Height changes associated with pigment aggregation in Xenopus laevis melanophores.
Melanophores are pigment cells found in the skin of lower vertebrates. The brownish-black pigment melanin is stored in organelles called melanosomes. In response to different stimuli, the cells can redistribute the melanosomes, and thereby change colour. During melanosome aggregation, a height increase has been observed in fish and frog melanophores across the cell centre. The mechanism by whic...
متن کاملProtein kinase C activation antagonizes melatonin-induced pigment aggregation in Xenopus laevis melanophores
The pineal hormone, melatonin (5-methoxy N-acetyltryptamine) induces a rapid aggregation of melanin-containing pigment granules in isolated melanophores of Xenopus laevis. Treatment of melanophores with activators of protein kinase C (PKC), including phorbol esters, mezerein and a synthetic diacylglycerol, did not affect pigment granule distribution but did prevent and reverse melatonin-induced...
متن کاملCell Turnover in the Spinal Ganglia of Xenopus Laevis Tadpoles.
H U G H E S (1961) has drawn up a balance-sheet of the lumbar ventral horn cells during the development of Xenopus, based both on counts of numbers of ventral horn cells throughout differentiation and of the number of degenerating cells among them at each stage. In this way, he showed that the total number of ventral horn cells is reduced from between 3000 and 4000 at differentiation to 1200 at...
