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.
