Stem Cells And The Human Body

1170 Words5 Pages
Stem cells are different to all other cells in the human body because they have unique abilities to divide repeatedly, make many copies of themselves or differentiate into specialised cells such as skin cells, immune cells or nerve cells. Stem cells are also described as unspecialised because they are not yet advanced to perform an exact function. However, each of them has the potential to develop into one of a number of different specialised cell types depending on the body’s needs at a particular time. Specialized cells are different in size, shape and function. Some of the cells such as white blood cell allows the body to fight off the infection, while the nerve cells carry the impulses. Each cells have a significant function and failure of one can cause the others to work inefficiently because these group of specialized cells form tissues such as muscle, skin, nerve cells. Then, group of tissues form organs such as heart, lungs, stomach. Organs come together to form system like respiratory system, digestive system and then the entire system forms a human body. As they are all in one way connected to each other, malfunction or failure in a group of cells makes the body worse and sick. (Multiple Sclerosis Trust, 2016) To begin with, all of many different kinds of stem cells can be Totipotent, Pluripotent, Multipotent or Unipotent. Totipotent can make all cell types such as Zygotes and early embryo cells while pluripotent are able to produce all cells originated from a
