Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

FEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

FEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

PI3K/Akt1 signalling specifies foregut precursors by generating regionalized extra-cellular matrix

eLife, 2013
During embryonic development signalling pathways act repeatedly in different contexts to pattern the emerging germ layers. Understanding how these different responses are regulated is a central question for developmental biology.

Tissue‐Stimulator Platform for Electrically Stimulating Pancreatic β‐Cells for Long‐Term Functional Regulation

Advanced Functional Materials, EarlyView.
We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

In vitro Symbiosis of Reef-Building Coral Cells With Photosynthetic Dinoflagellates

Frontiers in Marine Science, 2021
Coral reefs are the biodiversity hot spots of the oceans, but they have suffered from increasing environmental stresses caused principally by anthropogenic global warming.

ELABELA Targets Mitochondria to Modulate Heart Development

Advanced Science, EarlyView.
The role of peptide ELABELA (ELA) in cardiomyocyte apoptosis and congenital heart disease (CHD) is unclear. ELA deficiency caused cardiomyocyte apoptosis and CHD. A novel ELA‐APJ‐AKT‐BCL2/BAX axis in regulating mitochondrial function and contributing to CHD pathogenesis was established.

Effect of Hepatic Differentiation on Fatty Acid Composition of Induced Pluripotent Stem Cells Derived from Human Dermal Fibroblasts

İstanbul Medical Journal, 2018
Introduction: Human induced pluripotent stem cells (hiPSCs) have been recognized as key progenitor cells for liver regeneration, which could potentially be used in the repair of liver injury.

Conformable Microelectrode Arrays Integrated with a Scoop‐Shaped Slide‐Well for Dynamic Electrophysiological Profiling of Patient‐Derived Cardiac Organoids

Advanced Science, EarlyView.
A flexible, ultrathin multi‐channel microelectrode array (MEA) conformally integrated onto a curved slide‐well enables stable electrical interfacing with 3D cardiac organoids. The geometry‐guided self‐alignment allows simultaneous recording of extracellular field potentials and contractile motion from irregular, beating tissues.

Vg1-Nodal heterodimers are the endogenous inducers of mesendoderm

eLife, 2017
Nodal is considered the key inducer of mesendoderm in vertebrate embryos and embryonic stem cells. Other TGF-beta-related signals, such as Vg1/Dvr1/Gdf3, have also been implicated in this process but their roles have been unclear or controversial.
