Characterization of the extracellular matrix from human and dog umbilical cords

open access: yesThe Anatomical Record, EarlyView.
Abstract The extracellular matrix is important for maintaining tissue morphogenesis and homeostasis; it can also be used as a biomaterial for the production of biological scaffolds. Particularly, the umbilical cord has shown potential in the production of scaffolds for small‐diameter vessels.

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

open access: yesBiotechnology 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

Hyperbranched poly‐L‐lysine surface‐engineered bioprosthetic heart valves with anti‐calcification, anti‐infection, and durability

open access: yesBMEMat, EarlyView.
The challenges of bioprosthetic heart valves (BHV) with respect to calcification, infection, and poor durability are tackled by surface engineering of hyperbranched poly‐L‐lysine (HBPL), providing a translational solution to improve long‐term valve performance.
