Generation of an expandable intermediate mesoderm restricted progenitor cell line from human pluripotent stem cells. [PDF]

open access: yes, 2015
The field of tissue engineering entered a new era with the development of human pluripotent stem cells (hPSCs), which are capable of unlimited expansion whilst retaining the potential to differentiate into all mature cell populations.

Control of intestinal stem cell function and proliferation by mitochondrial pyruvate metabolism. [PDF]

open access: yes, 2017
Most differentiated cells convert glucose to pyruvate in the cytosol through glycolysis, followed by pyruvate oxidation in the mitochondria. These processes are linked by the mitochondrial pyruvate carrier (MPC), which is required for efficient ...

A Physiological Microfluidic Blood–Brain‐Barrier Model for In Vitro Study of Nanoparticle Trafficking and Accumulation

open access: yesAdvanced Healthcare Materials, EarlyView.
A human microfluidic blood‐brain barrier (mBBB) model enables spatially resolved comparison of nanoparticle trafficking. Extracellular vesicles (EVs), liposomes, and nanoplastics exhibit distinct transport and disruption behaviors, revealing that membrane composition and uptake pathways govern BBB interaction.

Brain organoids and genome editing: A new era in understanding human brain development and disorders

open access: yesNeural Regeneration Research
Brain organoids are artificial neural tissues derived in vitro, containing a variety of cell types, as well as structural and/or functional brain regions. They can partially mimic brain physiological activities and diseased processes.
