Study discovers Foxo3 protein helps eliminate 'unfit' cells to ensure healthy body construction
From the very moment an egg is fertilized, life begins with a remarkable process: cells start dividing and replicating to make copies of themselves. Yet this process is not flawless. Errors can occur when genetic material is copied, creating "unfit" cells that don't work properly. To keep development on track, cells employ a fascinating quality control system called cell competition. However, much about this mechanism remains unclear.
