Heparin affinity purification of extracellular vesicles

Scientific Reports, 2015
Extracellular vesicles (EVs) are lipid membrane vesicles released by cells. They carry active biomolecules including DNA, RNA and protein which can be transferred to recipient cells. Isolation and purification of EVs from culture cell media and biofluids

Suppressing t(4;11) Acute Leukemia by Lipopolymer Nanoparticle Delivery of siRNA Targeting KMT2A::AFF1 with Enhanced Extrahepatic Delivery

Advanced Healthcare Materials, EarlyView.
This study introduces a new lipopolymer nanoparticle (LPNP) system that efficiently delivers siRNA to leukemia cells. The LPNPs silence the leukemia fusion gene KMT2A::AFF1, induce apoptosis, and decrease leukemia burden in mice. These results demonstrate the potential of LPNPs as a targeted siRNA therapy for acute lymphoblastic leukemia.

Programmable Compliance in Small‐Diameter Vascular Grafts by Design of Melt‐Electrowritten Scaffold Architectures for In Situ Tissue Engineering

Advanced Healthcare Materials, EarlyView.
Small‐diameter vascular grafts with compliance tunable by design are fabricated via melt electrowriting. By controlling the winding angle of intertwined helical fibers, grafts with compliances matching those of human vessels, from veins to arteries, are realized. This holds the potential of avoiding a compliance mismatch, which has been identified as a

Induction of Nephron–Ductal Dual Lineages via Early Retinoic Acid Signaling Establishes a Platform for Fully Patterned Kidney Organoids

Advanced Healthcare Materials, EarlyView.
A simplified, co‐culture‐free protocol for kidney organoids that generate segmented nephrons, including collecting ducts, has been developed. Early low‐dose RA with FGF9 induces balanced anterior–posterior IM patterning and dual UE/MM lineage commitment. BMP7 enhances nephron progenitor maturation.

Heparin releases newly synthesized cell surface-associated apolipoprotein E from HepG2 cells.

Journal of Lipid Research, 1993
Heparin significantly increased the amount of newly synthesized apolipoprotein E (apoE) released by HepG2 cells. Culturing cells in the presence of 10 micrograms/ml of heparin for 2-6 days caused a 1.3-fold (day 2) to 3-fold (day 6) increase of ...

A Modular Perfusion Bioreactor Platform for Simulating Bone Regeneration and Fracture Healing: Integrating Mechanical Loading and Dual Perfusion for Advanced In Vitro Models

Advanced Healthcare Materials, EarlyView.
A modular bioreactor platform was developed in order to replicate bone homeostasis and pathology, thereby integrating mechanical loading, dynamic perfusion, and a 3D‐printed microfluidic chamber. With precise control of environmental parameters and dual perfusion for composite tissue models, the system enhances physiological relevance for studying bone
