[Histochemistry of the ball cell in larval epidermis of Xenopus laevis Daudin].

Presented investigations of chemical composition and metabolism of ball cell in larval epidermis of Xenopus point to a regressive shape of cell corresponding to former light and electron microscopical findings. The lower requirements of energy of this cell are covered by glycolysis and possibly by pentose phosphate cycle. Our hypothesis of pressure-elastic ball of cell as structural element of larval epidermis could been further supported.
