Marker Expression of Interstitial Cells in Human Skeletal Muscle: An Immunohistochemical Study.

Summary of "Marker Expression of Interstitial Cells in Human Skeletal Muscle: An Immunohistochemical Study."

There is a growing recognition that myogenic stem cells are influenced by their microenvironment during regeneration. Several interstitial cell types have been described as supportive for myoblasts. In this role, both the pericyte as a possible progenitor for mesenchymal stem cells, and interstitial cells in the endomysium have been discussed. We have applied immunohistochemistry on normal and pathological human skeletal muscle using markers for pericytes, or progenitor cells and found a cell type co-expressing CD10, CD34, CD271, and platelet-derived growth factor receptor α omnipresent in the endomysium. The marker profile of these cells changed dynamically in response to muscle damage and atrophy, and they proliferated in response to damage. The cytology and expression profile of the CD10+ cells indicated a capacity to participate in myogenesis. Both morphology and indicated function of these cells matched properties of several previously described interstitial cell types. Our study suggests a limited number of cell types that could embrace many of these described cell types. Our study indicate that the CD10+, CD34+, CD271+, and platelet-derived growth factor receptor α+ cells could have a supportive role in human muscle regeneration, and thus the mechanisms by which they exert their influence could be implemented in stem cell therapy.

Medical and Biotech [MESH] Definitions

Mature contractile cells, commonly known as myocytes, that form one of three kinds of muscle. The three types of muscle cells are skeletal (MUSCLE FIBERS, SKELETAL), cardiac (MYOCYTES, CARDIAC), and smooth (MYOCYTES, SMOOTH MUSCLE). They are derived from embryonic (precursor) muscle cells called MYOBLASTS.

Large, multinucleate single cells, either cylindrical or prismatic in shape, that form the basic unit of SKELETAL MUSCLE. They consist of MYOFIBRILS enclosed within and attached to the SARCOLEMMA. They are derived from the fusion of skeletal myoblasts (MYOBLASTS, SKELETAL) into a syncytium, followed by differentiation.

An anoctamin chloride channel expressed at high levels in the liver, skeletal muscle, and gastrointestinal muscles that functions in transepithelial anion transport and smooth muscle contraction. It is essential for the function of the INTERSTITIAL CELLS OF CAJAL and plays a major role in chloride conduction by airway epithelial cells and in tracheal cartilage development.

Elongated, spindle-shaped, quiescent myoblasts lying in close contact with adult skeletal muscle. They are thought to play a role in muscle repair and regeneration.

c-Kit positive cells related to smooth muscle cells that are intercalated between the autonomic nerves and the effector smooth muscle cells of the gastrointestinal tract. Different phenotypic classes play roles as pacemakers, mediators of neural inputs, and mechanosensors.
