2
Cell Growth - Differentiation & Specialization
Stem Cells
3
How does your body grow bigger?
Heal an injury?
4
Cells reproduce! The process by which a cell splits into two new daughter cells is called cell division.
5
How many cells did we start out as?
Zygote Blastocyst Embryo Fetus Human Development - Zygote to Infant
6
Cell Differentiation is the process in which a cell develops into a specific type of cell within a multicellular organism. Ex) Muscle, skin, leaf, root cell
7
The original cell or stem cell changes in response to triggers from the body or itself into different cells.
8
WHAT ARE STEM CELLS? Stem Cells are undifferentiated (unspecialized) cells that can… Create other kinds of cells that specialize through differentiation Create more stem cells Stem Cell Story TED Ed - Stem Cells
9
Research on stem cells Medical researchers believe that stem cell therapy has the potential to dramatically change the treatment of human disease. A number of adult stem cell therapies already exist, particularly bone marrow transplants that are used to treat leukemia.
10
Research on stem cells
11
Potential uses of stem cells
NOVA - Replacing Body Parts Made to Order - Stem Cell Organs CBS 60 Minutes - Growing Body Parts
13
Potential problems One concern of treatment is the risk that transplanted stem cells could form tumors and become cancerous if cell division continues uncontrollably. Medical vs. Ethical Debate (embryonic cells)
