Cell Adhesion by Design: Engineering Tissue Culture Scaffolds With Adhesion Cues

Advanced Materials Interfaces, EarlyView.
ABSTRACT In scaffold‐based tissue engineering, the matrix should provide adequate adhesion cues for cell attachment, spreading, and function. Given the multitude of adhesion receptors and the diversity of scaffolds, there are many approaches to render scaffolds adhesive, even though they are not all equivalent.

A Case of Transparent Cornea Maintained after Removal of Dislocated Graft from Descemet’s Stripping Automated Endothelial Keratoplasty

Case Reports in Ophthalmology
Introduction: Corneal graft detachment is a major postoperative complication of Descemet’s stripping automated endothelial keratoplasty (DSAEK). When a corneal graft becomes detached, corneal endothelial function generally fails, and repeat corneal ...

Clear corneal grafts with subcritical endothelial cell count after 1 year of penetrating keratoplasty

TNOA Journal of Ophthalmic Science and Research, 2018
Endothelial cell loss after penetrating keratoplasty leads to graft failure. The critical limit of the endothelial cell count for corneal decompensation is thought to be 700 cells/mm2.
