Figure Lengend Snippet: a Transendothelial migration of REH cells across HUVEC monolayers toward CXCL12 (100 ng/mL, 4 h) following treatment of only REH cells with TubA (TubA; 20 µM, 1 h) or DMSO. Unpaired two-tailed Student’s t test; n = 3. b Dynamics of F-actin polymerisation in REH cells pretreated with TubA or DMSO and stimulated with CXCL12 for the indicated times. Cells were immediately fixed and stained with phalloidin. Data are shown relative to time 0 (set to 1; dotted line).

Data are shown as MFI ± standard deviation. * p < 0.05; ** p < 0.01; *** p < 0.001; **** p ≤ 0.0001; ns not significant.

Article Snippet: The B-ALL cell lines REH (ATCC, CRL-8286) and RS4:11 (ATCC, CRL-1873), and the stromal cell line HS5 (ATCC CRL-11882) were cultured in RPMI-1640 or DMEM (Sigma/Merck), respectively, supplemented with 10% foetal bovine serum (FBS).
