Table 1. Qualitative relative expression of Sox factors in developing pancreas and adult islets of the mouse.

Legend: Data indicate the qualitative representation of relative abundance of Sox family member expression in whole embryonic mouse E12.5 and E15.5 pancreata and isolated adult islets, as surveyed by RT-PCR [66, 67]. Symbols: -: not detected; +, ++, +++: detected in increasing abundance, respectively. Absence of a symbol indicates expression not examined [66, 67]. *+: Sox9 transcripts initially detected in isolated adult islets [66], but (-) not in a subsequent study [16].
