Basal keratinocytes contribute to all strata of the adult zebrafish epidermis. [PDF]

PLoS ONE, 2014
The epidermis of terrestrial vertebrates is a stratified epithelium and forms an essential protective barrier. It is continually renewed, with dead corneocytes shed from the surface and replaced from a basal keratinocyte stem cell population.

Epidermal stem cells: Properties, markers, and location [PDF]

Proceedings of the National Academy of Sciences, 2000
Recent data indicate that stem cells exist in many tissues, including skeletal muscle, liver, and the central nervous system, some of them not known classically as having stem cells. The unexpected plasticity and the tremendous disease implications of these findings have created a lot of excitement (1, 2).

Upregulated sirtuin 1 by miRNA-34a is required for smooth muscle cell differentiation from pluripotent stem cells [PDF]

, 2015
© 2015 Macmillan Publishers Limited. All rights reserved. microRNA-34a (miR-34a) and sirtuin 1 (SirT1) have been extensively studied in tumour biology and longevityaging, but little is known about their functional roles in smooth muscle cell (SMC ...

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

FEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

Stress vesicles link epidermal mechanotransduction to stem cell differentiation

Nature Communications
The skin exhibits extraordinary plasticity, enabling it to adapt to mechanical changes in the environment. While transient deformations are accommodated without lasting structural effects, sustained mechanical stress induces durable tissue changes.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

The species specific effects of Mesenchymal stem cell conditioned medium on proliferating mouse and rat adult neural stem, progenitor cells [PDF]

, 2012
Adult stem cells reside in different tissues and organs of the adult organism. Among these cells are Mesenchymal stem cells (MSCs) and neural stem and progenitor cells (NSPCs).

Spatially Controlled Embedded Bioprinting of Prevascularized Spheroids‐Containing Biopatch Enables Functional Skin Regeneration

Advanced Healthcare Materials, EarlyView.
A spatially controlled embedded bioprinting strategy enables precise engineering of prevascularized multicellular spheroids within skin‐derived dECM bioinks. Optimized spheroid size, composition, and spacing promote vascular maturation, paracrine signaling, and tissue integration, resulting in enhanced angiogenesis, blood perfusion, and functional skin

Making the Case for Organ‐on‐Chip Platforms in Long‐Acting Therapeutics Development

Advanced Healthcare Materials, EarlyView.
LATs release drug from a tissue‐resident depot over weeks to months, improving adherence, but their development is hampered by preclinical models that cannot reproduce the coupled tissue processes, sustained release, local microenvironment change, interstitial transport, immune and foreign‐body responses, and clearance that govern depot performance in ...
