Book Description
The human cornea acts as a protective covering for the eye and plays an important role in light transmission into the eye for vision. Corneal defects due to trauma, infection, or disease can have detrimental effects on the vision, and severe cases lead to vision loss. Twenty-three million people are estimated to be affected by corneal blindness worldwide. Treatment involves corneal transplantation surgery, but there is a severe shortage of donor corneas worldwide. Furthermore, patients with severe pathologies risk rejecting conventional corneal transplantation, thus leaving them untreated. Therefore, there is an urgent need to develop new therapies to replace traditional corneal transplant surgery. This review focuses on recent potential biomaterials development for corneal regeneration and repair. It includes cell-based therapies, cell-free regeneration-inducing biomaterials, and injectable or in-situ gelation-based biomaterials for patients with a high risk of graft failure. It also consists of the emerging role of exosomes and extracellular vesicles in corneal infections and regeneration.

Book Description
This text provides expert instruction on the varying surgical techniques currently employed for the regeneration of the ocular surface. Corneal Regeneration: Therapy and Surgery begins with a thorough discussion of current research based on data obtained in clinical human studies, and discusses the potential clinical implications for this promising new stage of eye surgery. Sections devoted to the stem cell, regenerative surgery and therapy of the ocular surface epithelium, corneal stroma, and corneal endothelium follow, each section comprehensively covering applied anatomy, current therapy and regenerative techniques, with a look to future directions of the field including eventual cell therapy. Corneal Regeneration: Therapy and Surgery is the first book of its kind, systematically covering the developments the medical community has achieved in corneal regeneration from all angles. Written and edited by leading experts in the field, researchers and ophthalmologists alike will find this to be a unique source of information on corneal regeneration, as well as a thoughtful reflection on potential applications of regenerative surgery in ophthalmology as a whole.

Book Description
Continuous regeneration of the cornea is necessary to maintain this tissue in the transparent state that is essential for vision. Therapy for repair of the damaged anterior cornea is currently addressed through the transplantation of donor corneas or the delivery of limbal epithelial stem cells (LESC) to the ocular surface using amniotic membrane (AM) as a supporting scaffold. Research on the bioengineering of corneal equivalents as replacement tissue is underway to develop viable corneal prosthetics. Corneal Regenerative Medicine: Methods and Protocols provides a concise overview of essential techniques in the field of corneal regenerative medicine, highlighting novel strategies to guide the management of key therapies within this area of medicine. Divided into four convenient sections, topics include the identification, characterisation and cultivation of LESC, as well as the investigation of biopolymers used as the basis for corneal substitutes. Written in the successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Corneal Regenerative Medicine: Methods and Protocols covers the fundamental techniques useful for both the laboratory and clinical settings.

Book Description
The notion of being able to engineer complete organs has inspired an entire generation of researchers. While recent years have brought significant progress in regenerative medicine and tissue engineering, the immense challenges encountered when trying to engineer an entire organ have to be acknowledged. Despite a good understanding of cell phenotypes, cellular niches and cell-to-biomaterial interactions, the formation of tissues composed of multiple cells remains highly challenging. Only a step-by-step approach will allow the future production of a living tissue construct ready for implantation and to augment organ function. In this book, expert authors present the current state of this approach. It offers a concise overview and serves as a great starting point for anyone interested in the application of tissue engineering or regenerative medicine for organ engineering. Each chapter contains a short overview including physiological and pathological changes as well as the current clinical need. The potential cell sources and suitable biomaterials for each organ type are discussed and possibilities to produce organ-like structures are illustrated. The ultimate goal is for the generated small tissues to unfold their full potential in vivo and to serve as a native tissue equivalent. By integrating and evolving, these implants will form functional tissue in-vivo. This book discusses the desired outcome by focusing on well-defined functional readouts. Each chapter addresses the status of clinical translations and closes with the discussion of current bottlenecks and an outlook for the coming years. A successful regenerative medicine approach could solve organ shortage by providing biological substitutes for clinical use - clearly, this merits a collaborative effort.
