How long after death could these cells
be harvested? Does the cause of death matter?
The study of the harvest of neural precursors from post-natal
post-mortem brain is also only in its infancy. Unlike fetal
cases, where the post-mortem interval and the cause of death
are relatively tightly controlled, cases of post-natal death
have associated with them many uncontrollable variables.
These uncontrollable variables include but are not limited
to: how soon after death the brain can be removed and the
harvest of cells begun; the age of the deceased; the nature
of the underlying disease of the deceased; the agonal events
surrounding death; the nature of the drug therapies that might
have been present at or near the time of death; the nature
and extent of infectious processes that might have been present
at or near the time of death; etc. Because of this, we cannot
say at this time which of these factors are going to influence
that success or failure of an attempt to harvest neural precursors.
