1. A method for increasing the proliferative capacity of normal cells having telomerase activity, which method comprises culturing or cultivating said cells in the presence of an oligonucleotide substrate for telomerase under conditions such that said oligonucleotide substrate enters said cells and acts to lengthen telomeric DNA of said cells and the proliferative capacity of said cells is increased.

3. A method of making human hybridoma cells with increased proliferative capacity, said method comprising:
-
(a) culturing an immortal cell line in the presence of an oligonucleotide substrate for telomerase under conditions such that the telomeres in cells of said cell line lengthen, anti the proliferative capacity of said cells is increased; and (b) fusing said cells cultured in step (a) with human antibody-producing cells to produce said hybridoma cells.
