Telocytes accompanying cardiomyocyte in primary culture: two- and three-dimensional culture environment.

Zhou J, Zhang Y, Wen X, Cao J, Li D, Lin Q, Wang H, Liu Z, Duan C, Wu K, Wang C - J. Cell. Mol. Med. (2010)

Bottom Line: Noteworthy, telocytes seem to play a significant role in the normal function and regeneration of myocardium.The results showed that typical telocytes are distributed among cardiomyocytes, connecting them by long telopodes.Also, a significant number of vimentin+ telocytes were present within engineered heart tissue.

Immunohistochemical staining for vimentin in engineered heart at day 14. (A) Vimentin+ cells in engineered heart tissues. (B) Vimentin+ telocyte with long and extremely thin prolongation (telopodes) and vimentin, discontinuously expressed along the prolongation (arrow). Bar = 50 μm (A), 20 μm (B).

(B) Vimentin+ telocyte with long and extremely thin prolongation (telopodes) and vimentin, discontinuously expressed along the prolongation (arrow). Bar = 50 μm (A), 20 μm (B).

Mentions: We used immunohistochemical staining for antigens expressed in telocytes: c-kit, CD34 and vimentin. c-kit or CD34+ telocytes existed in engineered heart tissue with long cell processes (Figs 7 and 8). In addition, a number of vimentin+ cells were observed in engineered heart tissues (Fig. 9A). Among these cells, telocytes appeared with long and extremely thin telopodes. Vimentin is discontinuously expressed along these telopodes (Fig. 9B), presumably due to the tortuous telopodes’ three-dimensional path.
