Regenerative Drug Restores Bone In Preclinical Study

Bone loss is a part of aging that affects the quality of life and mobility of many older adults, yet there are limited regenerative therapies to improve their health and well-being. Now, a study led by Lankenau Institute of Medical Research (LIMR) scientist Ellen Heber-Katz, Ph.D., has demonstrated that an experimental regenerative medicine developed in her lab can restore bone in animals. This Preclinical studies Focus on the periodontal disease model, which causes the gums and bone loss cause tooth loss. In older adults, the disease not only causes pain and discomfort, but is the most common cause of tooth loss, affecting 30-60% of adults.However, the findings suggest that the experimental time-releasedrug , known as 1,4-DPCA, completely repairs diseased gums and the surrounding jawbone, completely preventing tooth loss.Findings were published in November by the Heber-Katz team at LIMR, part of Main Line HealthFrontiers in Dental Medicine

. “The development of this experimental drug represents one of the most cutting-edge research directions LIMR is driving in the 21st century,” said Institute President and CEO George Prendergast. “Beyond the uncertainty surrounding stem cell therapy, this study provides the first preclinical proof of concept for an off-the-shelf drug that can significantly improve an individual’s healthspan by regenerating bone. It also presents for the first time this Potential Antiaging Uses medical treatement on how to broaden how to use it to guide the perfect recover

by the body. ” Periodontal treatment is a branch of Heber-Katz researchregenerative medicine

, she took a startling new direction in the mid-1990s. That’s when she discovered a laboratory mouse strain that disproved the scientific assumption that only amphibians such as starfish and salamanders can heal wounds in a way that it appears the injury never occurred. “The results of this study were as robust as we expected,” said Heber-Katz, the Daniel B. and Florence E. Green Research Chair in Regenerative Medicine. “The repair of a lot of lost bone and tissue has been done. I’m optimistic that this drug will move forward and eventually be used in prophylaxis tooth loss in patients withperiodontal disease

— one of the many ways we think it might be useful. ”

The drug 1,4-DPCA works by inhibiting a molecule that prevents the production of a master molecule called hypoxia-inducible factor-1 (HIF-1a), a key component of the body’s healing response. By temporarily elevating HIF-1a, the drug shifts the metabolic state of the tissue to one for early fetal development, in this case allowing for perfect healing without scarring. Heber-Katz came to LIMR, an organization with expertise in early drug discovery and development, to advance research on compounds such as 1,4-DPCA to activate HIF-1a.The works are based on her earlier biological research

On how tissue regeneration is stimulated during the body’s healing response to injury.

Heber-Katz’s colleagues include LIMR faculty members Azamat Aslanukov, MD, and Kamila Bedelbaeva, MD. Additional collaborating researchers are from the Penn School of Dental Medicine and the University of California, Berkeley.

• Heber-Katz has two related patent-pending products nearing human testing: Topical or injectable hydrogel medications made from 1,4-DPCA or related compounds. These formulations are used to promote skin healing or restore skin integrity, including tissue damaged by natural aging.chronic wounds that don’t usually heal
