Background and Aim: The peripheral blood mononuclear cell (PBMC) is an excellent cell source for in vitro studies, particularly those involving immunology. The aim of this study was to determine the quality and quantity of chicken PBMCs isolated from freshly drawn blood as well as blood that had been chilled for 24 h. In addition, the survival of PBMCs cultured in medium was investigated.

Materials and Methods: Blood samples were collected from 12 Betong and 12 Leghorn chickens. Hemograms were analyzed. Density gradient centrifugation was used to isolate PBMCs. PBMCs (2×106 cells/mL) were cultured in a culture medium and incubated in a CO2 incubator for 5 consecutive days. The number of viable cells was determined using the trypan blue dye exclusion method.

Results: Blood samples were obtained from healthy chickens. There was no statistically significant difference in the total amount of PBMC between fresh and refrigerated blood samples from both chicken breeds. The viability of PBMCs isolated from fresh blood (95%) was significantly greater than blood refrigerated for 24 h (90-92%) in both breeds. Furthermore, the viability of PBMCs isolated from both blood samples decreased significantly over time, from 90-95% to 60-65%.

Conclusion: The total number of PBMC in fresh and refrigerated blood was not significantly different. Fresh blood-derived PBMCs had significantly higher viability than 24 h refrigerated blood PBMCs. Furthermore, the viability of PBMCs decreased significantly over time. Keywords: Betong chicken, cell viability, leghorn chicken, lifespan, peripheral blood mononuclear cell.
