(A–B) Scatter plots of C19MC (A) and non-C19MC (B) miRNA
profiles, comparing miRNA in each of the EVs and the Ago-2 bound fraction to the
miRNA landscape of PHT cells. The heatmap depicts the correlation matrix of
miRNA profiles, including three trophoblastic EVs, extracellular Ago2
population, and parental PHT cells. The regression lines for AP, Exo, and MV
were generated by ordinary least square linear regression and by locally weighed
scatterplot smoothing (LOWESS) for Ago2. (C) Heatmap of the top 20 miRNAs,
ascending by the mean Ct values of PHT cells, ABs, MVs, EXs, and extracellular
Ago2 population. Trophoblastic EVs and Ago2 population were isolated from three
independent PHT cells. Statistical significance was analyzed as described in
Methods.
