[Biomicroscopic aspects of normal iris tissue in culture (author's transl)]

The cells shown were cultivated from iris pieces of 1-5 mg wet weight incubated in TCM 199 after adding 20% calf serum and antibiotics. Different morphologic aspects allowed some coordination of the cells to the corresponding iris layer. Even after 1 year's incubation, fibroblastic stroma cells showed a radiate growth from the insemination point. Pigment cell-like elements were packed with yellowish, bright, and intensely refracting spherical bodies, indicating a specific function. An analogous finding in the human eye after a perforating iris lesion was growth of chromatophores on the anterior lens capsule.
