Cells of the Human Body
How do stem cells become specialized cells?
Certain genes are turned on and off to allow them to become specialized
adult(somatic) stem cells
adult cells in the body
pluripotent
can divide into almost every type of cell
totipotent
can divide into any cell
multipotent
can divide into several types of cells
embryonic stem cells
derived from embryos
What are the three types of stem cells?
embryonic, somatic, iPSC
ethics
moral principles(what is okay and what is not okay)
How many kinds of cells are in the body
more than 200 different kinds
do all cells have the same size and shape
no, their size, shape, and structures are specialized for a specific function
iPSCs (induced pluripotent stem cells)
stem cells that are differentiated/specialized that scientists turn back into embryonic stem cells
What does undifferentiated mean?
the cells are not specialized yet
bioethnics
the ethics involved with science and medical research
What happens after stem cells differentiate?
they become specialized cells in the human body
what are stem cells?
undifferentiated cells that can differentiate into any type of cell depending on what instructions they're given
How are stem cells described
using potency
