What is the difference in cell cultures and cell fractionation?
culturing is growing cells in a laboratory, usually in little petri dishes. Fractionation is breaking apart cells from some natural source
What is the science behind animal testing?
Stage 1: Human Cells - Early tests are done on human cells grown in a laboratory. Scientists try out different concentrations of a possible new drug. They test it on different types of body cells with the disease. These tests check how well the chemical works against the disease. They also give data about how safe the drug is for cells. Stage 2: Animal Tests - If the drug passes tests on human cells, it is tried on animals. Animal trials are carried out to make sure the drug works as well in whole animals as it does on cells grown in the laboratory. Stage 3: Clinical Tests - If the drug passes the animal trials, then it can be tested on people, these tests are called clinical trials or human trials. They give scientists more data about the effectiveness and safety of the drug
What does adoptive immunotherapy entail?
stimulating T lymphocytes by exposing them to tumor antigens. These modified cells are grown in the laboratory and then injected into patients
A scientist wants to grow human cells to use an experiment. What should the scientist do to grow and maintain cells in the laboratory?
The scientist should prepare a culture of the cells. (apex)
Is the amount of DNA in a human body cell the same as the amount of DNA in a human egg cell?
No. The amount of DNA in human sperm cells is half of the amount found in body cells.
Which cells might be used in laboratory to make heart cells?
Liver cells

because the body makes it that way
How do you grow crank?

Which cells might be used in a laboratory to make a heart cell?
Liver cells

Are there any human tissues that may be relatively more easily obtained for study?
Newer studies do suggest that adult stem cells may have cells that are not easily grown after isolation from mature adult tissues.
How many cells does a full grown cell have?
cells don't contain other cells
