CTGF enhanced the recruitment of PBMCs. a Schematic diagram of the Boyden chamber assay. b Effects of CTGF treatment on the chemotactic migration of PBMCs cocultured with RA. Number of invaded PBMCs during co-culture with RA was indicated on vertical axis. Results are expressed as the mean ± S.E. *p < 0.05 and **p < 0.01.
