Stem cells are the body's raw materials â cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells. These daughter cells either become new stem cells (self-renewal) or become specialized cells (differentiation) with a more specific function, such as blood cells, brain cells, heart muscle or bone. No other cell in the body has the natural ability to generate new cell types.
How to Tie a Hangmans Noose. Community Q&A. The Hangman's noose is perhaps the best-known knot in the world, and is ubiquitous on TV, in movies, and children's games. The Hangman is also used as a knot to tie angles to fishing-line.
