2. The difference between tissue engineering and stem cell engineering is the source of
the cells in question. Tissue engineering depends upon a sample of cells from the
diseased organ of the host; for many patients, however, a tissue biopsy may not yield
normal cells for expansion and transplantation. Human embryonic stem cells are
envisioned as a viable source of cells from which the desired tissue can be derived. Stem
cell engineering will provide an endless source of versatile cells.
9. The roles of normal stem cell are a) to transform itself into a cell of any kind of tissue
needed by the body; b) to divide regularly and essentially without limit to replenish worn
out or damaged tissues in some organs; c) to act as delivery vehicles in medical
experimentation, such as in testing potential anti-tumor medications.
PROBLEMS ANSWERS:
1. An example of the smallest component in a physiological system is: the smallest
