 ls or higher organisms by means of diffusive compounds is an important phe
 nomenon in biological systems. A straightforward model is by a diffusion e
 quation with suitable flux boundary conditions at the cell boundaries. Suc
 h a model will become computationally inefficient and analytically complex
  when there are many cells\, even more so when they are moving. We propose
  to consider also a point source model. Each cell is virtually reduced to 
 a point and appears in the diffusion equation for the compound on the full
  spatial domain as a singular reaction term in the form of a Dirac delta m
 easure located at the cell’s centre. The amplitude of the Dirac delta me
 asure is a nonlocal term of the compound’s concentration near the virtua
 l cell boundary so as to preserve the essential biological features. To in
 vestigate the positivity of the solution and the structure of steady state
 s\, we employ the Laplace transform. In addition\, the theory of elliptic 
 curve is also involved.
