More than cell dust: microparticles isolated from cerebrospinal fluid of brain injured patients are messengers carrying mRNAs, miRNAs, and proteins.
Silke Patz,Christa Trattnig,Gerda Grünbacher,Birgit Ebner,Christian Gülly,Alexandra Novak,Beate Rinner,Gerd Leitinger,Markus Absenger,Oana Alina Tomescu,Gerhard G. Thallinger,Ulrike Fasching,Sonja Maria Wissa,Juan-Jose Archelos-Garcia,Ute Schäfer +14 more
TL;DR: The transfer of genetic material from CSF microparticles to adult neuronal stem cells in vitro and a subsequent microRNA-specific repression of distinct genes are confirmed, marking the first indication of a regulated transport of functional genetic material in human CSF.

TL;DR: Analysis of endogenous and ectopically expressed or silenced miR-451a in Ntera2/D1 cells during neuronal differentiation and compared neuronal differentiation in the dentate gyrus of hippocampus of miR -451a-/- and wild type mice provide strong support for a role in neuronal maturation processes in vitro and in vivo.

TL;DR: Cell elongation on walls and a critical surface energy level for cell adhesion could be produced for NT2/D1 and MC3T3-E1 cells by symmetrical and asymmetrical energy barrier levels are evaluated by evaluation of cell behaviour on synthetic microstructures exhibiting pronounced differences in surface energy.

TL;DR: Results indicate that the polymeric niche has a distinct impact on various cell characteristics and the selection of distinct polymers and the controlled design of an optimized polymer microenvironment might thereby be an effective tool to promote essential cell characteristics for subsequent approaches.
