Computer Analysis of Oscillatory Features of the Red Cell System
233
BETZ:
In every case when in your figures the frequencies of stem cells and red cells are
different, there seems to be some interference of two oscillations in the case of
the stem cells. Perhaps there would be no difference in frequency if we could
account for this second, less pronounced mode of oscillations.
KIRK:
In figure 3 the second mode of oscillation is composed of at least two components of different frequencies and this accounts for the interference or
beating effects observed.
BETZ:
In one of your figures there is a phase difference between stem cells and red
cells. May this difference be due to the time difference needed for differentiation of the red cells?
KIRK:
Yes, this difference in phase represents the time for a differentiated stem cell
to pass through the normoblast series and become a mature red cell.
WALTER:
What is the range of Z in your equation?
KIRK:
Z is of the order of 9.
