In situ detection of multitarget impurities on contact lens by electrochemical scanning probe

Identifying multitarget impurities on contact lenses is challenging because traditional methods such as polymerase chain reaction cannot be used on the unknown target. Other sampling methods often require expensive antibodies or dyes. Therefore, this resea ...

Cyclodextrin Modulated Type I Collagen Self-Assembly to Engineer Biomimetic Cornea Implants

Francesco Stellacci, Evangelia-Nefeli Athanasopoulou

Collagen-rich tissues in the cornea exhibit unique and highly organized extracellular matrix ultrastructures, which contribute to its high load-bearing capacity and light transmittance. Corneal collagen fibrils are controlled during development by small le ...

Corneal epithelial stem cells and their niche at a glance

Freddy Radtke, Craig Nowell

The corneal epitheliumacts as a protective barrier on the anterior ocular surface and is essential for maintaining transparency of the cornea and thus visual acuity. During both homeostasis and repair, the corneal epithelium is maintained by self-renewing ...

Chronic inflammation imposes aberrant cell fate in regenerating epithelia through mechanotransduction

Freddy Radtke, Matthias Lütolf, Yann Barrandon, Georg Fantner, Sylke Höhnel, Pascal Damian Odermatt, Craig Nowell, Luca Azzolin

Chronic inflammation is associated with a variety of pathological conditions in epithelial tissues, including cancer, metaplasia and aberrant wound healing. In relation to this, a significant body of evidence suggests that aberration of epithelial stem and ...

Capturing epidermal stemness

Andrea Zaffalon

Regenerative medicine aims to replace or regenerate tissues or organs to re-establish their normal function. In 1975, Rheinwald and Green developed a technique to isolate and amplify epidermal stem cells. Their discovery led to the development of cultured ...

Innovative strategy of corneal epithelium regeneration using fabricated soft contact lens containing cavities for stem cells transplantation

Julien Graber

Transplantation of donor cornea is widely performed with a high success rate to treat patients with impaired corneal transparency. However the limited number of donors has led scientists to search for new technologies and treatments, including stem cell th ...

Enrichment of pathogenic alleles in the brittle cornea gene, ZNF469, in keratoconus

Keratoconus, a common inherited ocular disorder resulting in progressive corneal thinning, is the leading indication for corneal transplantation in the developed world. Genome-wide association studies have identified common SNPs 100 kb upstream of ZNF469 s ...

Corneal Endothelial Cell Fate Is Maintained by LGR5 Through the Regulation of Hedgehog and Wnt Pathway

Yann Barrandon

Leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5), a target of Wnt signaling, is reportedly a marker of intestine, stomach, and hair follicle stem cells in mice. To gain a novel insight into the role of LGR5 in human corneal tissue, we per ...

Essential Role for Pbx1 in Corneal Morphogenesis

PURPOSE. The Pbx TALE (three-amino-acid loop extension) homeodomain proteins interact with class 1 Hox proteins, which are master regulators of cell fate decisions. This study was performed to elucidate the role of the Pbx1 TALE protein in the corneal epit ...

Second harmonic generating (SHG) Nanoprobes: A new tool for biomedical imaging

Demetri Psaltis, Ye Pu, Ye Pu

Cornea functions as an outermost lens and plays an important role in vision. For cornea diagnosis and treatment, a microscopic imaging system with cellular resolution and high eye safety is strongly desired. Recently, the cell morphology of corneal epithel ...
