Fibrocytes have previously been identified as important mediators in several
inflammatory and fibrotic diseases. However, there is no effective treatment thus
far to reduce fibrotic tissue responses without affecting wound healing
reactions. Here we investigate two strategies to alleviate fibrocyte interactions
at the biomaterial interface, reducing collagen production and scar tissue
formation. First, in an indirect approach, TGF-? inhibitor-SB431542 and
IL-1?/TNF-? inhibitor SB203580 were locally released from scaffold implants to
block their respective signaling pathways. We show that the inhibition of
IL-1?/TNF-? has no influence on overall fibrotic tissue reactions to the
implants. However, the reduction of localized TGF-? significantly decreases the
fibrocyte accumulation and myofibroblast activation while reducing the fibrotic
tissue formation. Since fibrocytes can be differentiated into non-fibrotic cell
types, such as adipocytes, we further sought a more direct approach to reduce
fibrocyte responses by directing fibrocyte differentiation into adipocytes.
Interestingly, by initiating fibrocyte-to-adipocyte differentiation through
sustained differentiation cocktail release, we find that adipogenic
differentiation forces incoming fibrocytes away from the traditional
myofibroblast lineage, leading to a substantial reduction in the collagen
formation and fibrotic response. Our results support a novel and effective
strategy to improve implant safety by reducing implant-associated fibrotic tissue
reactions via directing non-fibrotic differentiation of fibrocytes.
