We proposed to detect the transcriptome/mirnaome of inner cell mass of porcine.The bottleneck for this study is that we could get very few cells ( about 10 from each blastocyst,~10 blastocyst for each fertilized porcine.We prepared 5 pigs for this experiment. So, we could get ~ 500 cells. ) Is so many cells enough for transcriptome/mirnaome analysis by Illumina Hiseq 2000? What else is worthy of note?

Here are a couple links to resources for amplifying small amounts of RNA. I have used the first two, and they work well.
Nugen Ovation RNA-Seq:
Modified Illumina RNA-Seq protocol (look in the supplemental data):
Linear amplification of RNA:

DSN protocol really works. We used non detectable amount of total RNA as an input for library prep and got ~30M passing reads from single GAIIx lane. Unique read was ~5M, so higher redundancy as you expected from extremely low input material, but this was great!

NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification,...-
