Induction of neural differentiation in cultures of undetermined presumptive epidermis from three amphibian species was achieved by the addition of 1 millimolar dibutyryl adenosine 3',5'-monophosphate, 8-bromadenosine 3',5'-monophosphate, or adenosine

Adrenal cortex mitochondria prepared by a standard method do not exhibit malic enzyme activity. Addition of physiological concentrations of Ca2+ and Mg2+ enables these mitochondria to reduce added NADP+ by malate to form free NADPH. Half-maximum acti

Triton-insoluble cytoskeleton of nonpigment cells has bound protein kinase that phosphorylates, with or without added cAMP, tubulins and the intermediate filament proteins p60, p56, p53, and p45a to give multiple charge variants. In the absence of 8-

The effects of lumicolchicine, colchicine, vinblastine and cold temperature on the pigment migration in melanophores and xanthophores of Fundulus heteroclitusand Oryzias latipeswere examined by light and electron microscopy. Xanthophores of both spec

Biochemical and ultrastructural studies indicate that the atrophy of adrenal cortex in hypoyhysectomized rats involves the following changes: (1) One to two days after hypophysectomy, there is loss of "template activity" resulting from cumulative DNA

Melanosome formation in differentiating melanophores of embryonic and adult xanthic goldfish was studied by cytochemical methods at the ultrastructural level. Large vesicles (0.4–0.5 μ m) are blebbed from rough endoplasmic reticulum. Golgi-derived

Evidence is presented for the following hypothesis dealing with dibutyryl-c-AMP induction of neural differentiation in Pleurodeles waltlii embryos: (1) Dibutyryl-c-AMP induces the determination for neural differentiation. (2) Additional dibutyryl-c-A

Classical light microscopic studies on pigmentation of Fundulus heteroclitus (killifish) indicated that there are three groups of light reflecting cells; one group on the surface of scales reflects white light, while two other deeper groups (the mela
