Human platelet lysate is a successful alternative serum supplement for propagation of monocyte-derived dendritic cellsŠvajger, UrbanBackground aims. Clinical protocols for dendritic cell (DC) generation from monocytes require the use of animal serum- free supplements. Serum-free media can also require up to 1% of serum ... supplementation. In addition, recommendations based on the 3Rs (Refinement, Reduction, Replacement) principle also recommend the use of non-animal sera in in vitro studies. The aim of this study was to explore the potential use of platelet lysate (PL) for generation of optimally differen- tiated DCs from monocytes. Methods. Cells were isolated from buffy coats from healthy volunteers using immunomagnetic selection. DCs were differentiated in RPMI1640 supplemented with either 10% fetal bovine serum (FBS), 10% AB serum or 10% PL with the addition of granulocyte monocyte colony stimulating factor and interleukin-4. Generated DCs were assessed for their morphology, viability, endocytotic capacity, surface phenotype (immature, mature and tolerogenic DCs) and activation of important signaling pathways. DC function was evaluated on the basis of their allostimulatory capacity, cytokine profile and ability to induce different T-helper subsets. Results. DCs generated with PL displayed normal viability, morphology and endocytotic capacity. Their differentiation and maturation phenotype was comparable to FBS-cultured DCs. They showed functional plasticity and up-regulated tolerogenic markers in response to their environment. PL-cultured mature DCs displayed unhindered allostimulatory potential and the capacity to induce Th1 responses. The use of PL allowed for activation of crucial signaling proteins associated with DC differentiation and maturation. Discussion. This study demon- strates for the first time that human PL represents a successful alternative to FBS in differentiation of DCs from monocytes. DCs display the major phenotypic and functional characteristics compared with existing culture protocols.Vir: Cytotherapy. - ISSN 1465-3249 (Vol. 19, iss. 4, Apr. 2017, str. 486-499)Vrsta gradiva - članek, sestavni delLeto - 2017Jezik - angleškiCOBISS.SI-ID - 33118169
