          <dc:description>&lt;p dir="ltr"&gt;This dataset accompanies the study “Atlas of the immune cell development in the human fetal blood”. It includes processed single-cell RNA sequencing data, T-cell and B-cell receptor annotations, flow cytometry data, Olink normalized protein expression (NPX) measurements, single-cell pseudobulk expression data, bulk transcriptomic data from PHA-stimulated peripheral blood mononuclear cells (PBMCs), and sample metadata. Analysis code and supporting documentation are available in the linked GitHub repository.&lt;/p&gt;&lt;p dir="ltr"&gt;&lt;b&gt;Data files&lt;/b&gt;&lt;/p&gt;&lt;ul&gt;&lt;li&gt;&lt;b&gt;Fetal_Immune_Atlas.h5ad&lt;/b&gt; — Integrated single-cell atlas containing 235,494 cells from blood, liver, thymus and spleen, with gene expression data and cell metadata.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Fetal_Immune_Atlas_TCR.h5ad&lt;/b&gt; — TCR-associated single-cell data and annotations.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Fetal_Immune_Atlas_BCR.h5ad&lt;/b&gt; — BCR-associated single-cell data and annotations.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Fetal_Immune_Atlas_Sample_Metadata.csv&lt;/b&gt; — Sample metadata and assay availability for 37 samples from 25 donors.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Fetal_Immune_Atlas_Olink_NPX.xlsx&lt;/b&gt; — Olink NPX measurements.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Fetal_Immune_Atlas_scRNA_Pseudobulk_TPM.csv&lt;/b&gt; — Gene-level expression aggregated from single-cell RNA sequencing for 21 PBMC samples, with 20,719 genes and expression values reported as TPM.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Fetal_Immune_Atlas_PHA_Bulk_TPM.csv&lt;/b&gt; — Bulk RNA sequencing expression values in TPM for 16 PHA-stimulated PBMC samples, with 39,453 gene entries.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Fetal_Immune_Atlas_Flow_Blood_FCS_01.zip&lt;/b&gt; and &lt;b&gt;Fetal_Immune_Atlas_Flow_Blood_FCS_02.zip&lt;/b&gt; — Blood flow cytometry FCS files, distributed across two archives.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Fetal_Immune_Atlas_Flow_Organs_FCS_01.zip&lt;/b&gt;, &lt;b&gt;Fetal_Immune_Atlas_Flow_Organs_FCS_02.zip&lt;/b&gt;, and &lt;b&gt;Fetal_Immune_Atlas_Flow_Organs_FCS_03.zip&lt;/b&gt; — Organ flow cytometry FCS files, distributed across three archives.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Fetal_Immune_Atlas_Flow_Blood_23Color.wsp&lt;/b&gt; — FlowJo workspace for the 23-color blood flow cytometry analysis.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Fetal_Immune_Atlas_Flow_Organs_24Color.wsp&lt;/b&gt; — FlowJo workspace for the 24-color organ flow cytometry analysis.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Fetal_Immune_Atlas_Flow_Sample_Metadata.xlsx&lt;/b&gt; — Sample information for the spectral flow cytometry experiments.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Fetal_Immune_Atlas_Flow_Proportions.xlsx&lt;/b&gt; — Cell proportions measured by flow cytometry.&lt;/li&gt;&lt;/ul&gt;&lt;p dir="ltr"&gt;&lt;b&gt;Using the data&lt;/b&gt;&lt;/p&gt;&lt;p dir="ltr"&gt;The H5AD files can be opened with AnnData or Scanpy. Tabular data are provided in CSV or Excel format. Each flow cytometry ZIP archive can be extracted independently; extract all five archives into the same directory to preserve the FCS folder structure. The WSP files contain the corresponding FlowJo workspaces. When opening a workspace, locate the extracted FCS files if prompted. Sample identifiers and assay availability are documented in the sample metadata tables.&lt;/p&gt;&lt;p dir="ltr"&gt;&lt;b&gt;Analysis code&lt;/b&gt;&lt;/p&gt;&lt;p dir="ltr"&gt;Analysis scripts, preprocessing workflows, figure-specific documentation and data placement instructions are available at &lt;a href="https://github.com/thekingofall/scFetallife_Blood" target="_blank"&gt;https://github.com/thekingofall/scFetallife_Blood&lt;/a&gt;.&lt;/p&gt;&lt;p dir="ltr"&gt;&lt;b&gt;Author contributions&lt;/b&gt;&lt;/p&gt;&lt;p dir="ltr"&gt;Xiufang Wang, Lipeng Mao and Ruiling Yan contributed equally to the associated study.&lt;/p&gt;</dc:description>
