Myo/Nog cells, named for their expression of MyoD and noggin, enter the eye during early stages of embryonic development. Their release of noggin is critical for normal morphogenesis of the lens and retina. Myo/Nog cells are also present in adult eyes. Single nucleated skeletal muscle cells designated as myofibroblasts arise from Myo/Nog cells in cultures of lens tissue. In this report we document the presence of Myo/Nog cells in the lens, ciliary body and on the zonule of Zinn in mice, rabbits and humans. Myo/Nog cells were rare in all three structures...

The population of patients on left ventricular assist devices (LVADs) has increased significantly since the 1990s, and with it, need for non-cardiac elective surgeries. Presence of an LVAD or heart failure, however, can cause physicians to perceive these patients to be at prohibitively high risk for elective surgery. Nevertheless, as one of the most common causes of poor vision in the elderly, cataracts can significantly limit improvements in quality of life that a patient may have otherwise gained from LVAD support...

BACKGROUND: Visual function and brain function decline concurrently with aging. Notably, cataract patients often present with accelerated age-related decreases in brain function, but the underlying mechanisms are still unclear. Optical structures of the anterior segment of the eyes, such as the lens and cornea, can be readily reconstructed to improve refraction and vision quality. However, the effects of visual restoration on human brain function and structure remain largely unexplored...
