Woburn, MA, Feb. 13, 2017 – CellMosaic announces that it has formed a separate division to support development and commercialization of its proprietary AqueaTether™ (AqT™) technologies. The new entity will control and manage the technology and intellectual property of AqT™ to better service its partners.

The driving motivation for the new division is to simplify the intellectual property and licensing for the AqT™ technology without interfering with CellMosaic’s existing service business and CellMosaic’s other intellectual property, but the spin out from its parent company, CellMosaic, Inc., also establishes a single business focus for developing AqT™ opportunities in life science applications. The separation of AqT™ into a separate division will allow CellMosaic clients to continue to engage in traditional and custom bioconjugation services, and also allow independent, proprietary AqT™ development programs to be more flexible for our partners.

“The structuring of AqueaTether™ Therapeutics as a separate division out of CellMosaic’s core service business will help both CellMosaic and AqT™ to best meet the needs of our clients and our development partners”, said Dr. Yumei Huang, founder and CEO of CellMosaic. “We are also very pleased to announce the appointment Walter Lunsmann to lead AqT™ Therapeutics. Walter brings a great range of experience in drug delivery and development, and we’re very enthusiastic to have him help expand the impact of the AqT™ technology to the life sciences.” Dr. Yumei Huang will serve as the Chief Scientific Officer of AqueaTether™ Therapeutics.
