What are some of the ethical issues that arise from using embryonic stem cells?(b) To avoid these issues, scientists use IPSCs. What are the pros and cons to using iPSCs inrelation to embryonic stem cells?
You have been asked to do a strucutural study to understand how increasing cell surface area affects cell size, cell shape and functions. What cell type would help you most efficiently observe the effects of increasing surface area?
Choices:
A. Monocytes from the blood serum. Monocytes are largely roughly spherical cells.
B. Red Blood cells from the bone marrow. The shape of Red blood cells is a biconcave disk and looks like a donut.
C. Stem cells from skin. In this case assume a skin stem cell is flat and plate like.
D. Microvilli covered cells from the intestines. Microvilli are tiny hair like protrusions in the plasma membrane of intestinal cells that increase the absorption of nutrients in the intestines.
