Investigates how matrix and mesangial cell interactions affect macrophage migration, suggesting implications for renal injury.

To determine how interactions between mesangial cells and the matrix influence the migration of macrophages into the mesangium.
Mouse mesangial cells plated on various substrates including collagen and Matrigel
Supernatants collected to assess effects on macrophage migration across a filter
Migration evaluated using modified Boyden chamber technique
Conditioned media from mesangial cells on Matrigel significantly enhanced macrophage migration compared to other substrates
Migration response was dose-dependent with Matrigel interactions
Anti-MCP-1 antibodies reduced macrophage migration while anti-TGF-β antibodies had no effect
MCP-1 mRNA levels were five times higher in mesangial cells on Matrigel than on plastic or collagen

Singhal et al. (1998) studied this question.
