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.hese stem cells come from embryos that are three to five days old. At this stage, an embryo is called a blastocyst and has about 150 cells. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body.

Prior to the Industrial Revolution, which began in Britain in the late 1700s, manufacturing was often done in peopleâs homes, using hand tools or basic machines. Industrialization marked a shift to powered, special-purpose machinery, factories and mass production.
