Cell differentiation

Eukaryotic

animal cells

Cytoplasm

fluid containing a system of membranous organelles, nonmembranous molecular assemblies and a cytoskeleton

blastomeres

produced in the first zygotic cellular division = early embryo inner cell mass

give rise to all tissue types of the fetus

embryonic stem cells

cells of the inner cell mass explanted to tissue culture

differentiation

predominantly express sets of genes that mediate specific cytoplasmic activiies becoming efficiently organized in tissues with specalized functions and changing shape accordingly
