Abstract
This study was carried out to analyze the telomeres distribution and telomerase activity of several chicken cells. The target cells were sperms ovulated ova early embryonic cells and the cells from brain heart liver kidney lymphocytes and germinal tissue in Korean Native Chicken. Telomeres distribution on target cells was analyzed by Q-FISH techniques using a chicken telomere repeat probe. Telomerase activity was performed by TRAP assay with target DNA. In results the telomeres of chicken were found at the ends of all chromosomes. In addition chicken had interstitial telomeres on chromosomes 1 2 and 3. Telomerase activity was highly detectable in early embryonic cells germinal tissues and kidney cells. Whereas telomerase activity was gradually down-regulated in the organs including brain heart and liver. In the distribution of telomeric DNA on the cells of embryonic developmental and growing chick stages the amount of telomeres gradually decreased as growth in most of the cells.
