From: Dysregulated hematopoiesis in bone marrow marks severe COVID-19

a UMAP plot of B cells from BMMCs and PBMCs. b, c Proportion of B cells among total cells and three types of B cells among total B cells, with results from PBMC samples (b) and BMMC samples (c). d Somatic hypermutation rate of IGHV, IGKV, and IGLV from three groups and two origins. e Total SARS-CoV-2-specific antibody titers and SARS-CoV-2-specific IgG titers of six patients at different time points after symptom onset. The BM puncture was done between the 18th and 31st day after symptom onset.
