What are stem cells?
|
Self renewing cells that are also capable of differentiating into more specialized cells.
|
|
|
|
Cell differentiation is when cells go from an immature form to that which has biological function.
|
These cells are different because they express a subset of their 30,000+ genes.
|
|
|
|
What is a pluripotent cell?
|
Embryonic stem cells obtained from the inner cell mass of a blastocyst
|
the inner cell mass becomes the embryo
|
|
|
What is a multipotential cell?
|
Cells that can produce a limited range of differentiated cell lineages appropriate to their location.
|
Hematopoietic stem cells from bone marrow exemplify multipotential cells
|
|
|
What is a unipotential cell?
|
Cells capable of producing only 1 cell type
|
epidermal stem cells, adult liver stem cells
|
|
|
Whats an embryonic stem cell?
|
Undifferentiated cells with the ability to form any adult cell. They can proliferate indefinitely in culture & provide an unlimited source of adult cells.
|
|
|
|
How can stem cells be beneficial?
|
*Provide functional immune system to individuals with SCID
*Replace defective hematopoietic system in patients with nonmalignant genetic disorder (sickle cell) |
*Replace hematopoietic system of cancer patients after chemotherapy
|
|
|
Possible stem cell risks?
|
Cells from any source other than yourself or a twin can lead to rejection.
