[Dragonball] Humans shed cells all the time, cells regeneration only requires a few cells, how is it even possible to kill him in the first place as wouldnt he have cells just lying around?

Skin cells are already dead when you shed them, so presumably everything outside the gigantic Kamahameha was already dead by the time Cell got blasted.  

They can't stay alive and viable for regeneration indefinitely, otherwise there would be a
million Cell clones hanging out within a week or two.  Sorta like an Ork infestation.
