Furthermore, the constructs formed ear-shaped cartilage-like tissues at 12 weeks, which revealed a tissue structure with abundant cartilage extracellular matrices and mature lacuna.
Nine-year-old Kieran was born deaf and also had a rare condition which meant he did not have fully formed ears – only small lobes where his ears should have been.
The first piece in the exhibition, displayed in a vitrine like a religious relic in an otherwise nearly empty room, doubles as a helmet for, and portrait of, Charles V.

At the terminal spikelet stage, the shoot apex is a fully formed embryo ear and further development is described in section "Ear and ear formation".
Snakes have fully formed inner ear structures but no eardrum.
"This field has the potential to generate customized replacement parts for the human body, or even create organs containing capabilities beyond what human biology ordinarily provides". Standard tissue engineering involves seeding types of cells, such as those that form ear cartilage, onto a scaffold of a polymer material called a hydrogel.
The juvenile specimens preserve the proximal podomeres: the coxa (equivalent to the basipod of non-chelicerate arthropods) is expanded, with a length/width ratio of < 2.0, and has its anterior margin expanded to form an ear, although the exact shape of the ear cannot be ascertained.
The ear vesicle, acting on the surrounding mesenchyme, induces the latter to aggregate around the labyrinth and form the ear capsule.
