Defining trophoblast injury patterns in the transcriptomes of dysfunctional placentas.

Trophoblast injury is central to clinically relevant placenta dysfunction. We hypothesized that the mRNA of primary human trophoblasts, exposed to distinct injuries in vitro , capture transcriptome patterns of placental biopsies obtained from common obstetrical syndromes. We deployed a CIBERSORTx deconvolution method to correlate trophoblastic RNAseq-based expression matrices with the transcriptome of omics-defined placental dysfunction patterns in vivo. We found distinct trophoblast injury patterns in placental biopsies from women with fetal growth restriction and a hypertensive disorder, or in biopsies clustered by their omics analysis. Our RNAseq data are useful for defining the contribution of trophoblast injuries to placental dysfunction syndromes. • We compared RNAseq matrices in cultured trophoblasts and in placental samples. • CIBERSORTx deconvolution method correlated in vitro and in vivo injury patterns. • Correlations were strongest in preeclampsia and fetal growth restriction clusters.
