Table 2 The life span and the hTERT mRNA levels of three different HFLC isolates, clonal derivatives and cBAL111

From: Novel immortalized human fetal liver cell line, cBAL111, has the potential to differentiate into functional hepatocytes

Cell source Maximal PDs hTERT mRNA copies/18S rRNA copies
HFLCs, 16 weeks 57.6 ± 10.2 Undetectable (n = 4)
cBAL08 61 2.7 *104 (n = 1)
cBAL09 30 Not determined
cBAL20 38 Undetectable (n = 1)
cBAL21 31 Undetectable (n = 1)
cBAL29 42 2.4 *105 ± 1.9 *105 (n = 3)
cBAL111 Immortal 2.6 *109 ± 3.2 *108 (n = 4)
  1. Life span is indicated as the maximum number of population doublings (PDs).
