMA/NIF this is a superclass of PM/AM - in BTO it is the mereological sum. We go with superclass here, as we are naming the class in the singular. Editor notes: check relationship to secondary meninx +
Editor notes: in BTO this is part of the cochlear modiolus, but this leads to the CG being in both the nervous and skeletal systems +
Originally described in the dendritic cell ontology (DC_CL:0000021 )(PMID: 19243617). These cells are also CD1a-high, CD14-negative, CD207-positive (langerin), CD324-positive (E-cadherin), and DCIR-positive. They reside in the epidermis. +
todo - move metadata to GO and obsolete this class. Note the inconsistency between the usage of the label 'cell component' in GO and CARO +
Editor note: revise after CARO2. todo - check the inclusion of FMA 'cardinal body part here', and check child terms for consistency +
This class was sourced from CARO, which was initially sourced from FMA. Nomenclature changes have been made. Note also AEO introduces a class AEO:0000013 'single-cell tissue' +
