Question

While smooth muscle tissue can regenerate from stem cells called pericytes, dead cardiac muscle tissue is replaced by what type of tissue?

Answer 1

scar tissue

10.9 Development and Regeneration of Muscle Tissue Muscle tissue arises from embryonic mesoderm. Somites give rise to myoblasts and fuse to form a myotube. The nucleus of each contributing myoblast remains intact in the mature skeletal muscle cell, resulting in a mature, multinucleate cell. Satellite cells help to repair skeletal muscle cells. Smooth muscle tissue can regenerate from stem cells called pericytes, whereas dead cardiac muscle tissue is replaced by scar tissue. Aging causes muscle mass to decrease and be replaced by noncontractile connective tissue and adipose tissue.
