Miltenyi Biotec cd34 cell fractions

Differentiation of <t>CB-CD34+</t> cells in a feeder- and serum-free culture system. A, Schematic of culture system. B, Conceptual schema of human T-cell development. CD7, CD5, and CD1a are sequentially expressed on <t>CD34+</t> cells entering into the thymus (DN cells), and develop into CD4- or CD8-expressing single positive (SP) cells through immature SP (iSP) and immature double-positive (iDP). Finally, mature SP T cells leave thymus and spread to periphery. C, Representative histograms and flow cytometry plots on day 14. Mean ± SEM values are presented for percent of CD7+ and CD7+CD5+ cells. D, The CD7+ (proT1) cell numbers on day 14 were different between groups without AA under ambient air and groups with AA under physioxia. CD7+ cell number showed differences between physioxia and ambient air groups (n = 9, two-way ANOVA, *P < .05, **P < .01). E, CD7+CD5+ (proT2) cell numbers showed differences between ambient air and physioxia groups (n = 9, two-way ANOVA, *P < .05). F, Folds of numbers of CD33+ (myeloid) cells on day 14 (n = 4, *P < .05). Cell numbers were normalized as cell numbers plated into one well (4000 CD34 + HSC/HPCs). Plots are presented as mean ± SEM. H, physioxia; HA, physioxia with AA; N, ambient air (non-physioxia); NA, ambient air with AA; NS, not significant

HSC/HPC populations in physioxia vs ambient air groups. Cell numbers of (A) HSC/HPC (CD34+CD38−), (B) HSC (CD34+CD38−CD45RA−CD90+), and (C) multipotent progenitor (MPP, CD34+CD38−CD45RA−CD90−) were not different between physioxia and ambient air groups. D, Higher numbers of Lymphoid-primed multipotent progenitors (LMPP, CD34+CD38−CD45RA+CD90lo/−CD10−) and multi-lymphoid progenitors (MLP, CD34+CD38−CD45RA+CD90lo/−D10+) were observed in physioxia groups than in ambient air groups (P = .056) on day 7 (n = 3). E, Gene expression of the Notch1 signaling pathway (Notch1, HES1, DELTEX, TCF7, and GATA3) and PU.1 were not differently expressed between physioxia and ambient air groups at 48 hours (n = 4). Data are expressed as mean ± SEM. H, physioxia; HA, physioxia with AA; N, ambient air; NA, ambient air with AA; NS, not significant

Maturation of progenitor T cells on artificial thymic organoid cultures (ATO). A, Experimental schema. B, ATO at week 6. Images of ATOs divided by four or nine pieces at ×10 magnification were taken using inverted microscope (Eclipse Ts2R, Nikon, Tokyo, Japan), then merged those into one images using a large imaging stitching tool with NIS-elements Basic Research software (Nikon). C, Representative flow cytometry plot showing progenitor T cells and T-cell development on ATOs. Week 2 is the timing of placing progenitor cells onto ATOs, and week 6 is the timing for harvesting ATO cells for further analysis. More abundant expression of progenitor T and mature T-cell markers on cells were noted at week 6 than at week 2, with a comparison of cells maintained under ambient air (21% O2) vs under physioxia (5% O2) (n = 3)

Effect of physioxia vs ambient air during the maturation phase in ATOs. A, Experimental schema. B, ATO cell numbers under physioxia (5% O2) were increased more than those under ambient air (21% O2). Cell numbers were normalized by cell numbers placed onto one ATO (7500 progenitors/ATO) and cell numbers plated into one well (4000 CD34+ cells/well) (n = 3, two-way ANOVA, *P < .05). C, Cell numbers of CD7+CD1a+ precursor T cells per 4000 CD34+ cells between physioxia vs ambient air groups in ATOs (n = 3, two-way ANOVA, **P < .01). D-F, Numbers of T-cell subsets per 4000 CD34+ cells between physioxia vs ambient air groups in ATOs on week 6 (n = 3, two-way ANOVA, *P < .05). Data are presented as mean ± SEM. Diff., Differentiation; Mat., Maturation; NS, not significant
