1.4 - Cellular differentiation Flashcards
cellular differentiation is the process by which…
a cell expresses certain genes to produce proteins characteristic for that type of cell
what does cellular differentiation allow a cell to do
carry out specialised functions
where do plants differentiate into specialised cells from
meristems
where do animals differentiate into specialised cells from
embryonic and tissue stem cells
what are meristems and what can they do
regions of unspecialised cells in plants that can self renew and/or differentiate
what is a stem cell and what can it do
unspecialised cells in animals tat can self renew and/or differentiate
what stage of embryo is used for stem cells
very early embryo
t/f embryonic stem cells can differentiate into all cell types
t
are embryonic stem cells multi or pluripotent
pluripotent
t/f all genes in an embryonic stem cell can be switched on
t
what are tissue stem cells involved in
growth, repair and renewal of the cells found in that tissue
are tissue stem cells multi or pluripotent
multipotent
what can a multipotent stem cell do
differentiate into all cell types found in a particular tissue type
give examples of therapeutic stem cells
corneal repair, regeneration of damaged skin
what is the general therapeutic use for stem cells
the repair of damaged or diseased organs or tissues
