Fig 2. Liver fluke granulin promotes wound repair and angiogenesis.

Fig 2

Opisthorchis viverrini secretes a growth factor termed liver fluke granulin, Ov-GRN-1, an orthologue of mammalian granulin. Ov-GRN-1 stimulates cholangiocytes to proliferate and promotes wound healing and angiogenesis. A recent report on Ov-GRN-1 [32] illustrates some of these carcinogenic-conducive properties of the growth factor, as follows: (A) rate of wound closure on a cutaneous lesion on mice, (B) the angiogenic nature of Ov-GRN-1 revealed using the chorioallantoic membrane assay in fertilized quail eggs.
