“…The present observations on the various types of chromatophores in the reptile Trionyx sinensis such as the melanophores, iridophores and xanthophores coincide well with previous observations on the amphibians and fishes (BAGNARA and HADLEY, 1969;BAGNARA and TAYLOR, 1970;BAGNARA, FERRIS and TAYLOR, 1976; MATSUMOTO, 1978;OHSUGI and IDE, 1983;FROST, Epp and ROBINSON, 1984a, b;FROST and ROBINSON, 1984 et al, 1979b) in fish (TURNER, TAYLOR and TcHEN, 1975) and in the red-spotted newt (FORBES, ZACCARIA and DENT, 1973), and have also been recently reviewed (BAGNARA, 1983). BAGNARA et al (1979a) has postulated a common origin for pigment cells from a stem cell containing a primordial organelle with the potential of becoming any of the three pigments described, such as the melanosomes of the melanophores, reflecting platelets of the iridophores and pterinosomes of the xanthophores.…”

“…We observed that pigment cells occurring in a blue mid‐dorsal stripe of the garter snake were installed with numerous peculiar organelles which differed in their intragranular ultrastructure from typical pterinosomes (16). In 1995, Dr Fujii reported the presence of cyanosomes, the organelles attributable to blue pigmentation in fish (18).…”

This is a biographical sketch of my research and its related personal episodes with respect to brightly colored pigmentation in lower vertebrates. It includes a brief story of the studies on; (a) pterinosomes as a specific site of pteridine deposition in xanthophores or erythrophores of fish and amphibians, (b) a mosaic phenotype of chromatophores occurring in the reptiles and its implication for their developmental origin and differentiation mechanisms, (c) erythrophoroma as a tumor of erythrophores in goldfish, (d) the pluripotentials of erythrophoroma cells for expression of neural crest-derived characters in vitro, (e) pigment disorders occurring in hatchery-raised flounders and (f) recognition of pigment cell types by murine tyrosinase genes transfected into an orange-colored variant of medaka fish. Some of the personal affairs associated with the history of the Japanese community for pigment cell research were described to illustrate the background of these studies.

“…Not only does allopurinol treatment produce a phenocopy of the melanoid mutant but, biochemically, the pteridine pigment pattern is nearly identical for both true melanoids and drug-induced phenocopies [61]. Analogous experiments involving wild-type Drosophila produced phenocopies of the rosy mutant [62,63].…”

The Mexican axolotl (Ambystoma mexicanum) provides a well-defined set of color genes which are useful for various types of analyses. These include the a (albino), m (melanoid), ax (axanthic), and d (white) genes. In addition, various combinations of these genes and a number of as yet undescribed mutants also exist. Three of these mutants (a, ax, and m) have defects associated with specific neural-crest-derived pigment cell types. The fourth mutant ( d ) appears to provide an unsuitable environment for the migration and maintenance of pigment cells. In one case ( m ) , detailed information concerning the specific nature of the genetic defect is available.The goal of this article is to demonstrate ways in which the existing information on the axolotl color genes can best be utilized in terms of understanding not only the mutant phenotypes, but basic concepts in the cell and developmental biology of pigmentation as well. Thus, an attempt has been made to sort through the genetic and biochemical data relevant to these mutants in order to stimulate renewed interest in a more detailed pursuit of such studies.
