Contrary to the view that the developmental process is intrinsically determined and precisely regulated, cell competition is widely existing. By cell competition, less fit cells are eliminated while more fit cells get the chance to expand their clones. Although the molecular basis to distinguish such difference has been identified such as Myc heterogeneity and apico-basal cell polarity, the molecular mechanism and precise process remain to be poorly understood. More importantly, cell competition is very common during tissue regeneration and tumorigenesis, emphasizing the importance to investigate such process. Also, such cell competition is also related to other essential cellular process such as quality control systems. Here, I choose two research paper about this topic. One is about dissecting the signaling involved in the competition and how it is related to immune response, and another is the work to look close to see how winner cells expand them to compensate for the space the loser cells leaves.
