Objective:
Identify overlap of the transcriptome of myometrium and cervix in association with human labor.
Study Design:
The transcriptional profile of myometrial and cervical biopsies obtained from women in spontaneous labor at term (n = 9) and not in labor (n = 9) were characterized by Affymetrix v2 U133 plus 2 arrays. Common canonical pathways and functional groups were identified by Ingenuity Pathway Analysis.
Results:
One hundred ten genes (false discovery rate < 1%) were commonly up-regulated by myometrium and cervix in association with labor and 29 genes (false discovery rate < 1%) down-regulated. Fold change in expression of up-regulated genes was strongly correlated; myometrium vs cervix (r = 0.51; P < .001), with no relationship in down-regulated genes (r = 0.26; P = .16). Canonical pathway analysis established up-regulation of inflammatory pathway signaling, with greatest increases in cellular movement and immune response gene ontology groups.
Conclusion:
Gestational tissues exhibit a core inflammatory response in association with human parturition, with pathways regulating cellular trafficking dominating.

Embryonic Connective Tissues
The mesenchyme is the first connective tissue that emerges in the developing embryo. It consists of loosely arranged multipotent mesenchymal cells and reticular fibers in the extracellular matrix. This loose arrangement allows easy migration of cells, which is essential for germ layer positioning, patterning, and organ morphogenesis during embryonic development. Mesenchyme is...

Menses Phase
When fertilization does not occur, the corpus luteum deteriorates, causing a significant drop in the levels of estrogen and progesterone in the body. This hormonal decrease triggers the release of prostaglandins, which cause the uterine...
