As the number of B cells increases, T helper cells send a signal to start the production of antibodies.
After the 1999 mail bombs, FAI cells sent a torrent of incendiary explosive devices to organizations and journalists such as La Razón newspaper in Madrid, the church of Sant'Ambrogio, the court of Valencia, the Madrid Cathedral, and the Carabinieri (the national military police of Italy) in Genoa, which detonated and wounded one of the policemen.

Superficial pyramidal cells send a halo of excitatory connections laterally in a circle with radius 0.5 mm.
Notch signalling is unidirectional and it is mediated by Delta-expressing cells sending a signal and Notch-expressing cells receiving it.
At stage 7 of oogenesis, posterior follicle cells send a signal back to the oocyte that polarizes the oocyte's MT cytoskeleton, a prerequisite both for the migration of the oocyte nucleus to a point along the oocyte's anterior cortex [31], and the transport of bicoid, oskar and other mRNA that encode embryonic patterning determinants to specific ends of the oocyte [2], [4].
In response, Schwann cells send a signal to interneuromast cells that inhibits their precocious differentiation into neuromasts.
Within the alveolar space, this would seemingly take the form of stretched epithelial cells sending a signal to AMs.
In this context, as for many synthetic biology applications, having even a low proportion of cells sending a signal too early or too long might compromise the correct functioning of the whole system.
