Fig 1. MiRNAs measured at different lactation periods in whole human preterm milk.

Candidate endogenous references (let-7a, let-7g, let-7d, miR-16, miR-21 and miR-146b) were measured in mature human milk collected within month 2 of lactation, from 28 to 65 days postpartum. The Cq values of each miRNA are shown by box-and-whisker plots (1–99 percentile).
