Question

Answer in terms of True (T) or False (F) and explain why:

a. T/F: Pax7+Myf5- cells represent a cell population of expanding myoblasts during regeneration.

b. T/F: Pax3 deletion during embryogenesis results in lethality due to defects in muscle and neural development.

c. T/F: One major limitation precluding the use of satellite cells for regenerative purposes is low frequency and the current incapacity to expand these cells in the Petri dish (in vitro) without differentiation.

d. T/F: Manual testing remains today as the gold standard method used to assess strength.

Explanation / Answer

a . True

They are satellite cells represented during regeneration.

b . True

This is a mutant which shows defects.

c . True

satellite cells are used for regeneration

d . True

Microscopic examination remains as manual gold standard method.
