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

open access: yesAdvanced 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.

3D Bioprinting‐Assisted Engineering of Stem Cell‐Laden Hybrid Biopatches With Distinct Geometric Patterns Considering the Mechanical Characteristics of Regular and Irregular Connective Tissues

open access: yesAdvanced Healthcare Materials, EarlyView.
A hybrid biopatch platform integrating 3D printed polymeric patterns with stem cell‐laden collagen bioinks is developed to mimic the mechanical properties of connective tissues. By tailoring geometric architectures, the constructs replicate anisotropic or isotropic mechanics, enhancing tissue‐specific regeneration.

Geometrically Controlled WNT Activation Drives Intestinal Morphogenesis

open access: yesAdvanced Healthcare Materials, EarlyView.
Crypt‐villi‐like morphogenesis can be driven and controlled via architectural patterns in colorectal cells with the use of digital light processing printing. The resulting mini tissues exhibit budding structures and functionality, as evidenced by increased mucin expression.

Biomimetic Scaffolds with Dual Gradients of Biological Effectors for Tendon‐to‐Bone Repair

open access: yesAdvanced Healthcare Materials, EarlyView.
The authors have developed a biomimetic scaffold with dual gradients through a diffusion‐driven method. The scaffold features funnel‐shaped microchannels for cell infiltration, while the dual gradients synergetically induce the graded differentiation of mesenchymal stem cells into osteoblasts, chondrocytes, and tenocytes, allowing for a seamless ...

Development of a Modular Ribonucleoprotein Complex as a General Strategy to Deliver RNAi Therapeutics

open access: yesAdvanced Healthcare Materials, EarlyView.
A modular and customizable RNAi therapeutics delivery platform composed of a pseudosymmetric human RNA binding protein‐siRNA complex (SmiRNP) is developed. By fusing a targeting module and an endosomal escape peptide onto the delivery platform, SmiRNP successfully delivered siRNA to silence the KRAS oncogene in a colorectal carcinoma cell line, leading

Vascularized and Perfusable Human Heart‐on‐a‐Chip Model Recapitulates Aspects of Myocardial Ischemia and Enables Analysis of Nanomedicine Delivery

open access: yesAdvanced Materials, EarlyView.
This novel 3D human ischemic heart‐on‐a‐chip, with perfusable vasculature directly interfaced with myocardial tissue, replicates key aspects of ischemic heart injury. It also demonstrates the targeted delivery and therapeutic efficacy of cardiac homing peptide‐conjugated liposomes, validating the platform for drug and nanomedicine screening in ...
