Cell biology is constantly evolving, with a groundbreaking discovery by Charles Xu and his research team. They discovered a new organelle called PXo organelle, which regulates phosphate transport in fruit fly guts. Xu and his team observed that even with minimal phosphate, the gut cells grew rapidly. They also discovered that the PXo bodies, which have a spiral arrangement of cell membranes, help transport phosphate from the cytoplasm into the bodies, regulating the supply of phosphate for cellular functions. This discovery has significant implications for understanding development, behavior, and disease mechanisms in fruit fly models
