Label	Id	Description
obsolete prespore cell	CL_0000267
obsolete meristemoid	CL_0000266	[Obsolete. Use PO:0004011 from Plant Ontology instead. A cell constituting an active locus of meristematic activity in a tissue composed of somewhat older, differentiating cells.]
blood island	UBERON_0003061	[Blood islands are structures in the developing embryo which lead to many different parts of the circulatory system. They primarily derive from plexuses formed from angioblasts. Within them, vacuoles appear through liquefaction of the central part of the syncytium into plasma. The lumen of the blood vessels thus formed is probably intracellular. The flattened cells at the periphery form the endothelium. The nucleated red blood corpuscles develop either from small masses of the original angioblast left attached to the inner wall of the lumen or directly from the flat endothelial cells. In either case the syncytial mass thus formed projects from and is attached to the wall of the vessel. Such a mass is known as a blood island and hemoglobin gradually accumulates within it. Later the cells on the surface round up, giving the mass a mulberry-like appearance. Then the red blood cells break loose and are carried away in the plasma. Such free blood cells continue to divide. Blood islands have been seen in the area vasculosa in the omphalomesenteric vein and arteries, and in the dorsal aorta[WP, unvetted].]
anterior cell	CL_0000261
obsolete mucilage cell	CL_0000260	[Obsolete. Use PO:0000373 from Plant Ontology instead. Cell containing mucilages or gums or similar carbohydrate material characterized by the property of swelling in water.]
humerus endochondral element	UBERON_0015053	[A humerus bone or its cartilage or pre-cartilage precursor.]
hindlimb endochondral element	UBERON_0015022	[A hindlimb bone or its cartilage or pre-cartilage precursor.]
orbitosphenoid endochondral element	UBERON_0015059	[A orbitosphenoid bone or its cartilage or pre-cartilage precursor.]
obsolete sclerenchyma cell	CL_0000276	[Obsolete. Use PO:0000077 from Plant Ontology instead. Cell variable in form and size, being more or less thick, often lignified, secondary walls. Belongs to the category of subcells and may or may not be devoid of protoplast at maturity.]
presumptive neural plate	UBERON_0007284	[A presumptive structure that has the potential to develop into a neural plate.]
obsolete prestalk B cell	CL_0000275

chordal neural plate	UBERON_0003057	[The portion of neural plate posterior to the mid-hindbrain junction.]
eye primordium	UBERON_0003071	[Portion of tissue that is part of the anterior neural keel and will form the optic vesicle[ZFA]. A paired ectodermal placode that becomes invaginated to form the embryonic lens vesicles.]
pre-chordal neural plate	UBERON_0003056	[The portion of neural plate anterior to the mid-hindbrain junction.]
