Abstract A key property of the human cornea is to maintain its curvature and consequently its refraction capability despite daily changes in intraocular pressure. This is closely related to the multiscale structure of the corneal stroma, which consis

Epithelial and stromal stem cells are required to maintain corneal transparency. The aim of the study was to develop a new method to isolate and grow both corneal stromal (SSC) and epithelial limbal (LSC) stem cells from small human limbal biopsies u

BackgroundSecond Harmonic Generation (SHG) microscopy recently appeared as an efficient optical imaging technique to probe unstained collagen-rich tissues like cornea. Moreover, corneal remodeling occurs in many diseases and precise characterization

Les étudiants ont la fierté de construire - de toute pièce - un microscope produisant des images tridimensionnelles (3D) d’objets transparents ou faiblement diffusants. Le projet laisse le temps aux étudiants de progresser en toute autonomie et

Optical coherence tomography, or in short OCT, is a measurement technique established in the early 1990s for the non-invasive imaging of interfaces in the bulk of biological tissues or other samples. A full-field OCT setup is built from a microscope

SHG microscopy is a unique tool for collagen visualization without any staining. Polarimetric approaches based on linear and circular polarizations further provide the orientation of collagen fibrils within and out of the imaging plane and their degr

We implement polarization-resolved second harmonic generation microscopy to characterize the orientation distribution of collagen lamellae in human cornea. We evidence a less ordered distribution in keratoconic corneas, in agreement with their deteri

Second harmonic generation microscopy (SHG) is now the gold standard technique for in situ visualization of unstained fibrillar collagen in intact tissues [1] . Collagen is the most abundant protein in mammals and is found in many tissues, such as ar

Advanced nonlinear optical (NLO) microscopy enables quantitative in situ mapping of parchment degradation at the micrometer scale. We show that measurements of the ratio of fluorescence over second harmonic generation (SHG) signals probes severe coll
