Mesenchymal Stem Cell‐Derived Apoptotic Micro‐Vesicles Repaired Sciatic Nerve Defect by Regulating Early Inflammatory Microenvironment and Promoting Angiogenesis

Advanced Healthcare Materials, EarlyView.
HUCMSC‐Apo‐mvs enhance peripheral nerve repair by modulating the inflammatory microenvironment (IME), primarily through coordinated actions on three functional cells. They recruit macrophages and promote their polarization from pro‐inflammatory M1 to anti‐inflammatory M2 phenotypes, increasing secretion of IL‐10 and VEGF.

A Principal Component Analysis (PCA)-based framework for automated variable selection in geodemographic classification

Geo-spatial Information Science, 2019
A geodemographic classification aims to describe the most salient characteristics of a small area zonal geography. However, such representations are influenced by the methodological choices made during their construction.

Triazine‐Trione Thermosets with High Processability for Scaffold Applications in Bone Tissue Engineering

Advanced Healthcare Materials, EarlyView.
Novel photo‐clickable triazine‐trione thermosets can be shaped and cured under mild conditions, including room and physiological temperatures. These materials are biocompatible and support osteogenic differentiation of bone marrow–derived mesenchymal stem cells on their surface.

Isolation Defines Identity: Functional Consequences of Extracellular Vesicle Purification Strategies

Advanced Healthcare Materials, EarlyView.
Four extracellular vesicle purification strategies are compared using ovarian‐cancer ascites and ES‐2 cell supernatants. A novel workflow links purification to function by combining particle‐normalized proteomics with matched cell‐free and cell‐based assays.

Tutorial: Principal Components Analysis (PCA) in R

, 2010
Found this tutorial by Emily Mankin on how to do principal components analysis (PCA) using R. Has a nice example with R code and several good references. The example starts by doing the PCA manually, then uses R's built in prcomp() function to do the same PCA.

Low‐Temperature Fabrication of Thymosin β4‐Loaded Soluble Microneedles to Promote Wound Healing by Specific Binding to Downregulated Immune Regulators Vsig4 and IL22rɑ2

Advanced Healthcare Materials, EarlyView.
Schematic diagram depicting the fabrication and application of thymosin β4 (Tβ4)‐loaded microneedle patches for wound treatment. The Tβ4 was loaded into chitosan (CS) and sucrose MNs under mild conditions (4°C, 65% relative humidity). The Tβ4 MN patch specifically binds to the downregulated immune regulators Vsig4 and IL22rα2, thereby accelerating ...
