Chapter 13 Flashcards
totipotent
describes a cell with the ability to differentiate into any cell type in the body
cellular differenetiation
the process by which a cell specializes to carry out a specific role
tissues
an organized group of different cell types that work together to carry out a particular function
induced pluripotent stem cells
pluripotent stem cell that was generated by manipulated of a differentiated somatic cell
pluripotent
describes a cell with the ability to differentiate into nearly any cell type in the body
differential gene expression
the process by which genes are “turned on” or expressed, in different cell types
adult stem cells
stem cells located in tissues that help maintain and regenerate those tissues
multipotent
cells with restricted ability to differentiate
SCNT
somatic cell nuclear transfer
cloning
the nucleus of a haploid unfertilized human egg is replaced with the diploid nucleus taken from another cell
produces a new embryo with the same genes as the donor cell
stem cells
relatively unspecialized cells that can divide and differentiate into different cell types
therapeutic drugs
stimulate stem cells to grow and differentiate into specialized cell types
regenerative medicine
seeks to prod stem cells to divide, prod stem cells to differentiate, and stimulate stem cells to make cell types they wouldn’t normally make
cloning
somatic cell nuclear transfer (SCNT)
the nucleus of a human egg cell is replaced with diploid nucleus of somatic cell which forms an embryo that can be cultured
cell therapy
remove stem cells, chemically induce to divide, and then re-implant cells
de-differentiation
cells can do this with the adding of genes or proteins
