Clearing the Path for Germ Cells [PDF]

Cell, 2008
The chemokine SDF-1a and its receptor CXCR4b guide germ cell migration in zebrafish by activating downstream signaling events. Boldajipour et al. (2008) now report that a second SDF-1a receptor, CXCR7, is also required for guided migration but does not function as a signaling receptor, and instead sequesters SDF-1a.

Machine Learning‐Enabled Polymer Discovery for Enhanced Pulmonary siRNA Delivery

Advanced Functional Materials, EarlyView.
This study provides an efficient approach to train a machine learning model by merging heterogeneous literature data to predict suitable polymers for siRNA delivery. Without the need for extensive laboratory synthesis, the machine learning enabled a virtual screening and successfully predicted a polymer that is validated for effective gene silencing in

High‐Throughput Microfluidic‐Mediated Assembly of Layer‐By‐Layer Nanoparticles

Advanced Functional Materials, EarlyView.
The layer‐by‐layer (LbL) assembly of polymer films on nanoparticle (NP) surfaces is a promising technique for targeted drug delivery. Despite its success in preclinical mouse models, a current good manufacturing practices (cGMP) compliant, clinical‐scale production method has been lacking.

DNMTs and SETDB1 function as co-repressors in MAX-mediated repression of germ cell-related genes in mouse embryonic stem cells. [PDF]

PLoS ONE, 2018
In embryonic stem cells (ESCs), the expression of development-related genes, including germ cell-related genes, is globally repressed. The transcription factor MAX represses germ cell-related gene expression in ESCs via PCGF6-polycomb repressive complex ...

GASZ promotes germ cell derivation from embryonic stem cells [PDF]

, 2013
Primordial germ cells (PGCs) are the first germ-line population that forms from the proximal epiblast of the developing embryo. Despite their biological importance, the regulatory networks whereby PGCs arise, migrate, and differentiate into gametes ...

Perfusable Brain Microvascular Network‐On‐Chip Model to Study Flavivirus NS1‐Induced Endothelial Dysfunction

Advanced Functional Materials, EarlyView.
This study presents a microfluidic brain microvascular network‐on‐chip (BMVasChip) to investigate endothelial barrier dysfunction caused by flavivirus non‐structural protein 1 (NS1), including virus‐ and time‐dependent vascular damage, leakiness, and dysfunction.

Germ Cell-less Promotes Centrosome Segregation to Induce Germ Cell Formation

Cell Reports, 2017
The primordial germ cells (PGCs) specified during embryogenesis serve as progenitors to the adult germline stem cells. In Drosophila, the proper specification and formation of PGCs require both centrosomes and germ plasm, which contains the germline ...

Unlock the Walnut: How a Pectin‐Rich Suture Tissue and Moisture‐Driven Crack Formation Induce Shell Splitting and Facilitate Seed Germination

Advanced Functional Materials, EarlyView.
Walnut seeds are enclosed in a remarkably strong shell made of sclerenchyma, separated by a pectin‐rich suture tissue. Different cell shapes and chemical composition of this tissue point to an opening mechanism, which is triggered by cyclic humidity changes.

A nucleic acid binding protein map of germline regulation in Caenorhabditis elegans

Nature Communications
Fertility requires the faithful proliferation of germ cells and their differentiation into gametes. Controlling these cellular states demands precise timing and expression of gene networks. Nucleic acid binding proteins (NBPs) play critical roles in gene
