The present invention generally relates to methods and compositions to determine viability of an organ for transplantation and other medical purposes. One aspect of the invention relates to a method for assessing the viability of an organ by measuring the energy parameters to determine the energy level of the organ by determining the stored cellular energy (e.g., ATP levels), and/or energy consumption over a particular time period of viability. The energy parameters can be compared to reference energy parameters as a highly accurate and reliable prediction of viable cell yield, and organ viability. Another aspect of the invention relates methods to preserve or extend the time period of viability of an organ any combination of (i) preservation perfusion of the organ to prevent ischemic damage, (ii) chemical metabolic suppression of the organ e.g., using metabolic suppressants, (iii) metabolic suppression by physical or environmental conditions, e.g., sub-zero non-freezing storage.
本发明一般涉及确定用于移植和其他医疗目的的器官存活能力的方法和组合物。本发明的一个方面涉及一种评估器官存活能力的方法,该方法通过测量能量参数来确定器官的能量
水平,具体方法是确定储存的细胞能量(如
ATP 水平)和/或存活特定时间段内的能量消耗。能量参数可与参考能量参数进行比较,从而高度准确可靠地预测存活细胞产量和器官存活率。本发明的另一个方面涉及保存或延长器官存活时间的方法,这些方法可以是以下方法的任意组合:(i) 对器官进行保存灌注以防止缺血性损伤;(ii) 对器官进行
化学代谢抑制,例如使用代谢
抑制剂;(iii) 通过物理或环境条件进行代谢抑制,例如零度以下的非冷冻储存。
