Genetic Engineering Part I (Stem Cells)

From Article
fertilized egg
process of dividing body cells
developmental stage consisting of a solid ball of cells
developmental stage consisting of a hollow ball of cells
ICM (Inner Cell Mass)
group of stem cells found in the blastula that will later become the embryo
developmental stage marked by folding layers of cells to become differentiated body tissues
developmental stage when a distinct form of an organism appears
stem Cells
undefined or undifferentiated cells that can become any type of cell of the body
pluripotent stem cells
cells capable of becoming any type of body cell
multipotent stem cells
cells capable of becoming only a few types of body cells
location of multipotent stem cells
bone marrow, hair follicles, umbilical cord blood, and dental pulp
location of pluripotent cells
somatic nuclear transfer
creating a new embryo by joining an enucleated egg and an adult body cell (cloning)
creating a replica of an original
Induced Pluripotent Stem Cells
How IPSCS are made
using transforming factors to reprogram an adult body cell's nucleus back into its embryonic state
cells become specialized cells of the body by having certain genes turned on while turning other's off
cells are already specialized
Why are stem cells NOT obtained from the gastrula stage?
an egg which has had its nucleus removed
biggest road block to developing cures with stem cells
transforming factors
chemicals used to reprogram body cells to make IPSCS
mitosis and differentiation
two processes that allow for zygote the develop into an embryo
zygote, morula, blastula, gastrula, then embryo
What are the stages of embryonic development in order? (same stages seen in all animals)
