Ultimate Stem Cells

Once upon a time, we were these four cells. They came from two cells, and those two cells came from the fertilization of an egg cell by a sperm cell. Every cell, every type of tissue, and every organ in your body originated from these four little cells. The instructions to make you are literally within yourself. This is why these types of cells are called stem cells. They are the stem from which all other cells grow from. Buy this piece for yourself or give it as a gift. It makes an excellent present for stem cell researchers, fertility specialists, cell biologists, and starry-eyed pre-med students.
