30603914-0	2019	The proliferative lifespan of adult sheep fibroblasts can be conditionally extended by tetracycline-inducible expression of human telomerase reverse transcriptase.	Tetracycline	87-99	telomerase reverse transcriptase	Homo sapiens	130-162	
30603914-2	2019	Here, we report conditional extension of proliferative lifespan of adult sheep somatic cells by introducing tetracycline-inducible (Tet-on) expression of hTERT.	Tetracycline	108-120	telomerase reverse transcriptase	Homo sapiens	154-159	
30603914-3	2019	After transfecting adult sheep fibroblasts with the vector for Tet-on induced conditional expression of hTERT, we obtained several hTERT-positive clones that exhibited extended-lifespan under the induction of tetracycline analogue, doxycycline.	Tetracycline	209-221	telomerase reverse transcriptase	Homo sapiens	131-136
