RANCHO CORDOVA, Calif. and LOS ANGELES, July 16, 2013 (GLOBE NEWSWIRE) --
ThermoGenesis Corp. (Nasdaq:KOOL) ("ThermoGenesis"), a leading supplier of
enabling technologies for the processing and storage of stem cells and other
biological tissues, and TotipotentRx Corporation ("TotiRx"), a privately held
California Corporation, which specializes in developing cell-based therapies
in the field of regenerative medicine and is the exclusive provider of
cell-based product and services to the Fortis Healthcare System, today
announced that they have entered into a definitive merger agreement. The
combined company is expected to become one of the first fully integrated
regenerative medicine companies, developing clinically validated, commercially
scalable, point-of-care cell therapies for major therapeutic markets,
including orthopedic, cardiovascular and neurologic indications.

Under terms of the agreement, ThermoGenesis will issue approximately
12,491,000 shares of its common stock to TotiRx which equates to a value of
approximately $18.6 million, based on ThermoGenesis' closing stock price of
$1.49 on July 15, 2013.The merger agreement has been unanimously approved by
the board of directors of each company. The transaction is expected to close
in the fourth quarter of calendar year 2013 and is subject to customary
closing conditions, certain financial conditions, regulatory approvals and
approval by the shareholders of ThermoGenesis and TotiRx. The combined company
is expected to be named Cesca Therapeutics ("Clinical Excellence in Stem Cell
Applications") and will continue to trade on NASDAQ under the ticker symbol
KOOL.

"This merger is transformative.By combining our cell-based device
technologies with TotiRx's clinically validated therapeutic protocols and cell
therapy kits for major therapeutic areas, we expect Cesca to be one of the
first fully integrated regenerative medicine companies," said Matthew T.
Plavan, Chief Executive Officer of ThermoGenesis."Our best-in-class products
will give healthcare providers the ability to consistently execute every step
of the cell therapy treatment process, at the patient's bedside, in less than
an hour and at a fraction of the cost of typical cell therapy models.This
merger also provides us with the important ability to rapidly and
cost-effectively commercialize these new cell therapies, by leveraging our
proprietary contract research organization and an exclusive, cell therapy
partnership with Fortis Healthcare System.Taken together with the foundation
of our cord blood device platform, method/design patent portfolio and existing
revenue streams, we believe this combination offers tremendous potential for
shareholder value creation."

TotiRx is a leading regenerative medicine development company that has eight
autologous cell therapies in various stages of clinical development targeting
areas of high unmet medical need, including osteoarthritis, avascular
necrosis, acute myocardial infarction and critical limb ischemia.TotiRx is
believed to be the world's only clinical research organization (CRO)
specializing solely in cellular therapeutic development services and utilizes
the breadth and depth of its expertise and service offerings, along with an
unmatched footprint in India, to navigate the complex and challenging cellular
therapy regulatory environment, improve efficiency, and deliver better
clinical trial outcomes.TotiRx also brings an established cord blood banking
business with a growing revenue stream and a high-value strategic partnership
with Fortis Healthcare, an esteemed chain of specialty hospitals networked
throughout India and across Asia.

"Regenerative medicine is one of the fastest growing areas of modern medicine
and is widely expected to become a major component of our future global
healthcare system," said Kenneth L. Harris, Chairman and Chief Executive
Officer of TotiRx."Key to being a leader in this market is the ability to
provide safe, effective, point-of-care therapy that works for the patient,
physician and hospital provider.The autologous cell therapy approach we
employ requires strict standards and control of collection, handling, and
redelivery to the body, but provides for significantly lower clinical and
regulatory risk, reducing cost and enhancing our speed to market.This merger
is the natural evolution for our existing strategic partnership with
ThermoGenesis, and the superior performance of their equipment, which we
currently use in both our clinical trial and cord blood businesses, has been
an integral component of our successful clinical trial work."

Strategic benefits of the merger include:

  *One of the First Integrated Regenerative Medicine Companies. Cesca
    Therapeutics will be one of the first companies to bring together
    cell-therapy-related devices, patented platform technologies, proprietary
    cell formulations and a cell-therapy-specific Clinical Research
    Organization.
    
  *One of the First to Provide Practical, Commercializable Cell Therapies.
    Cesca Therapeutics will offer safe and effective therapies backed by
    clinical evidence, including 10 clinical trials in osteoarthritis,
    avascular necrosis, cardiac and critical limb ischemia, among others,
    using patient- and regulator-friendly autologous cells and at the bedside,
    in a 60 minute protocol.
    
  *The Ability to Rapidly and Cost-Effectively Implement New Clinical
    Trials.Cesca Therapeutics will have the ability to rapidly initiate
    clinical development of new cell therapies at its U.S. FDA-registered CRO
    in India and generate high quality data at a fraction of the cost of
    clinical trials undertaken in the U.S. or Europe.
    
  *Positioned to Commercialize in Both Developed and Emerging
    Markets.Cesca's existing U.S. and Asian footprints uniquely position it
    to meet the needs of patients, hospitals, and physicians across the
    globe.This footprint allows flexibility to meet the variable market
    demands in service and price.
    
  *Significant Value Creation. As a combined company, Cesca Therapeutics
    should support a higher valuation than either company alone, with the
    potential to create additional, near and long-term shareholder value
    through growth in its base business and the development of new protocols
    in major therapeutic areas.

Mr. Plavan will serve as Chief Executive Officer of the new organization, and
Mr. Harris will serve as President. In addition to his role as President, Mr.
Harris will join the Board of Directors of the new company.

Tobin Chediak Coleman Grodin Law Corporation acted as legal counsel to
