Table 3.

Cell motility processes are formulated in terms of reactant-catalyst-product (RCP) processes. The table includes the RCP-processes that are used to describe random cell movement of growth factor-producing ($s_1$) and non-producing ($s_2$) cells

Biological process	Reactants (r), catalysts (c), products (p)	Markov operator	Description
Jump$[s_1,M_1(x_1-x_2)]$	$\mathbf{r}=\{x_1,s_1\},$ $\mathbf{c}=\mathrm{\varnothing },$ $\mathbf{p}=\{x_2,s_1\}$	$L_M^{s_1}$	A cell with mark $s_1$ in location $x_1$ jumps to location $x_2$ with kernel $M_1(x_1-x_2)$
Jump$[s_2,M_2(x_1-x_2)]$	$\mathbf{r}=\{x_1,s_2\},$ $\mathbf{c}=\mathrm{\varnothing },$ $\mathbf{p}=\{x_2,s_2\}$	$L_M^{s_2}$	A cell with mark $s_2$ in location $x_1$ jumps to location $x_2$ with kernel $M_2(x_1-x_2)$
