Continuous cell production
The two previous
experiments demonstrated a three CA system which produced a fruit
that later on died. The present experiment describes a system which
continually produces cells. CA-1, the stem process controls CA-2 differentiation and supplies it with age (resources).
In addition it senses when a process dies, and plants a zygote instead (marked by an arrow). CA-3 triggers CA-2 blossoming, and supplies it with age.
The curve
depicts CA-2 maximal
age. Whenever the age of a
CA-2 cell hits max age = CA-3[mean age], it dies and is excreted into the
environment. Compare with the
previous chapter where CA-3[mean age] was depicted.
Each differentiation event produces one cell.
The troughs marked with an asterisk, mark the planting of a new zygote initiated
by the stem process (CA-1). The age of most zygotes is zero. Some, like
the second zygote inherit their age from the dying process.
The curve below depicts maximal ages of the three CA. Maximal
age of CA-1 is constant since it donates its age increment to CA-2. The
age of CA-3 which triggers blossoming declines. When it dies it is replaced
with a zygote.
The lowest curve depicts the age of the dead cells. Each
peak is a differentiation event. The older a dead cell the more resources
it has for the benefit of other processes. The longer the interval between
two differentiation events the better the cell quality.
