Peripheral mononuclear cells (PBMCs) were isolated through Ficoll-Paque density gradient. 2×106 PBMCs were stained for phenotypic analysis with the following fluorochrome-conjugated
antibodies: CD3-V500 (BD Biosciences), CD4-APCeF780 (eBiosciences), CD8-BV605 (Biolegend), CD28-PE-Cy7 (Biolegend), CD38-APC (eBiosciences), CD45RO-FITC (eBiosciences), HLA-DR-AF700 (eBiosciences), CD45RA-PerCP-Cy5.5 (Biolegend). Viability was determined with Live/Dead fixable blue dead cell stain (Invitrogen). Intracellular stain was performed with FoxP3-Pacific Blue (eBiosciences) and Ki-67-BV786 (BD Biosciences) following the eBiosciences Fixation/Permeabilization protocol (Invitrogen). Samples were analyzed on a BD LSRFortessa analyzer (BD Biosciences). Flow cytometry data analysis was done with FlowJo V10, LLC Software.

Isolation and Characterization of CD34+ Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
The umbilical cord blood was collected from normal full-term delivery after obtaining informed consent from the mothers as a donation for banking, and only cord blood samples not appropriate for banking (< 100 ml) were used in our experiments. The procedures of isolation and characterization of CD34+ cells were performed as we earlier described in Zhao’s article [7 (link)]. The phenotypic characterization on CD34+ cells was assayed using the flow cytometer for CD34-PCY7, CD45-FITC, and CD38-APC (eBioscience, San Diego, USA). The percentages of CD34+ cells and CD34+CD38− cells were 0.952 ± 0.025 and 0.105 ± 0.070 for each cord blood unit (mean with SD, n = 4).

CD34+ cells were labeled with CD34-PeCy7, Lin-APC-Cy7 (including CD2, CD3, CD7, CD10, CD19, and CD235a), and CD38-APC or CD38-PE, CD90-PercpCy5.5, CD123-APC, or CD47-APC (eBioscience) antibodies; fixed and permeabilized (Cytofix/Cytoperm Kit, Beckman Coulter); labeled with rabbit anti-human SIRT1 (E1104-1, Millipore) and Alexa Fluor 488-conjugated goat anti-rabbit antibodies (Invitrogen); and analyzed by flow cytometry. Data were analyzed using FlowJo software (version 8.5.2; TreeStar).

To determine the NK cells and lymphocyte subsets in patients, heparin‐anticoagulated whole blood samples were collected and stained with (1) CD3‐PerCP (BD Biosciences, San Jose, CA,), CD4‐BV510 (BD Biosciences, San Jose, CA), CD8‐APC (BD Biosciences, San Jose, CA), CD45RO‐BV421 (BioLegend, San Diego, CA), and CCR7‐PE (BD Biosciences, San Jose, CA); (2) CD4‐APC‐Cy7 (eBioscience, San Diego, CA), CXCR5‐APC (eBioscience, San Diego, CA), TIM‐3‐PerCP (eBioscience, San Diego, CA), TIGIT‐FITC (eBioscience, San Diego, CA), CD226‐PE‐Cy7 (eBioscience, San Diego, CA), PD‐1‐BV510 (BD Biosciences, San Jose, CA), and ICOS‐BV421 (BD Biosciences, San Jose, CA); (3) CD19‐PE (eBioscience, San Diego, CA), CD27‐PE‐Cy7 (eBioscience, San Diego, CA), CD38‐APC (eBioscience, San Diego, CA), CD24‐APC‐Cy7 (eBioscience, San Diego, CA), IgM‐BV421 (eBioscience, San Diego, CA,), and IgD‐FITC (eBioscience, San Diego, CA); and (4) CD3‐FITC (BD Biosciences, San Jose, CA) and CD16 + CD56‐PE (BD Biosciences, San Jose, CA). Cell counting was performed with absolute counting tubes with a certain number of beads (BD Biosciences, San Jose, CA). The samples were measured using FACS Canto II (BD Biosciences, San Jose, CA). Gating analysis was performed with FlowJo V10 (BD Biosciences, San Jose, CA).

Enumeration of Hematopoietic Stem Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
At day 10, we harvested the nonadherent and adherent cells from five different culture conditions, and the total nucleated cells (TNCs) counted via trypan blue staining method. Flow cytometry staining was performed with CD34-PECY7, CD45-FITC, and CD38-APC (eBioscience, San Diego, USA) antibodies, then samples were analyzed using a FACScan flow cytometer (Beckman Coulter, USA). For each sample, at least 10,000 events were recorded. The isotype antibodies were used to determine the level of nonspecific binding.

Allogeneic T cell proliferation assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
Donor and recipient PBMCs were thawed and rested for 1 hour in media with DNase I (Roche). For stimulators, APCs were isolated from donor PBMCs with CD3 MicroBeads (Miltenyi Biotec). For responders, recipient PBMCs were stained with CellTrace™ Violet Cell proliferation dye (ThermoFisher Scientific). 3×104 recipient responder PBMCs were cultured for 5 days in serum-free AIM V media with 8×104 isolated stimulator APCs from donor PBMCs. Cells were then washed with PBS, blocked with Fc Block, stained for surface markers CD3-V500 (BD Biosciences), CD4-APCeF780 (eBiosciences), CD8-BV605 (Biolegend), CD28-PE-Cy7 (Biolegend), CD38-APC (eBiosciences), CD45RO-FITC (eBiosciences), (eBiosciences), and CD45RA-PerCP-Cy5.5 (Biolegend). Viability was determined with Live/Dead fixable blue dead cell stain (Invitrogen). Samples were analyzed on a BD LSRFortessa analyzer (BD Biosciences). Flow cytometry data analysis was done with FlowJo V10, LLC Software.

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.
