Cyclin‐dependent kinase 13 is indispensable for normal mouse heart development

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 616-630, April 2025.
Congenital heart disease (CHD) is the most common defect in live births. The role of cyclin‐dependent kinase (CDK13) in cardiogenesis and CHD was studied using a transgenic mouse model (Cdk13tm1b) carrying deletion of exons 3 and 4, causing loss of function.

Life history data derived from the dental histological analysis of Giraffa camelopardalis: Implications for the palaeohistology of extinct giraffids

open access: yesJournal of Anatomy, EarlyView.
The study of incremental lines in the dentine (left), cementum (centre) and enamel (right) of the giraffe revealed key information about the rate and pattern of dental growth in this vertebrate. These results were also useful to obtain data on the biology and life history of the species and sets the stage for future palaeohistological analysis in ...

Occipital bone modeling patterns during the first years of life: A preliminary histological and quantitative approach

open access: yesJournal of Anatomy, EarlyView.
Modeling maps of the endocranial surface. Orange color indicates resorption fields, blue color deposition. Dashed lines indicate that the pars lateralis and pars basilaris have not yet fused. Abstract Studies of modeling processes have provided important insights in human evolutionary discipline.

Lungfish‐like antero‐labial tooth addition and amphibian‐like enameloid‐enamel transition in the coronoid of a Devonian stem actinopterygian

open access: yesJournal of Anatomy, EarlyView.
The tooth patterning logic, which cannot be inferred from surface morphology, is revealed by visualizing buried tooth remnants in 3D. The primary teeth are added labially, initially organized in radial rows, which transition into linear rows where the coronoid becomes slender.

Skull morphology and histology indicate the presence of an unexpected buccal soft tissue structure in dinosaurs

open access: yesJournal of Anatomy, EarlyView.
A combined approach of osteology and histology was used to examine the cheek regions of dinosaurs. Strong evidence was found for a soft tissue in this region connecting the zygoma to the mandible, here named the ‘exoparia’. Abstract Unlike mammals, reptiles typically lack large muscles and ligaments that connect the zygoma to the mandible.
