    • Compositions comprising porcine retinal cells and methods for using the compositions to treat retinal disorders are described. The porcine retinal cells are preferably fetal neural retina cells or retinal pigment epithelial cells. The porcine retinal cells can be modified to be suitable for transplantation into a xenogeneic subject, such as a human. For example, the porcine retinal cells can be modified such that an antigen (e.g., an MHC class I antigen) on the cell surface which is capable of stimulating an immune response against the cell in a xenogeneic subject is altered (e.g., by contact with an anti-MHC class I antibody, or a fragment or derivative thereof) to inhibit rejection of the cell when introduced into the subject. In one embodiment, the porcine retinal cells are obtained from a pig predetermined to be free from organisms which originate in pig and which are capable of transmitting infection or disease to the recipient subject. The porcine retinal cells of the present invention can be used to treat a xenogeneic subject having a retinal disorder (e.g., a human with retinis pigmentosa, light damaged retina and macular degeneration) by introducing the cells into the retina of the subject.
    • 描述了包含猪视网膜细胞的组合物和使用该组合物治疗视网膜疾病的方法。 猪视网膜细胞优选胎儿神经视网膜细胞或视网膜色素上皮细胞。 猪视网膜细胞可以被修饰以适合于移植到异种对象如人中。 例如,可以修饰猪视网膜细胞,使得细胞表面上能够刺激针对异种受试者中的细胞的免疫应答的抗原(例如,MHC I类抗原)被改变(例如通过与 抗-MHC I类抗体或其片段或衍生物)以在引入受试者时抑制细胞排斥。 在一个实施方案中,猪视网膜细胞从预先确定为不含源自猪的生物体并且能够将感染或疾病传递至受体个体的猪获得。 通过将细胞引入受试者的视网膜,本发明的猪视网膜细胞可以用于治疗具有视网膜疾病的异种受试者(例如,具有视网膜色素变性的人,光损伤的视网膜和黄斑变性)。
