However, the rapid burial of Dakota in a waterlogged, low - oxygen environment allowed fossilisation to outpace the
normal processes of microbial decay,
preserving areas of soft tissue.
However, the morphology of the host inner retinal cells was well -
preserved in the
area of donor cell migration, as evident from the PKCα antibody staining, which labeled
normal - appearing rod bipolar cell dendrites (upward arrows in Figure 6B).
