Table 5. The distribution of promoter usage in the SC types and the negative controls (NCs); the upper right section of the table considers the CpG-rich SPs and the lower left section considers the CpG-poor SPs.

P-values calculated using the Welch two sample t-tests. The promoters are characterized using the Baek et al (2007) scheme. The key to the abbreviations: ESC - embryonic SC; ASC - adult SC; qASC - quiescent adult SC; pASC - proliferating adult SC; NC - negative control. The first and the last rows and columns provide the SC type and the mean±the standard deviation are given in parenthesis.
