The effects of iris-ciliary complex on the organ cultured rabbit ocular lens.
Freshly isolated rabbit lenses were cultured with and without attached iris-ciliary (IC)-complex for 24 hours in TC-199 medium. Subsequent morphological analysis revealed that the IC-complex cannot be maintained in serum-free medium. In addition an observed effect of the IC-complex on the co-cultured lenses could not be due only because of the cellular degeneration of the IC-complex. To test this possibility lenses with attached IC-complexes were incubated in 20% serum-containing TC-199 medium. The IC-complex cultured in 20% serum containing medium retained its normal morphology. However co-cultured lens cells displayed vacuoles and other signs of degeneration. The protein synthetic and Na+/K+ pump activities of these lenses were also significantly depressed. These data indicated that the observed effects of IC-complex on the lens were not due to its cellular degradation. Preliminary experiments showed that the IC-complex contains water soluble factor(s) which could effectively inhibit lens protein synthesis and Na+/K+ pump.
