Stem cells Flashcards
A stem cell
is an undifferentiated cell of an organism which is
capable of giving rise to many more cells of the same type, and
from which certain other cells can arise from differentiation
What can stem cells from humans make
Stem cells from adult bone marrow can form many types of cells
including blood cells.
Meristem tissue in plants can
n differentiate into any type of plant cell,
throughout the life of the plant.
Stem cells from human embryos can be cloned and made to
differentiate into most different types of human cells to treat what diseases?
Treatment with stem cells may be able to help conditions such as
diabetes and paralysis.
What is therapeutic cloning
In therapeutic cloning an embryo is produced with the same genes
as the patient. Stem cells from the embryo are not rejected by the
patient’s body so they may be used for medical treatment.
What are the risks of using stem cells as treatment
The use of stem cells has potential risks such as transfer of viral
infection, and some people have ethical or religious objections.
Mutations have been observed in stem cells cultured for a number of generations, and some mutated stem cells have been observed to behave like cancer cells.
The difficulty in obtaining and storing a patient’s embryonic stem cells.
bone marrow operation hurts
Stem cells from meristems in plants can be used to produce clones
of plants quickly and economically to do what
Rare species can be cloned to protect from extinction.
*
Crop plants with special features such as disease resistance
can be cloned to produce large numbers of identical plants for
farmers.
