Abstract:
Morphometric analysis of the ultrastructural changes of satellite cells (SCs) of rat soleus muscle 7, 14, and 36 days post denervation was performed. Denervation caused decrease of surface area cross-section of SCs and their nuclei, volume fractions of nucleus and Golgi complex elements and ribosomes number. In contrast, the increase of surface area/volume ratio of SCs and nucleus, volume fraction and number of endosome/lysosome-like structures, and number of caveolae-like structures was noticed. Ultrastructural changes of SCs in denervated muscles strongly suggest decline of cell activity accompanied by increased processes of degradation of material of endo-, and/or egzogenous origin.
