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
