However, to date, most of these novel technologies have not been broadly applied to non-model organisms such as teleost fish. In this study, we used the 10× Genomics single cell RNA sequencing technology and used it to analyze for the first time in teleost fish the transcriptional pattern of single B cells from peripheral blood. The analysis of the data obtained in rainbow trout revealed ten distinct cell clusters that seem to be associated with different subsets and/or maturation/differentiation stages of circulating B cells. The potential characteristics and functions of these different B cell subpopulations are discussed on the basis of their transcriptomic profile. The results obtained provide us with valuable information to understand the biology of teleost B cells and offer us a repertoire of potential markers that could be used in the future to differentiate trout B cell subsetsengAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/journal article2079-7737https://doi.org/10.3390/biology10060511open access577.21TeleostB cellsSingle cell transcriptomicsImmunoglobulinsImmune markersTranscription factorsLong non-coding RNAsBioquímica (Biología)Química orgánica (Química)Peces31 Ciencias Agrarias2306 Química Orgánica2403 Bioquímica
