Unit 1: Stem Cells & Differentiation

Question	Answer
Why Do Organisms Have Tissue Stem Cells?	To Replenish differentiated cells that need to be replaced
What Are Two Therapeutic Uses Of Stem Cells?	•Corneal Transplant •Growing skin grafts for burns
Give An Example Of A Tissue Adult Stem Cell	Cells in bone marrow which go on to differentiate into all the cells of the blood
What Is A Stem Cell?	UnSpecialised cells in animals which are capable of making copies of themselves or differentiating to form specialised cells
What Does Multi-potent Mean?	Can differentiate into a limited range of cells
What Are Some Of The Ways That Stem Cells Can Be Used In Research?	Used as model cells to test drugs, used to study cell processes like growth and differentiation and gene regulation
What Does Pluri-potent Mean?	Can differentiate into all the cell types needed by the organism
What Is The Difference Between Tissue Stem Cells & Embryonic Stem Cells?	Tissue stem cells can only differentiate into a narrow range of cells by embryonic stem cells can become all cells needed by the organism
Why Do People Have Ethical Concerns With The Use Of Embryonic Stem Cells?	Embryos get destroyed which some people think is the same as murder
What Is Meant By Differentiation?	Process by which a cell develops more specialised functions by expressing the genes characteristic for that type of cell
