TRANSCRIPT
The cell is the basic unit of
life
Cell Membrane
Nucleus
Nucleolus
Mitochondrion
Golgi
Rough ER
Smooth ER
Lysosome
Vacuole
The Nucleus contains the cell’s genetic material (genome)
Genetic material in the form of DNA Molecules are organized into structures called chromosomes
HeLa cells stained withHoechst dye for DNA
White cellRed Cells
Neural Cells
Skin Fibroblast
Kidney Cells
Fat Cells
Liver Hepatocytes
Liver Stellate Cell
There are more than 200 different types of cells in your
body

Cells are Organized into TissuesMultiple Tissues form Organs
•Tissue culture is the growth of tissues and/or cells under artificial conditions
•Henrietta Lacks’ cells were named He La cells
•HeLa cells were the 1st to be kept alive outside of the body
What do scientists do with cells?
HeLa Cells – The Launchpad for Advances in Biomedical Research
Vaccines (Polio, HPV, Etc)
Virology (HIV, HPV-18)
Recombinant Protein Production (Insulin)
Insulin Receptor
