1. Air force centrifuge

3. Centrifuge
A machine that spins materials and separates materials of different densities.

5. Using a centrifuge to separate out the parts of a cell

6. Ultracentrifuge

8. Light Microscope
Uses light to produce a larger view of an object. Curved lenses bend the light to enlarge the image.

33. Resolution –
the ability of a microscope to show two points that are close together as separate images

34. Red Blood Cells

37. Microdissection

38. Microdissection
Dissect cells under a microscope. E.g. remove the nucleus of a cell

40. Intracytoplasmic Sperm Injection

41. Tissue Culture
A way to keep living cells alive while outside the body. Copy a normal environment in a petri dish.

43. HeLa cells stained with antibody to actin (green) , vimentin (red) and DNA (blue)

44. HeLa cells
Henrietta Lacks

45. The cells were propagated by George Otto Gey shortly before Lacks died of her cancer in This was the first human cell line to prove successful in vitro, which was a scientific achievement with profound future benefit to medical research. Gey freely donated both the cells and the tools and processes his lab developed to any scientist requesting them, simply for the benefit of science. Neither Lacks nor her family gave Lacks's physician permission to harvest the cells, but, at that time, permission was neither required nor customarily sought. The cells were later commercialized, although never patented in their original form. Then, as now, there was no requirement to inform a patient, or their relatives, about such matters because discarded material, or material obtained during surgery, diagnosis, or therapy, was the property of the physician and/or medical institution (this currently requires ethical approval and patient consent in the UK). This issue and Lacks's situation was brought up in the Supreme Court of California case of Moore v. Regents of the University of California. The court ruled that a person's discarded tissue and cells are not their property and can be commercialized.
