My passion is cell theory because, for a career, I want to be a doctor. A recent advancement into biology called the stem cell could be revolutionary to medical science. Cell theory is a scientific theory that proposes that all living organisms are made of cells. Stem cells are a particular cell that the body produces.

Stem cells are cells that can transform into other cells and carry out their functions. They are used to treat blood and immune disorders. Biologists are excited about discovering two variants of these particular cells: Embryonic stem cells (ESCs) and Pluripotent stem cells (iPSCs). These variants are more versatile and can adapt to the new environment in the human body. Stem cells can cure many diseases like diabetes, cancer, heart disease, Alzheimer’s, Parkinson’s, etc. However, they have not been used in practical therapy. Stem cell treatment has been tried on a human. In Japan, a 6-year-old boy with urea cycle disorder, a condition that lets ammonia build up in the bloodstream, was the first person to receive the world’s first stem cell transplant successfully. Stem cell therapies have the main goal to overcome: the human body has a finite amount of cells. At some time in a person’s life, they will no longer repair or replace cells. Diseases like cancer can kill cells quicker than the body can produce cells with can lead to death.
