How are the Stem Cells stored?
The stem cells are separated into two cassettes
for storage, so that there are potentially two opportunities
for use of the cells. The Stem Cells are put into
cryogenic storage, which is the process of putting
them into a state of ‘suspended animation’,
and keeping them in the vapour stage of liquid nitrogen.
Initially they are put into a controlled freezer
where the temperature is lowered gradually to prevent
damage to the cells. They are then transferred to
the storage freezer where they are kept
at -170ºC. |

How long are the Stem Cells stored for?
Umbilical Cord Stem Cells have successfully been
stored for 15 years, and other Stem Cells have been
stored for longer. Scientists believe that potentially
Umbilical Cord Stem Cells can be kept in cryogenic
storage indefinitely.
How can I get access to the Stem Cells if
they are needed?
The stem cells must be requested by a medical practitioner.
The stem cells are given a unique identification
number so that the they are easily retrieved.
How long has CellSense been collecting Cord
Blood in Australia?
Cellsense has been in operation for nearly 3 years
and has about 1500 Cord Blood Stem Cell Collections
stored.
What happens if there is a power cut at
the laboratory?
This is not a problem because the freezers can work
for 7 days without mains power due to a battery
system. However if the power should fail there is
an alarm system which as well as alarming in the
laboratory, sends an alarm to a pager, which is
carried by laboratory staff 24 hours a day. Therefore
any power cut is dealt with as soon as possible.
What happens to the Stem Cells if Cellsense
goes out of business?
Cellsense is owned by Alexanders Securities, which
is a publicly listed company, and therefore Cellsense
has all of the statutory protection afforded to
it through Australian company law.
As well as this we have a partnership with Sydney
Advenstist Hospital, where the cord blood is processed
and the stem cells are stored. A long term storage
agreement and forward storage payment will mean
that these stem cells will be safe. |
