Article Title: Chemoattractive potential of stem cells from apical papilla in peripheral blood monocytes: an in vitro study

doi: 10.1590/0103-644020256694

Figure Lengend Snippet: Production of CCL2 quantified by ELISA assay in SCAP conditioned medium (CM-SCAP). Bars show the mean and standard deviation of the experiment (N=3) (A). Viability of monocytes stimulated with decreasing dilutions of SCAP supernatant (CM) compared with control (proliferation medium alone). Absorbance (570nm) data obtained from the MTT assay after 24 h of stimulus exposure (B). Fluorescence data obtained by Alamar Blue assay at experimental time of 24 h. Conditioned medium by SCAP (CM-SCAP) diluted ½ in the presence or not of a CCL2 neutralizer (CM-SCAP + α-CCL2) compared to control (proliferation medium alone) and Recombinant Human CCL2 (CCL2 rH) (C). The result showed the mean and standard deviation of the experiments performed in triplicate. Different letters represent statistical differences between groups. (One-Way ANOVA with Tukey's test, p<0.05) (B and C).

Article Snippet: 300 ng/ml of Recombinant Human CCL2 (279-MC-010 R&D Systems) was used for positive control, while α-MEM 10% was the negative control.

Figure Lengend Snippet: a. Molecular structure of GalNAz. b. On day 3 post-subculture, transwells were organized into treatment groups such that TEER means were approximately equal and treated with GalNAz or DMSO (vehicle control).Transwells were re-treated on day 6 post-subculture, and the effects on TEER (c), 125 I-CCL2 Pe (d) and 131 I-Alb Pe (e) were measured on day 9 post-subculture. f.
