SILAC Proteomics of Planarians Identifies Ncoa5 as a Conserved Component of Pluripotent Stem Cells

open access: yesCell Reports, 2013
Planarian regeneration depends on the presence of pluripotent stem cells in the adult. We developed an in vivo stable isotope labeling by amino acids in cell culture (SILAC) protocol in planarians to identify proteins that are enriched in planarian stem ...

Embryonic Stem Cell Research as an Ethical Issue: On the Emptiness of Symbolic Value [PDF]

open access: yes, 2001
The debate over human embryonic stem cell research-scientific and clinical prospects as well as ethical implications-became front-page news only after two teams of university researchers reported in November 1998 that they had isolated and cultured human

Engineering human pluripotent stem cells into a functional skeletal muscle tissue

open access: yesNature Communications, 2018
The generation of functional skeletal muscle tissues from human pluripotent stem cells (hPSCs) has not been reported. Here, we derive induced myogenic progenitor cells (iMPCs) via transient overexpression of Pax7 in paraxial mesoderm cells differentiated

A Human Kidney Tubuloid Model of Repeated Cisplatin‐Induced Cellular Senescence and Fibrosis for Drug Screening

open access: yesAdvanced Healthcare Materials, EarlyView.
Replicating aging and senescence‐related pathophysiological responses in kidney organoids remains a significant challenge. Human adult renal tubular organoid, tubuloids, are successfully developed recapitulating cellular senescence that is the central pathophysiological mechanism of chronic kidney disease (CKD).

Pluripotent Stem Cells: Current Understanding and Future Directions

open access: yesStem Cells International, 2016
Pluripotent stem cells have the ability to undergo self-renewal and to give rise to all cells of the tissues of the body. However, this definition has been recently complicated by the existence of distinct cellular states that display these features ...

Induction of Nephron–Ductal Dual Lineages via Early Retinoic Acid Signaling Establishes a Platform for Fully Patterned Kidney Organoids

open access: yesAdvanced Healthcare Materials, EarlyView.
A simplified, co‐culture‐free protocol for kidney organoids that generate segmented nephrons, including collecting ducts, has been developed. Early low‐dose RA with FGF9 induces balanced anterior–posterior IM patterning and dual UE/MM lineage commitment. BMP7 enhances nephron progenitor maturation.

The transcriptome of human pluripotent stem cells

open access: yesCurrent Opinion in Genetics & Development, 2014
Human Embryonic Stem Cells (hESCs) are in vitro derivatives of the inner cell mass of the blastocyst and are characterized by an undifferentiated and pluripotent state that can be perpetuated in time, indefinitely. hESCs provide a unique opportunity to both dissect the molecular mechanisms that are predisposed to the maintenance of pluripotency and ...

An Innovative “Tooth‐On‐Chip” Microfluidic Device Emulating the Structure and Physiology of the Dental Pulp Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
This work presents a “tooth‐on‐chip” device that mimics dental pulp tissue. By co‐culturing key cell types, it recreates vascular networks, stem cell niches, the odontoblast/dentine interface, and trigeminal innervation. This innovative platform provides a unique model of dental pulp structure and physiology, with significant potential for accelerating
