Analysis of the osteochondral unit of aquatic mammals reveals a distinctly different tissue structure, lacking the arcade-like collagen fiber organization, a calcified cartilage layer and a dense subchondral bone plate, typically seen in osteochondral tissue of terrestrial mammals.

Specification and expansion during rib development is explained by Agent-Based Modeling while respecting the locality of decision-making that occurs as millions of cells coordinate their behavior to form and refine spatial pattern.

When ancestral Xenopus returned to water ~170mya, they evolved a new method for producing courtship calls underwater without airflow, using vibrations that also preserve essential acoustic information on species identity.
Serum exosomal sequencing combined with cell and animal experiments indicate that miRNA-199b-5p is a novel miRNA associated with osteoarthritis (OA) and can modulate the onset and progression of the disease.

Chondrocytes derived from induced pluripotent stem cells with the dysplasia-causing TRPV4 mutations, V620I and T89I mutation, were resistant to BMP4-induced hypertrophy, suggesting a mechanism underlying the effects of TRPV4 dysfunction on the severity of skeletal dysplasia.

Robust wrinkling pattern of the frilled dragon’s spectacular erectile ruff emerges from an elastic instability during homogeneous growth of the embryonic neck fold frustrated by its attachment to adjacent tissues.
