Epidermis and epithelia lining the ocular surface, the oral cavity, the pharynx, the oesophagus, the larynx, and the vagina, called stratified squamous epithelia (SSE), contain stem/progenitor cells that support renewal and repair. Under appropriate condit ...

The functional analysis of Lrig1 in the mouse cornea

Andrea Zaffalon

Regenerative medicine aims to recreate functional tissues in vitro for the regeneration of damaged organs and solve the dramatic problem of transplant rejection. Cornea integrity is primordial for our vision. Several therapies to regenerate healthy corneal ...

Corneal diseases account for eight million blind people worldwide, making up to 10% of all causes of blindness. As 80% of the information is collected by our senses, blindness is a very invalidating condition which lowers greatly patients’ quality of life. ...

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 ...

Nowadays the mechanism regulating the corneal epithelium renewal still remains unclear. Until now it was thought to be the fact of stem cells distributed in the limbus, generating TA cells migrating towards the central cornea and responsible for its renewa ...

A novel approach for the isolation of mesenchymal stem cells

Mesenchymal stem cells (MSC) are a population of multipotent cells that can differentiate into various lineages such as fibroblast, osteoblast, chondrocyte and adipocyte and can be maintained over extended periods in vitro. They are also known to have a su ...

Bioengineering stem cell niches in 2D and 3D

Nora Leonardi

Muscle degenerative disorders, such as Duchenne muscular dystrophy, have a profound impact on the quality of life and survival of patients. Transplantation of myoblasts to restore muscle function has been discouraging since these cells die and don't migrat ...

Muscle stem cell's in vitro bipolar niche

Adrien de Tonnac

In the domain of regenerative medicine research there are many fronts aimed at increasing our understanding of induced pluripotent, embryonic and adult stem cells. Recently a new front has appeared, stem cell niches, the microenvironment that is a crucial ...

The role of CITED2 in human embryonic stem cells

Human embryonic stem (hES) cells can self-renew in culture and differentiate into cells of all three germ layers. Identification of regulators of the self-renewal versus differentiation decisions in hES cells will facilitate manipulation of these cells. Se ...
