B19V-induced wound healing, invasion and MMPs in NHDFs cultures

NHDFs were incubated with B19V-viremic plasma I700, with anti-B19V antibody-treated I700 or with B19V negative serum (mock) and with recombinant virus (B19V-EC), withanti-B19V-treated B19V-EC or with M199 (mock). (A) Wound healing: values are given as percentage of wound closure from four experiments. (B) Invasion: values are given as number of invasive cells from two independent experiments, in triplicate. *P<0.05 vs NHDFs mock control, ^#P<0.05 vs B19V-infected NHDFs. (C) MMP2 and MMP9 activities by gelatine zymography. Results are reported as densitometric units [mean of three different experiments (S.d.)]. *P<0.05 vs mock control NHDFs.
