These results represent a potential treatment for melanoma and other solid tumors that works through multiple channels to eliminate cancer cells, but is not toxic to the body’s healthy cells
Atlanta, GA (PRWEB) May 06, 2015
Histogen, Inc., a regenerative medicine company developing solutions based on the products of cells grown under simulated embryonic conditions, will present new research on its 105F immunomodulatory treatment candidate for melanoma during the 2015 Society of Investigative Dermatology (SID) Annual Meeting, taking place May 6-9, 2015 in Atlanta, GA.
Histogen has previously shown that hypoxia-induced multipotent cells produce a soluble material with anti-oncologic properties, with potential benefit in the treatment of a wide range of cancers. Studies to characterize the active components of the material have identified a low molecular weight fraction (105F) which directly induces apoptosis, or controlled cell death, in 21 human cancer cell lines. In its latest research, Histogen sought to further examine the mechanism of action of 105F in melanoma through in vitro and in vivo studies.
After treatment with 105F, melanoma cells were shown to release Interleukin 6 (IL-6) and TNF a, pro-inflammatory cytokines acting as signals to the immune system. This induction of an immune “flare” in combination with tumor cell apoptosis could be critically important in recruiting immune cells to the tumor for cytotoxic attack.
“We were excited to see the dual activity of 105F, both directly inducing cancer cell death and activating an anti-tumorigenic immune response to reduce metastatic disease,” said Dr. Gail Naughton, CEO and Chairman of the Board of Histogen. “These results represent a potential treatment for melanoma and other solid tumors that works through multiple channels to eliminate cancer cells, but is not toxic to the body’s healthy cells.”
An in vivo model of lung metastasis in C57Bl/6 mice further showed the efficacy of 105F in the treatment of melanoma. Daily intravenous injections of 105F over 14 days resulted in a significant (p=0.0049) reduction in lesions and marked immune cell infiltration as compared to controls.
Dr. Naughton will present “105F is a novel immunoadaptive treatment candidate for melanoma that induces apoptosis and the secretion of pro-inflammatory IL-6” at the 2015 SID Annual Meeting in Atlanta beginning May 6, 2015. Following the event, the presentation will be available upon request.
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 technology focuses on stimulating a patient's own stem cells by delivering a proprietary complex of multipotent human proteins that have been shown to support stem cell growth and differentiation.
