    Both CD161 + and CD161 - ProTcell subsets retain T and NK cell potential as well as thymus seeding ability. (A–E, G, H) ProTcells were produced from CB CD34 + cells in 7 days as indicated in <xref ref-type= Figure 1A and sorted by FACS regarding their CD161 expression for further NK or T cell differentiation and functional in vivo experiment. To ensure the consistency, we used the same cell lot and the same sorted cell populations to perform the experiments shown in this figure, including NK cell differentiation, T cell differentiation, and the in vivo engraftment assay. (A) Experimental scheme for CD7 + CD161 - (red frame) and CD7 + CD161 + (green frame) cell subset sorting before NK or T cell differentiation. Differentiating cell phenotype was assessed by flow cytometry. (B, C) CD7 + CD161 +/- lymphoid progenitors were cultured for 14 days in the presence of IL15 without any feeder cell for NK differentiation. Bar plots represent the mean ± SD of (B) the proportion and (C) number of CD56 + NK-primed cells in the culture. (D, E) CD7 + CD161 +/- lymphoid progenitors were co-cultured for 4 weeks with OP9-DLL1 to advance T cell differentiation. Line plots depicting the mean ± SD of the (D) proportion and (E) number of CD3 + developing T cell throughout the culture. *p<0.05 values are for multiple paired Student’s t-test. (F) ProTcells were produced from mPB and CB CD34 + cells and their protein expression (CyTOF) was assessed in a single cell fashion, and restricted to CD7 + progenitors, as described in Figures 1A, B . CyTOF data was visualized by UMAP dimension reduction technic. UMAP projections illustrate the protein expression of several adhesion/homing molecules CCR9, CCR7, CXCR4, CD44, CD62L, SELPLG, ITGA4 and ITGB4. The black line separates the CD161-enriched from the CD161-devoid cells. (G) CD7 + CD161 - or CD7 + CD161 + cell subset has been injected separately into NSG neonates (<4-day-old). T cell reconstitution was analyzed by flow cytometry in the thymus at 6-week-post-transplantation.

    Figure Lengend Snippet: a Ex vivo expansion and b degranulation capacity of NK cells from PB of patients with FL and healthy donors ( n = 6). c Transwell migration of Sham (no mRNA) and hCCR7 mRNA-modified NK cells against gradients of CCL19 6-8 hours after electroporation ( n = 6). d Viability and expression kinetics of CCR7, CXCR5, CD62L, and CD16 molecules on ex vivo expanded human NK cells from FL patients after mRNA electroporation compared to Sham (no mRNA) ( n = 2). e Transwell migration of Sham (no mRNA) and mRNA-electroporated NK cells from two FL patients against gradients of one or several chemokines 6–8 hours after electroporation. f Degranulation capacity of NK cells from two patients with FL against different target cell lines 24 hours after mRNA electroporation compared to Sham (no mRNA). g Representative example of degranulation capacity of ex vivo expanded human NK cells from a lymphoma patient against autologous LN fine-needle biopsy material containing primary tumor cells after electroporation with Sham, CCR7, CXCR5, CD62L or additionally CD16-158V mRNA. The Mann-Whitney U test was used for statistics in a and b .

    Article Snippet: Custom-made mRNAs encoding for human CCR7 and CXCR5 were obtained from TriLink Biotechnologies. mRNAs encoding for human CD62L and mouse CCR7, CXCR5, and CD62L were prepared from plasmids purchased from SinoBiological: (human CD62L (HG11838-UT), mouse CCR7 (MG50873-UT), mouse CXCR5 (MG50843-UT), mouse CD62L (MG50045-UT)) using the HiScribe T7 ARCA mRNA Kit (with tailing) and the MEGAclear™ Kit (Invitrogen) according to the manufacturer’s instructions.
