Extracellular Vesicles‐Based Biological Macromolecule Delivery Systems: Biogenesis, Characterization, and Emerging Clinical Applications

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are nanoscale membrane‐bound structures that play a pivotal role in intercellular communication by transporting bioactive molecules, including proteins, lipids, nucleic acids, and organelles, between cells. Originating from the endosomal pathway, EVs reflect the physiological and pathological status of their parent

A stepwise mode of TGFβ-SMAD signaling and DNA methylation regulates naïve-to-primed pluripotency and differentiation

Nature Communications
The formation of transcription regulatory complexes by the association of Smad4 with Smad2 and Smad3 (Smad2/3) is crucial in the canonical TGFβ pathway.

Smad2/3 Upregulates the Expression of Vimentin and Affects Its Distribution in DBP-Exposed Sertoli Cells

PPAR Research, 2015
Sertoli cells (SCs) in the testes provide physical and nutritional support to germ cells. The vimentin cytoskeleton in SCs is disrupted by dibutyl phthalate (DBP), which leads to SCs dysfunction. In a previous study, we found that peroxisome proliferator-

Smad2 and Smad3 coordinately regulate craniofacial and endodermal development

Developmental Biology, 2004
Ligands of the transforming growth factor-beta (TGF-beta) superfamily are involved in numerous developmental and disease processes. TGF-beta, activins, and nodal ligands operate through the highly homologous Smad2 and Smad3 intracellular mediators. Smad2 mutants exhibit early embryonic lethality, while Smad3 mutants are viable, but show a plethora of ...

Differential sensitivity to SHH signaling and neural crest‐mediated Gas1 expression regulate jaw size during development and evolution

Developmental Dynamics, EarlyView.
Abstract Background Developmental control of jaw size is crucial to prevent birth defects and facilitate evolutionary adaptation. We have shown that jaw size is established by neural crest mesenchyme (NCM), which are progenitor cells that migrate into the mandibular primordia and produce the jaws.
