Role of soft tissue and bone interactions in the developmental integration and modularity of the skull in neural crest‐specific gap junction alpha‐1 knockout mice

open access: yesThe Anatomical Record, EarlyView.
Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

2D copper nanozyme patches facilitate bone regeneration via interfacial modulation of osteoclast‐osteoblast dynamics

open access: yesBMEMat, EarlyView.
This study develops a nano‐enzyme patch (ezPatch) targeting bone interfaces. Utilizing ligand‐to‐metal charge transfer (LMCT) catalysis and bone‐targeting ligands on copper nanosheets, ezPatch simultaneously scavenges reactive oxygen species (ROS) and generates oxygen in situ at bone‐losing sites.

Optimized micro‐sized cell sphere‐matrix niche co‐aggregates promote efficient oral and craniomaxillofacial bone regeneration

open access: yesBMEMat, EarlyView.
The construct of cell‐niche co‐aggregates (GelMA‐SHED sphere‐DDMPs) promotes cranial and periodontal bone regeneration and ensures angiogenic‐osteogenic coupling by downregulating miR‐34c‐5p to enhance the expression of NOTCH1 and its intracellular domain (NICD).

Programmable three‐state nanoreactor for spatiotemporally controlled tumor therapy

open access: yesBMEMat, EarlyView.
The OMVs are shielded with a biocompatible Da–Ca shell, which prolongs its circulation period and promotes intratumoral accumulation. Importantly, the biocompatible Da–Ca shell can be controllably disintegrated in tumor microenvironment by using laser irradiation, generating in situ hyperthermia and releasing Ca2+.

Caveolin‐1 enriched apoptotic bodies derived from oral hard palate orchestrate bone remodeling to treat heterotopic ossification

open access: yesBMEMat, EarlyView.
Downregulated CAV1 in HO is restored via apoptotic bodies from PMSCs, which reprogram bone remodeling by delivering CAV1 to target cells, highlighting the therapeutic role of EV subtypes in heterotopic ossification. Abstract Heterotopic ossification (HO) is a pathological process characterized by ectopic bone formation in non‐osseous tissues, with an ...

Glass eels and viruses – a lesson learnt from stocking the eastern German Baltic Sea coast

open access: yesTransboundary and Emerging Diseases, Accepted Article., 2022
Abstract Concerns about Anguillid herpesvirus 1 (AngHV‐1) in European eels, especially due to stocking measures, is increasingly coming into focus and raises questions regarding disease monitoring and prevention. In the past, stocking of AngHV‐1‐positive eels into waters assumed AngHV‐1‐free has led to a rapid increase of infected eels in the wild. For

Multifunctional polycaprolactone‐based composite fibers with icariin and glutathione for effective repair of critical‐sized bone defects

open access: yesBMEMat, EarlyView.
A multifunctional PCL‐based scaffold co‐delivering Icariin and Glutathione synergistically enhances osteogenesis, angiogenesis, and oxidative stress resistance, achieving near‐complete repair of critical‐sized bone defects in vivo. This cell‐free platform represents a promising strategy for accelerated bone regeneration.

Nacre‐inspired layered composite with excellent mechanical support and osteogenic potential for cervical interbody cage

open access: yesBMEMat, EarlyView.
The cervical interbody cage needs to take both biomechanical and biological requirements into account. Here, a new‐style degradable, multicomponent, and bioinspired nacre‐like cervical interbody cage composite, which exhibits promising mechanical‐support‐related behavior and osteogenesis‐related potential, is designed and prepared.
