“I was able to spar the other day. I felt good. My leg feels healthy,” said Cormier. “In like the third, fourth week is when the stem cells really start to take shape, really start to help the healing process. I’m in week five now. Man, I feel pretty good. I don’t have much pain in it. I just really have to control myself as I go forward because you want to go in head first.” Stem cells have been tested on for many years. Stem cells are cells that are unspecialized cells and they divide into specialized cells. The there are many types of stem cells, the three main types are: Embryonic stem cells, non-embryonic stem cells or adult stem cells, and induced pluripotent stem cells (iPSCs). Through years of research scientists

According to NIH scientists are just beginning to understand the signals inside and outside cells that trigger each step of the differentiation process. The internal signals are controlled by the gene’s of the cell, while the external signals that cause differentiation include chemicals that are secreted by the neighboring cells, physical contact with neighboring cells, and certain molecules in the nearby environment or in this case the nearby microenvironment. Scientists are currently still doing research about stem cells. Currently they are trying to answer two questions. Those questions are: Why can embryonic stem cells proliferate for a year or more in the laboratory without differentiating, but most adult stem cells cannot; and what are the factors in living organisms that normally regulate stem cell proliferation and self-renewal? Even though they’ve been studying for years they still don’t know everything about stem cells. This shows how complicated it stem cells are. Answering the questions from earlier would be a great scientific breakthrough, hopefully someday these questions do get answered. Another question that they should try to answer could be can you manipulate the cells to differentiate to specific cells. Eventually scientists will learn more about what causes stem cells to differentiate. Someday they might even be capable of manipulating the cells to differentiate into specific organs and
