Large Differences in Small RNA Composition Between Human Biofluids. [PDF]

open access: yes, 2018
Extracellular microRNAs (miRNAs) and other small RNAs are implicated in cellular communication and may be useful as disease biomarkers. We systematically compared small RNAs in 12 human biofluid types using RNA sequencing (RNA-seq).

Developmental potential of mouse embryos without extraembryonic membranes in modified organ culture.

open access: yesCollegium antropologicum, 2004
The long-term stationary culture of postimplanatation embryos without extraembryonic membranes is a method to assess their developmental potential in vitro. The method was almost exclusively used on rat embryos, while mouse embryos were considered unsuitable due to their poor differentiation.
