Effects of intraocular irrigating solutions on the spreading of rabbit corneal endothelial cells on extracellular matrices.
The effects of four commercially available irrigating solutions on the spreading of rabbit corneal endothelial cells on various extracellular matrices were studied. Cultured rabbit corneal endothelial cells, suspended in one of the following intraocular irrigating solutions, Opeguard MA, BSS, BSS Plus, lactated Ringer solution (Lactec) or physiological saline, were placed on uncoated tissue culture plates or on plates coated with extracellular matrices (fibronectin, laminin, collagen type I, or collagen type IV). The cell area was measured after 45 minutes' incubation. The cells spread on all of the extracellular matrices examined but not on the uncoated tissue culture plates. On the fibronectin or laminin matrix, the cell area was significantly greater with Opeguard MA or BSS Plus. On laminin and collagen type IV, the cell area was the greatest with Opeguard MA. On collagen type I, the cell area was significantly greater with Opeguard MA, BSS, or BSS Plus. These results demonstrated that the rabbit corneal endothelial cells responded to the extracellular matrices, and that Opeguard MA or BSS Plus provided more favorable conditions for the spreading of these cells. These results indicated that both Opeguard MA and BSS Plus might aid the spreading of corneal endothelial cells during wound-healing immediately after intraocular surgery.
