The aim of this field is to preserve, repair, or replace ocular cells that have been injured or lost. We now better understand the complexity of how the eye develops, the cellular and regional heterogeneity that builds complex ocular tissues, and how these processes are disordered in disease. Ocular diseases affect the entire age spectrum, and loss of vision significantly affects the quality of life for those with blinding eye conditions. With our aging population, the burden of ocular disease is expected to rise over the next decades. As we enter the age of regenerative medicine, the eye has become the proving ground for first-in-man stem cell clinical trials. This is in part because of its accessibility for minimally invasive surgical approaches to deliver cellular therapeutics, the availability of multimodal behavioural, physiological, and imaging techniques, and the sheer number of patients that new treatments could potentially impact. The purpose of the book is to provide those interested in the field of ocular regenerative medicine with a perspective on the various ways in which stem cells are being applied in the development of potential cures for blinding eye diseases. The aim is to provide a review-level understanding of the types, sources, and applications of stem cells in regenerating tissues in various parts of the eye, with a perspective on the promise of stem cell applications, as well as challenges confronting the field. It is intended for those with a background in the biological and/or medical sciences. The field will depend increasingly on multidisciplinary collaboration between scientists, physicians, and engineers as we develop the tools needed to realize the full potential of stem cells to heal the eye. The scope of the text is broad and includes both preclinical and clinical applications, including stem cell-derived therapies based on endogenous tissue repair, stem cell transplantation/cell replacement therapy, the interface with gene therapy, and in vitro disease modelling. Applications in both anterior and posterior ocular disease are described, with a particular focus on diseases of the ocular surface/cornea/limbus, where stem cell transplantation has already found clinical application in patients, as well as diseases of the retina, where early clinical trials have begun for both RPE v vi Preface and photoreceptor replacement. Targets of these therapies include inherited retinal dystrophies as well as acquired diseases, such as age-related macular degeneration. As editors, we have had the pleasure of working with these researchers to bring this volume together. We extend our gratitude and thanks to all of the authors for their time and commitment to this volume and for providing their perspectives on this rapidly expanding field.

In most cases, loss of visual function results from the death of photoreceptors, the specialized cells involved in photo- transduction. An innovative and efficient therapeutic solution for retinal degenera- tive diseases may be photoreceptor cell transplantation. Yet, the human eye contains about one hundred million photoreceptors, and cell replacement therapy would require at least a fraction of this, raising the issue of where to find an abundant source of healthy human photoreceptors to treat patients. Human pluripotent stem cells can be expanded quasi-indefinitely and differentiate into all cell types of the human body. Methods to direct the differentiation of human pluripotent stem cells into retinal cells and photoreceptors have been developed based on developmental biology principles. Here, we review the history and evolution of these methods, looking at two-dimensional and three-dimensional cell culture systems. We also analyze the current outcomes of photoreceptor cell transplantation therapy and explore the upcoming challenges for its clinical translation.
