A team in Japan found something new in cells. Cells can change their shape. This happens without help from outside. The team found tiny parts. They call them SpTAs. These are special proteins inside cells. They move on their own.
Scientists Discover How Cells Can Change Shape on Their Own
Easy
Actin is a natural protein in all living cells. SpTAs are different from normal actin. They can move by themselves. The movement is called treadmilling. New parts add to one end. Old parts leave from the other end. This makes the protein walk forward.
SpTAs move in many directions. Together, they push the cell wall. The wall bulges out. These bulges make the cell shape. This is how cells organize themselves. The team learned a big secret about life.
