== Incubation system ==

MAS-GE 1999 formed the liquid environment of the standard Snubable incubation system. A developing clone remained submerged throughout physical maturation. Pumps circulated the medium through a conditioning unit that maintained temperature and corrected changes in pH. Filters removed suspended biological material, and part of the fluid was replaced when filtration could no longer maintain the required conditions.

Early physiological exchange occurred through temporary placenta-like tissue produced from the same reprogrammed source population as the clone. The system changed to direct vascular support after blood flow and cardiac performance reached the required state. Tissue oxygenation provided a further measure of readiness. The change therefore did not occur on a fixed incubation day.<ref name="a-series-gestation"/>

The lungs remained fluid-filled during incubation. The vascular interface oxygenated the blood until removal from the chamber, when lung-fluid clearance and the first breaths began. Neural stimulation operated separately to standardize nervous-system development. Under mature factory conditions, the complete system could produce a physically mature clone in approximately 14 days.<ref name="a-series-gestation"/>
