Embryonic stem cells are stem cells derived from the inner cell mass of an early stage embryo
B. What is the difference between a blastocyst and a fetus?
The blastocyst is an early stage of mammal development early in pregnancy..A fetus is a developing mammal after the embryonic stage and before birth
C. Do you know of other sources for stem cells? Elaborate
Embryonic (explained above), adult stem cells which are found in adult tissues, and cord blood stem cells which are found in the umbilical cord.
D. What are advantages to using adult stem cells?
Advantages= Ability to self-renew indefinitely and generate all the cell types of the organ that they come from,potentially regenerating the entire organ from a few cells.
E. What are the advantages to using adult stem cells? What are the disadvantages to using embryonic stem cells?
Thus far only adult and cord blood stem cells have been successful in treating disease.
I. What are the disadvantages to using adult stem cells?
They are multipotent progenitor cells, meaning while they can create a large number of things.. they are still limited.
G What are their possible uses in medicine?
Cancer, Parkinson's disease, spinal cord injuries, and muscle damage and other conditions
