[Abstract]  Cellular barcoding enables the dissection of clonal dynamics in heterogeneous cell populations through single cell lineage tracing. The labeling of hematopoietic stem and progenitor cells (HSPCs) with unique and heritable DNA barcodes, makes it possible to resolve donor cell heterogeneity in terms of differentiation potential and lineage bias at the single cell level, through subsequent transplantation and high-throughput sequencing. Furthermore, cellular barcoding allows for bona fide hematopoietic stem cells (HSCs) to be defined based on functional rather than immunophenotypic parameters.

This protocol describes the work flow of lentiviral cellular barcoding, tracking 14.5 days post coitum (d.p.c.) fetal liver (FL) Lineage-Sca+cKit+ (LSK) HSPCs following ...
[摘要]  细胞条形码可以通过单细胞谱系追踪来分离异种细胞群体中的克隆动力学。通过独特和可遗传的DNA条形码对造血干细胞和祖细胞(HSPC)进行标记,可以通过随后的移植和高通量测序,在单细胞水平上分化供体细胞异质性,分化潜力和谱系偏倚。此外,细胞条形码可以根据功能而不是免疫表型参数定义真正的造血干细胞(HSC)。
 该协议描述了慢病毒细胞条形码的工作流程,追踪1450天后(dpc)胎肝(FL)Lineage-Sca+ cKit + (LSK)HSPC经过长期重建(图1)(Kristiansen等人,2016),但可以适应于选择的细胞类型或时间框架。

最初建立了细胞条形码技术来解决在体内移植造血细胞后的单细胞动力学,并且近年来在移植中对血细胞群体中功能​​异质性的认识有显着贡献(Schepers ,2008; Gerrits等人,2010; Lu等人,2011; Naik等人 ,2013; Verovskaya等人,2013; ...
