Study Notes
Growth of Cell Biology
- Cell biology research experienced rapid growth in the 1950s, paralleling advancements in molecular biology.
- The capability to maintain, grow, and manipulate cells outside living organisms was established.
HeLa Cells
- First continuous cell line cultured in 1951 by George Otto Gey and his team, derived from Henrietta Lacks' cervical cancer cells.
- HeLa cells became a pivotal tool in the study of cell biology, similar to the significance of DNA structure in molecular biology.
Advancements in Cell Study
- The 1960s yielded significant progress, which included:
- Characterization of minimal media requirements for cell cultures.
- Development of sterile cell culture techniques.
- Electron microscopy advancements facilitated enhanced cellular study, leading to discoveries like:
- Transfection methods for introducing nucleic acids into cells.
- Green fluorescent protein (GFP) from jellyfish, aiding in visualization of cellular processes.
- Discovery of small interfering RNA (siRNA), crucial for gene regulation studies.
Continued Evolution of Cytology
- The study of cell structure and function is known as cytology.
- Continuous advancements in equipment, such as cytology microscopes and specialized reagents, support research, particularly in clinical applications.
