Multipotent Stem Cell Proteins Support Rejuvenation While Inhibiting Skin Cancer

Histogen to present data at TERMIS AP Annual Conference in Shanghai.

We have also been studying the anti-cancer activity of these proteins, and have shown that, just as in the embryonic environment, they support normal tissue growth while resulting in the controlled death of cancer cells.

Histogen, Inc., a regenerative medicine company developing solutions based on the products of cells grown under simulated embryonic conditions, announced that the Company’s Chairman and CEO, Dr. Gail Naughton, will present today at the Tissue Engineering and Regenerative Medicine International Society (TERMIS) Asia Pacific Annual Meeting in Shanghai, China.

Through its proprietary technology process that simulates the conditions of the embryonic environment, Histogen is uniquely able to trigger the de-differentiation of skin cells into multipotent stem cells without genetic manipulation. The cells express key stem cell markers including Oct4, Sox2 and Nanog, and secrete a distinctive composition of growth factors and other proteins known to stimulate stem cells in the body, regenerate tissues, and promote scarless healing.

It is the soluble and insoluble compositions of multipotent proteins and growth factors resulting from this process that have been shown to both promote skin regeneration and induce controlled cell death in multiple skin cancers.

“The anti-aging and rejuvenation benefits of human multipotent stem cell proteins have been shown in several clinical studies, and have resulted in the material’s use as a thriving next-generation ingredient for skin care,” said Dr. Naughton. “In parallel, we have also been studying the anti-cancer activity of these proteins, and have shown that, just as in the embryonic environment, they support normal tissue growth while resulting in the controlled death of cancer cells.”

In vitro studies performed with Histogen’s material have shown reduction in Squamous Cell Carcinoma (SCC), Basal Cell Carcinoma, and Melanoma cell number through the mechanism of apoptosis, or controlled cell death, induced by the upregulation of Caspase in these cancer cells. In one in vivo model, melanoma load was reduced by up to 80% versus the control (p<0.05) by the addition of the insoluble multipotent stem cell proteins, and a dose response curve was seen. Similar inhibition was seen with SCC. In subcutaneous mouse experiments, tumor growth was inhibited by 70-90%.

"Human Multipotent Stem Cell Proteins Stimulate Skin Regeneration While Inducing Skin Cancer Cell Apotosis” will be presented by Dr. Naughton during the TERMIS AP Annual Meeting taking place October 23-26, 2013 in Shanghai. Further information and data on the ability of multipotent stem cell proteins to induce apoptosis in skin cancers can be found in the publication Journal of Cancer Therapy at http://file.scirp.org/Html/1-8901700_33923.htm.

About Histogen
Histogen is a regenerative medicine company developing solutions based upon the products of cells grown under proprietary conditions that mimic the embryonic environment, including low oxygen and suspension. Through this unique technology process, newborn cells are encouraged to naturally produce the vital proteins and growth factors from which the Company has developed its rich product portfolio. Histogen's lead product, Hair Stimulating Complex (HSC) has shown success in two Company-sponsored clinical trials as an injectable treatment for alopecia. In addition, the human multipotent cell conditioned media produced through Histogen's process can be found in skincare products including ReGenica, which is distributed by Suneva Medical in partnership with Obagi Medical Products.
