Journal ArticleDOI
Structural Interactions between Collagen and Proteoglycans Are Elucidated by Three-Dimensional Electron Tomography of Bovine Cornea
Philip N. Lewis,Christian Pinali,Robert D. Young,Keith M. Meek,Andrew J. Quantock,Carlo Knupp +5 more
TL;DR: The first three-dimensional electron microscopic reconstructions of the cornea are presented, and it is proposed that the characteristic pseudohexagonal fibril arrangement in cornea is controlled by the balance of a repulsive force arising from osmotic pressure and an attractive force due to the thermal motion of the proteoglycans.
Journal ArticleDOI
Biomaterials-enabled cornea regeneration in patients at high risk for rejection of donor tissue transplantation.
Mohammad Mirazul Islam,Oleksiy Buznyk,Oleksiy Buznyk,Jagadesh C Reddy,Nataliya Pasyechnikova,Emilio I. Alarcon,Sally Hayes,Philip N. Lewis,Per Fagerholm,Chaoliang He,Stanislav Iakymenko,Wenguang Liu,Keith M. Meek,Virender S Sangwan,May Griffith,May Griffith,May Griffith +16 more
TL;DR: It is shown that cell-free implants are potentially safe, efficacious options for treating high-risk patients and a biomaterials-enabled pro-regeneration strategy to restore corneal integrity in an open-label observational study of six patients.
Journal ArticleDOI
Matrix morphogenesis in cornea is mediated by the modification of keratan sulfate by GlcNAc 6-O-sulfotransferase.
Yasutaka Hayashida,Tomoya O. Akama,Nicola Beecher,Philip N. Lewis,Robert D. Young,Keith M. Meek,Briedgeen Kerr,Clare Elizabeth Hughes,Bruce Caterson,Akira Tanigami,Jun Nakayama,Michiko N. Fukada,Yasuo Tano,Kohji Nishida,Andrew J. Quantock +14 more
TL;DR: The corneal stroma of the Chst5-null mouse exhibited widespread structural alterations in collagen fibrillar architecture, including decreased interfibrillsar spacing and a more spatially disorganized collagen array, and the enzymatic sulfation of KS GAG chains is identified as a key requirement for PG biosynthesis and collagen matrix organization.
Book ChapterDOI
The Architecture of the Cornea and Structural Basis of Its Transparency
Carlo Knupp,Christian Pinali,Philip N. Lewis,Geraint J. Parfitt,Robert D. Young,Keith M. Meek,Andrew J. Quantock +6 more
TL;DR: The macromolecular components of the corneal stroma are reviewed, the way they are organized into a stacked lamellar array, and how this organization guarantees Corneal transparency is reviewed.
Journal ArticleDOI
Three-dimensional arrangement of elastic fibers in the human corneal stroma☆
Philip N. Lewis,Tomas White,Robert D. Young,James Stephen Bell,C. Peter Winlove,Keith M. Meek +5 more
TL;DR: It is argued that elastic sheets will play an important role in the biomechanical deformation and recovery of the peripheral cornea and may have practical implications for understanding the structural basis behind a number of corneal surgeries.
