Transcriptome of postnatal mouse heart

The present study aimed at determining the differences in global mRNA expression between proliferating cardiomyocytes in the 2-day-old heart and growth arrested cardiomyocytes in 13-day-old heart of ICR mice. The transcriptomic profiles of the samples at the two time points(day 2 and day 13 of postnatal stage) were analyzed by direct comparison of the transcriptional level between the two groups of heart on the same custom 12×135K microarray (Roche NimbleGen)
