Numerous to abundanceof chondrocytes expressed FGFR1 in articularcartilage, but only few osteocytes of spongy bonecontained these receptors (Figs 5 and 6, Table 2). Totalapoptosis affected mainly chondrocytes, althoughonly few moderated osteocytes died in this way(Fig. 7, Table 2). Both matrix metalloproteinasesdegraded the cartilage (Fig. 8, Table 2). However,variable number of osteocytes also expressed thesecollagenases in each case (Table 2).LLU Raksti 18 (313), 2007; 51-5753
