[Completed] The pancreatic islet B cells, called islet 13 cells in the article, awakened and "fell in love" with their master (not love, more of a forced attachment, which can be regarded as family affection). And his owner has type 2 diabetes. The author is a biology scumbag. If there are any laxities in the article, you are welcome to criticize and correct me!
