Structural changes in the pars intermedia of the cichlid teleost Sarotherodon mossambicus as a result of background adaptation and illumination
Summary The pars intermedia of Sarotherodon mossambicus contains two structurally different endocrine cell types. The predominant cell type is assumed to synthesize MSH and related peptides. The second cell type is PAS positive; its function and products are unknown. In this second cell type changes...

The second cell type is PAS positive; its function and products are unknown. In this second cell type changes occur in relation to background colour and illumination. Thus, PAS positive cells of fish adapted to a white background are less numerous and metabolically less active than those of fish adapted to a black background, and are most active in fish kept in total darkness. In blinded fish, whether in light or in darkness, the activity of the PAS positive cells is similar to that of the black background-adapted animals. The significance of these responses in relation to the control of background adaptation is discussed. | ||

abstract |
Summary The pars intermedia of Sarotherodon mossambicus contains two structurally different endocrine cell types. The predominant cell type is assumed to synthesize MSH and related peptides. The second cell type is PAS positive; its function and products are unknown. In this second cell type changes occur in relation to background colour and illumination. Thus, PAS positive cells of fish adapted to a white background are less numerous and metabolically less active than those of fish adapted to a black background, and are most active in fish kept in total darkness. In blinded fish, whether in light or in darkness, the activity of the PAS positive cells is similar to that of the black background-adapted animals. The significance of these responses in relation to the control of background adaptation is discussed. |
