Chapter 9.6, Problem 2TC
Summary Introduction
To determine: The reason why researchers were concerned by the given discovery.
Introduction: A stem cell is a cell that has the potential to develop into specialized cell types in a body. The stem cells are present throughout the life of an individual. They are the foundation of each tissue in our body.

As a cancer researcher, which segment of the signal transduction pathway would you target to prevent the spread of cancer and why?
New treatments for several conditions are being developed using stem cells in medical waste, such as biopsy material, teeth, menstrual blood, umbilical cords, and fatty tissue removed in liposuction. For example, fat samples from injured horses are used to grow stem cells to treat tendon injuries. Explain how the two defining characteristics of stem cells enable them to be used to replace damaged or diseased tissue, so that the new tissue functions as opposed to forming a scar.
What is this? What special ability does it have? Does it have organelles to perform this activity?
