Design Principles of Pancreatic Islets: Glucose-dependent Coordination of Hormone Pulses
, 2015 Pancreatic islets are functional units involved in glucose homeostasis. The multicellular system comprises three main cell types; $\beta$ and $\alpha$ cells reciprocally decrease and increase blood glucose by producing insulin and glucagon pulses, while ...

An In Vitro Human Segmentation Clock Model Derived from Embryonic Stem Cells
Cell Reports, 2019 Summary: Defects in somitogenesis result in vertebral malformations at birth known as spondylocostal dysostosis (SCDO). Somites are formed with a species-specific periodicity controlled by the “segmentation clock,” which comprises a group of oscillatory ...

A Novel Approach to Implementing Artificial Thalamic Neurons with Ferroelectric Transistors
Advanced Functional Materials, EarlyView.Artificial neurons created using CMOS technology often require a large number of transistors and capacitors. This study introduces an artificial thalamic neuron that employs only five CMOS compatible ferroelectric transistors. The manufactured thalamic neuron demonstrates leaky integrate‐and‐fire‐or‐burst (LIFB) functionalities, featuring self ...

A case report of a family with developmental arrest of human prokaryotic stage zygote
Frontiers in Cell and Developmental BiologyTo study the genetic variation leading to the arrest phenotype of pronuclear (PN) zygotes. We recruited a family characterized by recurrent PN arrest during in vitro fertilization (IVF) and intracytoplasmic sperm injection cycles (ICSI) and performed ...

Formation of transient lamellipodia. [PDF]
PLoS ONE, 2014 Cell motility driven by actin polymerization is pivotal to the development and survival of organisms and individual cells. Motile cells plated on flat substrates form membrane protrusions called lamellipodia. The protrusions repeatedly appear and retract
