Based on paper : Meyburg et.al. 2009 One Liver for Four Children: First Clinical Series of Liver Cell Transplantation for Severe Neonatal Urea Cycle Defects
( DOI: 10.1097/TP.0b013e318199936a ) : "The cell suspension was applied manually over 20 to 60 min per session and was gently shaken during the procedure to avoid cell sedimentation." Sedimentation must be avoided during process of cell transplantation.

This process can be improved by supplying mounting for syringe pump that set-up vertically using KDS LEGATO 110 SINGLE SYRINGE INFUSE/WITHDRAW PROGRAMMABLE ( http://www.kdscientific.com/products/pumps/legato110.asp )

The mounting is attach to ceiling wall of operating table that leveled by water pass to ensure vertical setup.

This simple setup eliminate sedimentation effect in injection process of cell transplantation.
