Stem Cells Flashcards
What are stem cells also known as?
Blank cells or undifferentiated cells
Define “Stem Cells”
Blank cells that can differentiate into a range of different cell types, depending on its potency
What is the order of potency?
Totipotent, pluripotent, multipotent, ogliopotent, unipotent
How many types of cells can totipotent cells differentiate into?
