The immortalized human BMEC cell line, hCMEC/D3, in vitro blood-brain barrier model is useful in long-term functional studies.
hCMEC/D3 media components EBM-2 and hydrocortisone are cytotoxic to peripheral blood mononuclear cells (PBMCs).
Co-culture media excluding EBM-2 and hydrocortisone support hCMEC/D3 barrier function as well as continued PBMC viability.
Co-culture media can be used in assays of PBMC transmigration.
