STEM CELLS
SCNT - SOMATIC CELL NUCLEAR TRANSFER
!! GENETIC MATCH !!
EGG CELL
NUCLEUS REMOVED
SOMATIC CELL INSERTED
ARTIFICIAL ACTIVATION
EMBRYO IS CREATED
SOMATIC CELL "FORGETS ITS IDENTITY AND BECOMES TOTIPOTENT"
ES (EMBRIONIC STEM) CELLS
PLURIPOTENT
DERIVED FROM EMBRYOS
IN VITRO FERTILIZATION
DIVISION
BLASTOCYST - RESULT OF N DIVISIONS
TROPHOBLAST - BECOMES PLACENTA
INNER CELL MASS - BECOMES EMBRYO
INNER CELLS CAN BE CULTURED AND CONDITIONED TO SPECIALIZE IN SOME TISSUES
!! NO GENETIC MATCH !!
TYPES
TOTIPOTENT
PLURIPOTENT
MULTIPOTENT
UNSPECIALIZED CELLS
CAN RENEW TROUGH CELL DIVISION
BECOME DIFFERENT CELLS DEPENDING ON THE SIGNALS THEY GET
