Cell Specialization, Bone marrow/Hair follicle, Zygote first 4 cells,…
Cell Specialization
Stem cell
Pluripotent cell
Specialization
Morphogens (chemical signallers)
Goes from head downwards
Concentration drops as it goes
Diff receptor loading
Diff concentrations trigger cells to specialize into specific organs
Fruit Fly case study
It's easy to study
Cell division is synchronous
Cell division fast
Bone marrow/Hair follicle
Multipotent cell
Differentiation
Phloem cells
Cardiac cells
Muscle cell
Retinal cells
Zygote first 4 cells
Totipotent cell
Specialization
Embryo cells
Lots of variety who the cell can become
No variety
Zygote
Morula
Blastocyst
Inner cell mass
Embryo
Trophoblast
Placenta
