RNA-Seq for primary rat Kupffer cells and monocytes treated with hepatic stellate cell-derived small extracellular vesicles

Aim: To find out the effects of small extracellular vesicles (sEVs) from short-term activated and long-term activated hepatic stellate cells (HSCs) on Kupffer cells (KCs) and bone marrow-derived monocytes (MOs). Methods: To isolate HSC-derived sEVs, culture media (CMs) from Day 0 to Day 3 and Day 7 to Day 14 were collected. The sEVs from Day 0 to Day 3 HSC CMs were referred to as short-term activated HSC-sEVs (3dHSC-sEVs), and those from Day 7 to Day 14 HSC CMs were referred to as long-term activated HSC-sEVs (14dHSC-sEVs). Purified primary rat KCs and MOs were cocultured with 3dHSC- or 14dHSC-sEVs for 48 h. HSC-sEVs cocultured KCs or MOs were lysed in TRIzol (Life Technologies) for RNA sample preparation at the indicated time points. Untreated primary rat KCs and MOs served as control.
