PDCD2 is essential for inner cell mass development and embryonic stem cell maintenance

Developmental Biology, 2010
PDCD2 is a conserved eukaryotic protein implicated in cell cycle regulation by virtue of its interactions with HCFC1 and the NCOR1/SIN3A corepressor complex. Pdcd2 transcripts are enriched in ES cells and other somatic stem cells, and its ortholog is essential for hematopoietic stem cell maintenance in Drosophila. To characterize the physiological role(

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework

Advanced Functional Materials, EarlyView.
The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...

Emerging cooperativity between Oct4 and Sox2 governs the pluripotency network in early mouse embryos

eLife
During the first lineage segregation, mammalian embryos generate the inner cell mass (ICM) and trophectoderm (TE). ICM gives rise to the epiblast (EPI) that forms all cell types of the body, an ability referred to as pluripotency.

Asynchronous fate decisions by single cells collectively ensure consistent lineage composition in the mouse blastocyst

Nature Communications, 2016
Early embryonic cell fate and lineage specification is tightly regulated in the preimplantation mammalian embryo. Here, the authors quantitatively examine the ratio of epiblast to primitive endoderm lineages in the blastocyst and show composition of the ...

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

Advanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

Advanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

PRODUCTION OF EMBBRYONIC STEM CELLS FROM INNER CELL MASS OF BLASTOCYST ISOLATED BY ENZYMATIC AND IMMUNOSURGERY METHODS

Jurnal Veteriner, 2008
The objective of the research is determining the ICM isolation method to produce ESC. Blastocyst stage of DDy mice embryos were used in this study. Zona pellucida of blastocysts were removed by 0.25% pronase, the ICM isolation were done by enzimatic or ...

Fusogenic RNA Nanomodules for Fusion‐Mediated and Multiplexed siRNA Delivery

Advanced Functional Materials, EarlyView.
A fusogenic lipid‐layered RNA nanomodules (L‐CRAMs) enable high‐capacity and long‐lasting siRNA delivery through membrane fusion. These nanomodules carry exceptionally large siRNA payloads, avoid conventional endosomal uptake, and release multiple functional siRNAs through Dicer‐mediated processing.
