[Cell cycles in the early embryogenesis of the peled].
The dynamics of cell cycles in early embryogenesis of the peled has been studied using various methofs: determination of mitotic and mitotic phase index, of cell doubling time and of coefficient of asynchrony. The desynchronization of divisions begins at the V division after the longitudinal furrow has passed and is completed after the beginning of the cell cycle lengthening. The animal-vegetative gradient in the distribution of mitotic phases is observed at the early stages of desynchronization. The lengthening of cell cycle begins in interphase of the XI-XII cleavage and markedly accelerates from the interphase of the XII-XIII cleavage on. The methods of analysis of the cell cycles in early embryogenesis and possible factors influencing the dynamics of desynchronization are discussed.
