Venous blood was drawn into an ethylenediaminetetraacetic acid (EDTA) S-monovette (Sarstedt, Nümbrecht, Germany) for immunophenotyping. Whole blood (100 µl per flow cytometry panel) was directly stained in FACS tubes with fluorescence-labeled antibodies (BD-Biosciences, Franklin Lakes, United States: CD8-PerCP-Cy5.5, CD5-PE, CD45RA-PE-CF594, CD19-PE-Cy5, CD4-PE-Cy7, CD45RO-APC, CD38-A700, CD3-APC-H7, CD138-BV421, CD10-BV510, CD27-BV605, CD14-PE-CF594, CD19-PE-Cy5, CD25-PE-Cy7, CD16-A700, CD3-APC-H7, CD11b-BV421, HLADR-BV510; Biolegend, San Diego, United States: CD11c-BV605; Miltenyi Biotec, Bergisch-Gladbach, Germany: BDCA1-APC, BDCA2-PE) for 15 min in the dark at room temperature (RT). After washing, red blood cell (RBC) lysis was performed with 2 ml ACK lysing buffer (Thermo Scientific, Waltham, United States) for 7 min in the dark at RT. 2 ml of FACS buffer (phosphate buffered saline, 3% fetal calf serum, 1% sodium azide) was added to wash the samples twice. Subsequently, cells were resuspended in 400 µl FACS-buffer. After the staining procedure, cells were measured by flow cytometry (LSR Fortessa cytometer, BD Biosciences, Franklin Lakes, United States) and analyzed with FACS-Diva Software (BD Biosciences, Franklin Lakes, United States). The gating strategy is available in the supplementary data section of this paper (Supplementary Figure S7).

Unstimulated and TLR-Stimulated CD34+ hematopoietic progenitors were plated at 10,000 cells/well for liquid, stromal cell-free B lineage cultures, or 1000 cells per sample in Methocult H4434 Classic (Stemcell Technologies), according to the manufacturer’s directions, as previously described [4 (link),5 (link),18 (link),19 (link)]. For B lineage liquid culture, cells were grown in QBSF®60 (Quality Biological, Inc.) supplemented with 10% FBS (Atlanta Biologicals), 100U Penicillin/Streptomycin (Gibco), 10% hASC conditioned media (LaCell LLC), 10 ng/ml stem cell factor, 10 ng/ml granulocyte stimulating factor, 5 ng/ml FLT-3 ligand, and 5 ng/ml IL-7 (as above). Half of the media was replaced once a week. After 4 weeks, cells were harvested, counted and assessed by flow cytometry using CD34-PE, CD10-Pacific Blue, CD19-PE-Cy5 (BioLegend), CD33-APC (BD Biosciences), and goat anti-ARID3a with a FITC-conjugated anti-goat secondary. Methocult cultures were incubated for 14 days and colonies were analyzed visually for monocytic, granulocytic and erythrocytic lineage cell colonies and counted using a Nikon Eclipse TS100 inverted microscope. Methocult cultures were harvested with warm 1X PBS, washed twice with warm PBS and once with ice cold PBS and then assessed by flow cytometry for the following surface markers: CD34, CD33, CD14, CD16, and CD41 with intracellular ARID3a.

CD34+ hematopoietic progenitors were isolated from mononuclear cells using the EasySep Human CD34 Positive Selection Kit (StemCell Technologies), and plated in triplicate at 10,000 cells per well as described (25 (link), 26 (link)). Briefly, cells were cultured in QBSF®60 (Quality Biological, Inc.) supplemented with 10% FBS (Atlanta Biologicals), 100U Penicillin/Streptomycin (Gibco), 10% hMSC conditioned media (graciously provided by Dr. J. Gimble) and containing stem cell factor, 10ng/ml granulocyte stimulating factor, 5ng/ml FLT-3 ligand, and 5ng/ml IL-7 (R&D). Half of the media was replaced once a week for the duration. After 4 weeks of culture, cells were harvested, counted and assessed for the following markers by flow cytometry: CD34 PE, CD10 Pacific Blue, CD19 PE-Cy5 (all from BioLegend), and CD33 APC (BD Biosciences). For proliferation assays, cells were labeled with CFSE (10μM, Invitrogen) in PBS for 10 minutes, followed by 4X volume of RPMI supplemented with 20% FBS for 5 minutes on ice to quench CFSE uptake. Cells were washed once with RPMI containing 20% FBS, and twice with PBS supplemented with 20% FBS prior to in vitro culture. After 6 days, cells were harvested and assessed for CD34 and CFSE expression levels via flow cytometry.

Gating for individual B cell subsets was described previously [3 (link)] and used with the following B (CD20+) cell subset markers: transitional (IgD+CD27−CD10+), naïve (IgD+CD27−CD10+), MZ-like Memory (IgD+CD27+), Memory (IgD+CD27+), and double-negative (DN) (IgD−CD27−) B cells. Non-B cells were excluded using the following markers on the fluorochrome, APC: T cells (CD3), Monocytes, macrophages, and granulocytes (CD14), NK cells, neutrophils, macrophage and dendritic cells (CD16), and NK and NKT cells (CD56). Isotype controls (Caltag, BD Pharmingen, and eBioscience) were used for gating.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
