Question

Compare and contrast diploid cell culture and continuous cell culture.

Accepted Answer

Step 1: Define diploid cell culture and continuous cell culture. Diploid cell cultures are derived from normal cells that have a finite lifespan and maintain a diploid chromosome number, meaning they have two sets of chromosomes. Continuous cell cultures, on the other hand, are derived from transformed or cancerous cells that can proliferate indefinitely and often have an abnormal chromosome number (aneuploidy). Step 2: Compare the lifespan and growth characteristics. Diploid cell cultures have a limited number of cell divisions before senescence (they stop dividing), while continuous cell cultures can divide indefinitely due to their transformed nature. Step 3: Discuss the applications and uses. Diploid cell cultures are often used for vaccine production and studies requiring normal cell physiology, whereas continuous cell cultures are used for research requiring large quantities of cells, such as cancer research or production of recombinant proteins. Step 4: Contrast the genetic stability. Diploid cell cultures maintain genetic stability and normal chromosome number, while continuous cell cultures often show genetic instability and chromosomal abnormalities. Step 5: Summarize the differences in morphology and behavior. Diploid cells tend to grow in a monolayer and exhibit contact inhibition (stop growing when they touch each other), whereas continuous cells may grow in multiple layers and often lose contact inhibition, leading to uncontrolled growth.
