Uberon definition : A modified lobulated sebaceous gland at the rim of an eyelid, responsible for the
supply of meibum.;
Uberon synonym : glandula tarsales; gland of Meibom; Meibomian gland;
Uberon related term : tarsoconjunctival gland; palpebral gland;
Uberon Development note : in mice, meibomian gland development is initiated around E18.5 with the formation
of an epithelial placode and mesenchymal condensation, similar to that observed in
hair follicle development; invagination of the epithelium into the developing mesenchyme
then continues from birth to about P3 with initial branching of the epithelial cord
detected at P5; by P8 the developing meibomian gland shows extensive ductal branching
and the formation of distinct acini with mature meibomian glands present by P15 or
eyelid opening[PMID:20664693];
