title: The enrichment of trophoblast giant cells from mid-gestation bovine placentae using fluorescence-activated cell sorting.
abstract: The objective of this work was to determine if fluorescence-activated cell sorting (FACS) can be used to isolate trophoblast giant cells (TGCs) from bovine placentae. Cotyledons were harvested, minced and digested with dispase/pancreatin. Tissue homogenates were incubated with Vybrant Dye Cycle-Green. FACS was completed, and cells with DNA content 2- to 4-times greater than cells within the diploid peak contained between 65 and 84% TGCs. The relative abundance of CSH1 and PAG1 transcripts were greater (P < 0.05) in TGC-enriched fractions than cells within the diploid peak. These observations indicate that FACS can effectively enrich TGCs from bovine placentae.
