Histogen CEO Presents Extracellular Matrix Data for the First Time at MD&M West

Embryonic extracellular matrix contains unique composition of proteins for rapid cell proliferation and healing without scars

SAN DIEGO, January 31, 2008 - Gail Naughton, CEO of Histogen, Inc., a regenerative medicine company developing solutions based on the products of newborn fibroblasts, will present data on the company's unique embryonic extracellular matrix (ECM) today at the MD&M West Conference in Anaheim, Calif.

Through the company's proprietary bioreactor technology, Histogen is uniquely capable of simulating the embryonic environment, including hypoxic conditions of 1-5% oxygen, creating a human extracellular matrix with a wide distribution of embryonic proteins unmatched by adult ECM.

"Histogen's human extracellular matrix contains a variety of proteins found only in the embryonic environment," said Dr. Robert Kellar, VP of Research and Development at Histogen. "Our human ECM provides the benefits of a natural biologic for surface modification and tissue regeneration, without the problems of allergic responses and possible viral transmission associated with porcine and bovine derived materials."

Under these hypoxic culture conditions, over 5,000 genes are differentially expressed as compared to cells grown under traditional tissue culture conditions. These distinct genes may be responsible for encouraging increased wound healing and regeneration.

"It is well known that operations performed in the prenatal environment will not leave scars present at birth," said Dr. Gail Naughton, CEO of Histogen. "To be able to replicate this rapid, scarless healing in adult patients would mean countless benefits in the areas of plastic and general surgery. The regenerative capabilities of the embryonic-like matrix also support its use as a coating for medical devices and as patches for hernia and soft tissue repair."

Histogen CEO Speaks on Bringing Tissue Engineered Products from Lab to Market at MD&M Conference

November 15, 2007 - Gail Naughton, CEO of Histogen, Inc., a regenerative medicine company developing solutions based on the products of newborn fibroblasts, addressed attendees at the annual Medical Design & Manufacturing (MD&M) Conference, Minneapolis this October. Naughton utilized past experiences in bringing four cell-based products from concept to market, while at Advanced Tissue Sciences, to present the challenges and best practices for the development and approval of human cell-based regenerative medicine products.

"Cell based regenerative medicine products offer great potential to address countless of patient unmet needs. The high cost of manufacturing these products, long clinical timelines, and challenges with reimbursement have tremendously hurt product development and investment in this important field," said Naughton. "Developing a robust product pipeline based on one cell type and one manufacturing system is key, and can reduce the cost of developing a new product indication by 75%. It is also critical to have products with short and midterm markets and those where reimbursement challenges do not exist. Histogen's business plan and products directly address each of these key issues."

In addition to presenting at MD&M Minneapolis, which took place on October 16-17, 2007, Naughton will revisit the topic at MD&M West in January 2008.

Gail Naughton has spent more than 15 years extensively researching the tissue engineering process, and holds more than 90 patents in the field. During her time with Advanced Tissue Sciences, Naughton raised $350 million from the public market and corporate partnerships, and oversaw the design and development of the world's first upscale manufacturing facility for tissue engineered products.
