Synthesis and Characterization of Silk Ionomers for Layer-By-Layer Electrostatic Deposition on Individual Mammalian Cells

Through the optimization of material properties and composition of incubation buffers, silk ionomers could be electrostatically assembled on the surface of murine fibroblasts and human mesenchymal stem cells to form nanoscale multilayers without significantly impairing cell viability.

Abstract

Direct Incorporation of Mesenchymal Stem Cells into a Nanofiber Scaffold – In Vitro and In Vivo Analysis

Stem cells isolated from rat femora were incorporated into poly-l-lactide acid (PLLA) and PLLA-collagen type-I nanofiber scaffolds via simultaneous electrospinning and spraying.

Heat Treatment Dependent Cytotoxicity of Silicalite-1 Films Deposited on Ti-6Al-4V Alloy Evaluated by Bone-Derived Cells

Two types of bone-derived cells were used for a biocompatibility assessment. While no increase in cell membrane damage, in ROS generation and in TNF-alpha secretion of bone-derived cells grown on both silicalite-1 films was found.

Human Umbilical Cord Blood-Derived MSC Exosomes Attenuate Myocardial Injury by Inhibiting Ferroptosis in Acute Myocardial Infarction Mice

Overexpression of divalent metal transporter 1 (DMT1) promoted H/R-induced myocardial cell ferroptosis, while knockdown of DMT1 significantly inhibited the ferroptosis.

Abstract

Canonical Notch Signaling Is Required for Bone Morphogenetic Protein‐Mediated Human Osteoblast Differentiation

Systemic Notch inhibition using diabenzazepine reduced bone morphogenetic protein (BMP)2-induced calvarial bone healing in mice supporting the critical regulatory role of Notch signaling in BMP-induced osteoblastogenesis.

Abstract

Bobby Sox Homolog Regulates Tooth Root Formation through Modulation of Dentin Sialophosphoprotein

Investigators generated bobby sox homolog (Bbx) knockout mice to address the functional role of Bbx in tooth formation. During tooth development, Bbx was expressed in both dental epithelium and mesenchyme.

Abstract

Bushenhuoxue Formula Accelerates Fracture Healing via Upregulation of TGF-β/Smad2 Signaling in Mesenchymal Progenitor Cells

Researchers performed unilateral open transverse tibial fracture procedure in C57BL/6 mice which were treated with or without Bushenhuoxue formula.

Gaucher Disease-Associated Alterations in Mesenchymal Stem Cells Reduce Osteogenesis and Favor Adipogenesis Processes with Concomitant Increased Osteoclastogenesis

Researchers evaluated the process of osteoclastogenesis and observed that conditioned media from Gaucher disease MSCs supernatants induced an increase in the number of osteoclasts.

REVIEWS

Skull Base Chordomas and Chondrosarcomas

Chordomas and chondrosarcomas are not sensitive to chemotherapy and there are no approved drugs for their treatment. The present treatment concept is a combination of surgical resection with a maximal excision and preserving patients’ quality of life by adjuvant radiotherapy for both, chordomas and chondrosarcomas.

Hong Kong’s Contentious National Security Law Concerns Some Academics

China’s plan to introduce a new security law in Hong Kong has prompted mixed reactions from scientists there. Some fear that such a law could lead to government interference in research, restrict participation in international collaborations and increase self-censorship, whereas others are confident that research will be unaffected.
