Multiple Choice
In developmental and stem cell biology, a stem/progenitor cell that gives rise to muscle (myogenic lineage) is most commonly referred to as a what?
A
Chondroblast
B
Myoblast
C
Osteoblast
D
Fibroblast
Verified step by step guidance1
Understand that the question is asking for the specific name of a stem or progenitor cell that differentiates into muscle cells, which is part of the myogenic lineage.
Recall that in developmental biology, different progenitor cells are named based on the tissue type they give rise to: for example, chondroblasts form cartilage, osteoblasts form bone, and fibroblasts form connective tissue.
Identify that the progenitor cell responsible for muscle formation is called a myoblast, which is a precursor cell that will differentiate into muscle fibers.
Recognize that the term 'myoblast' directly relates to muscle ('myo-' prefix) and is the correct term for a muscle progenitor cell.
Conclude that among the options given, 'Myoblast' is the correct answer because it specifically refers to the stem/progenitor cell that gives rise to muscle tissue.
