电子植入系统可监测胰岛细胞发育过程为构建功能成熟的人源胰岛提供关键技术平台

Core Viewpoint - Researchers have developed an electronic implant system that can monitor and influence the maturation process of human islet cells, providing a key technological platform for constructing functionally mature human islets and offering new insights for cell-based diabetes therapies [3][4]. Group 1: Technology Development - The electronic implant system integrates a thin conductive mesh structure into growing pancreatic tissue, allowing for the recording of electrical signals produced by islet cells and the application of precise electrical stimulation to influence their development [3][5]. - This system is described as "bionic" or "cyber-organ," combining electronic systems with living tissues to create a controllable biological system [3]. Group 2: Application in Diabetes Treatment - In Type 1 diabetes, the immune system attacks islet cells, leading to a loss of insulin secretion capability. Laboratory-cultured functional pancreatic tissue is seen as a potential alternative to donor pancreas or islet transplants, which are limited by donor availability and require long-term immunosuppressive therapy [4]. - The research team implanted a stretchable electronic mesh within developing three-dimensional pancreatic organoids, enabling the recording of electrical activity from individual islet cells for up to two months and observing their maturation process [5]. Group 3: Findings and Future Applications - The introduction of a 24-hour electrical activity cycle similar to the human biological clock resulted in islet cells maintaining this rhythmic activity and hormone secretion at appropriate times after several days of rhythmic stimulation [5]. - This technology may have two potential applications: training laboratory-cultured islet cells through electrical stimulation before transplantation, or retaining the electronic mesh post-transplantation for continuous monitoring and stimulation to prevent functional decline under stress or disease [5].
