Figure Lengend Snippet: Characterization of hDPSCs. A Light microscopy images of primary hDPSCs on 9th day. B Image of hDPSCs colony forming units at 14 days. C Alizarin red staining of mineralized nodules. D Oil red staining of adipogenic induction. E Alcian bale staining of chondrogenic induction. F Flow cytometric analysis of hDPSCs using multiple markers. hDPSCs were positive for CD73, CD90, and CD105, and negative for CD34 and CD45. G Positive immunofluorescence to nestin and stro-1, and negative to cytokeratin-3 of hDPSCs

Article Snippet: Primary antibodies included rabbit anti-human nestin (Affinity Biosciences, China), mouse anti-human stro−1 (R&D systems, USA) and mouse anti-human cytokeratin (Abcam, USA).

Figure Lengend Snippet: Optimization of culture conditions. a Viable and non-viable regulatory T cells (Treg) from one donor cultured in RPMI or TexMACS media, with and without starvation, at days 14 and 21. b Characterization of Treg cultured in TexMACS or RPMI with and without starvation, at days 14 and 21. c Phalloidin staining for F-actin (red), DAPI staining for nuclei (blue), and STRO-1 expression (green). Scale bar: 50 μm. d Metabolic activity of bone marrow mesenchymal stromal cells (BMSC) cultured in growth media (GM) or TexMACS. Data are presented as mean ± standard error of mean from three independent donors ( n = 3) * p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001, **** p ≤ 0.0001

Article Snippet: Cells were fixed with 4% paraformaldehyde (Sigma-Aldrich) for 10 min, permeabilized (Invitrogen) for 30 min, and blocked with 3% BSA and 10% Normal Goat Serum (Thermo Fisher Scientific) in DPBS for 1 h. Cells were then incubated overnight at 4 °C with anti-STRO-1 antibody (1:150) (Santa Cruz Biotechnology, USA) in 3% BSA/DPBS, and followed by Alexa FluorTM 488 secondary antibody (1:200) (Thermo Fisher Scientific) in DPBS for 1 h. Nuclei and cytoskeleton was stained with DAPI (1:1000) (Thermo Fisher Scientific) and Phalloidin Atto 565 (1:500) (Sigma-Aldrich) in DPBS for 1 h. Images were taken by Dragonfly 505 confocal microscope (Andor Technologies Inc, Northern Ireland).
