Despite an occasional penetration of an embryo cell into the mother and vice versa, there is a placental barrier between the two tissues.
Considerable differences in fatty acid composition were observed between the two tissues.
The scientists hypothesize that the parallel evolution of bigger brains and weaker muscles on the human lineage may not have been a coincidence, but rather due to a "reallocation" of energy resources between the two tissues.
The junction between the two tissues produces a cavity that provides some temporary protection to the basidia, although they are already fertile when the cap margin starts to grow.
In nine of the interactions, the miRNA was differentially expressed between the two tissues.
Different sized immunoreactive peptides were detected between the two tissues, indicating potential tissue-specific processing of MSTN.
The classification of repetitive elements was broadly similar between the two tissues, mainly comprising LINE, SINE and LTR repeats.
The mutational spectra did not deviate significantly between the two tissues and mainly consisted of GC to AT transition mutations (Figure 4).
There was no significant difference in the average expression levels of these 176 genes between the two tissues (p = 0.79, paired t-test).
In order to functionally characterize transcripts that are differentially expressed between the two tissues, we searched for enrichment of Gene Ontology (GO) 'biological process' annotations (see Methods).
Nine of the 33 miRNA families with significant enrichment or depletion in at least one set were differentially expressed between the two tissues in our miRNA microarray data.
