Jones' Human Mucosal Cells

Jones’ human mucosal cells, initially healthy and cultured in petri dishes, become the unwilling subjects of the mutagenic experiment. Under the microscope, their transformation into maggot-like tissue provides irrefutable evidence of the contamination’s mechanism, horrifying Jo and validating the Doctor’s urgency.

Jones' mucosal cells serve as the controlled experimental medium under a microscope slide, directly confirming the maggot's mutagenic capability. When examined post-exposure to the maggot's green slime trail (represented by the Doctor's 'green cells'), they visibly transform into hybrid cellular monstrosities. The cells thus become physical evidence of Global Chemicals' biological contamination.

The specimen dishes containing Jones’ mutated human mucosal cells lie open on the workbench, their once-sterile glass now compounded by urgency. The Doctor’s half-turn toward Nancy interrupts their examination, leaving the warped tissues untouched and their implications still raw. Their silent testimony to the maggot’s cellular invasion becomes a condemnation of Global Chemicals’ timeline.
