Maternal Immune System and State of Inflammation Dictate the Fate and Severity of Disease in Preeclampsia

Figure 2

Immune cell analysis in placental tissue specimens from PPE vs. preterm controls with/out smoking history. mRNA levels of the human Foxp3, CD4, CD8, CD56, CD68, CD45, transcripts were analyzed in placental tissue by real-time polymerase chain reaction (RT-PCR) in PPE vs. preterm controls with/out smoking history. 1 μg total RNA was reverse transcribed in 20 μl reaction. A total of 2 μl cDNA and the 1 μM real-time PCR primers purchased from Real Time Primers, LLC (Elkins Park, PA) were used for amplification in Bio-Rad CFX-96 Real Time System. Expression of the target genes was normalized to β-actin and displayed as fold change relative to the preterm control sample. Data are representative of specimens isolated from 8-30 specimen samples belonging to subjected used in the study. s denotes smoker, and ns denotes nonsmoker. represents statistically different with value <0.05.
