lecture 6 - stem cells Flashcards
(29 cards)
what are embryonic stem cells responsible for
producing different cell types
what are adult stem cells responsible for
maintaining different cell types
what are the two paths stem cells can take
cell division decision
differentiation decision
what happens after the cell division decision
self renewal
unlimited division
what happens after the differentiation decision
limited division
differentiation
how are stem cells characterised
what is the origin
the physical place the stem cells come from
what are the five types of embryonic stem cells
hematopoietic
mesenchymal
neural
epithelial
cardiac
what is the foetal stem cell type
embryonic
what is the disease stem cell type
cancer stem cell
what is the lab made stem cell type
induced pluripotent stem cell

whole organisms
what is the totipotent stem cell type
zygote
what do pluripotent stem cells differentiate to
all types of cells
what is the pluripotent stem cell type
embryonic stem cell
what do multipotent stem cells differentiate to
most types of cells S
What is the multipotent stem cell type
adult stem cells
what is the oligopotent stem cell type
corneal
what do the oligopotent differentiate to
few type of cells
what do the unipotent stem cells differentiate to
one type of cell
what is the unipotent stem cell type
germ stem cell
what are embryonic stem cells grown from
cells found in embryo when it is just a dew days old at a stage known as blastocyst
what forms the placenta
the outer cell layer
what are the growing conditions of embryonic stem cells
addition of purified growth hormones and growth factors
