Sharpening our understanding of saber‐tooth biomechanics

open access: yesThe Anatomical Record, EarlyView.
Abstract Saber‐teeth are a striking example of convergent evolution in vertebrate predators, having evolved multiple times in mammals and their early ancestors. While there is broad consensus that saber‐toothed taxa employed a distinct biting strategy compared to conical‐toothed carnivores, like the lion, the precise mechanics and variability of this ...

China shares fossil treasures with the world

open access: yesThe Anatomical Record, EarlyView.
Abstract China has been a rich source of fossils for nearly a century, beginning with the discovery of so‐called Peking man (Sinanthropus pekinensis), known today as Homo erectus pekinensis in the mid 1920s. The first Chinese dinosaurs were described in 1929, the sauropod Helopus (now Euhelopus) and the ornithopod Tanius, described by the Swedish ...

Decoding regulatory programs underlying placode and dermal condensate cell fate commitment during hair follicle induction via single‐cell multi‐omics analysis

open access: yesAnimal Research and One Health, EarlyView.
The experimental framework of the study encompasses sample collection, single‐cell data analysis, and experimental validation. Abstract Understanding differences in chromatin state and changes in gene regulatory landscape of placode (Pc) and dermal condensate are crucial for decoding hair follicle (HF) morphogenesis programs.

Dynamic Compression Improves Chondrogenesis in the Tissue Engineered Model of Cartilage

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Hyaline cartilage is a dense avascular tissue with low regenerative potential, present at the ends of the diarthrodial joints and in the cartilage growth plate. Skeletal diseases often result from extracellular changes in this tissue; however, studies of these are hindered by the tissue complexity, the difficulty in obtaining human material ...

Phosphorylation at the Helm: Kinase‐Mediated Regulation of Primary Cilia Assembly and Disassembly

open access: yesCytoskeleton, EarlyView.
ABSTRACT The primary cilium serves as an antenna of most vertebrate cells and is important for conveying cues from several signaling pathways into appropriate cellular responses during development and homeostasis. Cilia assembly and disassembly processes are thought to be strictly controlled; however, the precise nature of molecular events underlying ...

Dynamics of primary cilia in endothelial and mesenchymal cells throughout mouse lung development

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Cilia are specialized structures found on a variety of mammalian cells, with variable roles in the transduction of mechanical and biological signals (by primary cilia, PC), as well as in the generation of fluid flow (by motile cilia). Their critical role in the establishment of a left–right axis in early development is well described, as well ...

The role of the PTHrP/Ihh feedback loop in the unusual growth plate location in mammalian metatarsals and pisiforms

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Longitudinal skeletal growth takes place in the cartilaginous growth plates. While growth plates are found at either end of conventional long bones, they occur at a variety of locations in the mammalian skeleton. For example, the metacarpals and metatarsals (MT) in the hands and feet form only a single growth plate at one end, and ...

A head start: The relationship of placental factors to craniofacial and brain development

open access: yesDevelopmental Dynamics, EarlyView.
Abstract In recent years, the importance of placental function for fetal neurodevelopment has become increasingly studied. This field, known as neuroplacentology, has greatly expanded possible etiologies of neurodevelopmental disorders by exploring the influence of placental function on brain development.

The endocannabinoid system regulates both ependymoglial and neuronal cell responses to a tail amputation in the axolotl

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The endocannabinoid system is a neuromodulatory system implicated in cellular processes during both development and regeneration. The Mexican axolotl, one of only a few vertebrates capable of central nervous system regeneration, was used to examine the role of the endocannabinoid system in the regeneration of the tail and spinal ...
