ViaCell Announces Expansion of ViaCord
                       Processing Laboratory



   CAMBRIDGE, Mass.--Sept. 18, 2007--ViaCell, Inc. (Nasdaq: VIAC)
today announced that it is expanding its ViaCord Processing Facility
(VPL), the Company's state-of-the-art cord blood processing and
storage facility. The expansion of VPL will support anticipated future
demand of ViaCord(R), its product offering for the preservation of
cord blood. ViaCell will conduct renovations in the newly leased space
in order to meet its planned cord blood processing and storage needs
for the coming years. The expansion is expected to be completed in the
first quarter of 2008.

   "The expansion of our cord blood processing facility will more
than double our storage capacity and positions us to meet increasing
demand for ViaCord," said Jim Corbett, President of ViaCell
Reproductive Health.

   ViaCord has been successfully processing cord blood since 1995 and
processing cord blood at VPL since 2002. This facility is AABB
accredited and incorporates industry-leading standards, including a
closed processing system, storage of cord blood with multiple attached
segments, use of the only-FDA cleared process automation equipment and
laboratory testing performed in accordance with Clinical Laboratory
Improvement Amendments (CLIA) regulations.

   About Umbilical Cord Blood

   Umbilical cord blood is a valuable, non-controversial source of
stem cells with proven therapeutic effect in treating over 40
diseases. These diseases include various forms of cancer, such as
Acute Lymphoblastic Leukemia (ALL) and Non-Hodgkin's lymphoma; certain
bone marrow failure syndromes, such as severe aplastic anemia and
Diamond Blackfan anemia; certain blood disorders such as sickle cell
anemia, thalassemia; and other genetic disorders. Over 8,000 cord
blood transplants have been performed worldwide. Studies have shown
that umbilical cord blood transplants from a family member, rather
than from a non-relative, have a significantly higher survival rate
than transplants from an unrelated donor.

   About ViaCord

   ViaCord allows expectant families the opportunity to preserve
their baby's umbilical cord blood for potential medical use by the
child or a related family member. The child's cord blood is collected
at the time of birth in the only FDA-approved cord blood collection
bag suitable for use in a sterile field. To date, ViaCord has
preserved over 130,000 newborn's umbilical cord blood. Additional

   Risks of Forward-Looking Statements

   This press release contains forward-looking statements regarding
the Company's expectations with respect to its ViaCord product
offering and timing for completion of the expansion of ViaCord
Processing Laboratory. These statements are based on management's
current expectations, and are subject to a number of risks and
uncertainties that could cause actual results to differ materially
from the Company's current expectations. For example, the Company's
expectations with respect to ViaCord may be negatively affected by the
impact of competition in the umbilical cord preservation industry, any
changes in market acceptance for family cord blood banking, any
slowing of growth of the family cord blood banking market, the impact
of any potential adverse outcome in pending patent infringement
litigation related to the cord blood preservation business, any
further impact of a third party's dispute with Mothers Work related to
the rights granted to the Company, including if a court were to vacate
the arbitrator's decision, and any unexpected material issues, delays
or failures in the collection, processing or storage of umbilical cord
blood by the Company or others in the industry. In addition, the
Company's expectations for the completion of the expansion may be
impacted by, among other things, unexpected delays in planned
construction work in the new space and in obtaining the requisite
permits and other approvals necessary to complete the construction
work and begin operations in the new space. For more detailed

forward-looking statements and the Company's other activities, see the
