Check out the LEAF interview with Synthetic Biology company CellAge who plan to use their technology to create aging biomarkers for the research community to use for free as well as new approaches to removing senescent cells.
CellAge are using synthetic biology to remove senescent cells that accumulate with age and contribute to disease. We took the time to interview them about their technology, treating age-related diseases and their plans for the future.
You can also check out their campaign on Lifespan.io:

Progress with treating osteoporosis.
A team of scientists at the Children’s Medical Center Research Institute at UT Southwestern (CRI) discovered a new bone-forming growth factor, Osteolectin (Clec11a), which reverses osteoporosis in mice and has implications for regenerative medicine.
Although Osteolectin is known to be made by certain bone marrow and bone cells, CRI researchers are the first to show Osteolectin promotes the formation of new bone from skeletal stem cells in the bone marrow. The study, published in eLife, also found that deletion of Osteolectin in mice causes accelerated bone loss during adulthood and symptoms of osteoporosis, such as reduced bone strength and delayed fracture healing.

An interesting but predictably hyped research study currently doing the rounds. Epigentic changes are one of the Hallmarks of Aging and this study reinforces their importance despite the usual media hype.
Graying hair, crow’s feet, an injury that’s taking longer to heal than when we were 20—faced with the unmistakable signs of aging, most of us have had a least one fantasy of turning back time. Now, scientists at the Salk Institute have found that intermittent expression of genes normally associated with an embryonic state can reverse the hallmarks of old age.
This approach, which not only prompted human skin cells in a dish to look and behave young again, also resulted in the rejuvenation of mice with a premature aging disease, countering signs of aging and increasing the animals’ lifespan by 30 percent. The early-stage work provides insight both into the cellular drivers of aging and possible therapeutic approaches for improving human health and longevity.

For the first time, scientists have used cellular reprogramming to reverse the ageing process in living animals, enabling mice with a form of premature ageing to live 30 percent longer than control animals.
The technique involves the use of induced pluripotent stem cells (iPSCs), which lets scientists reprogram skin cells to a base, embryonic-like state. From there, iPSCs can develop into other types of cells in the body – and now researchers have shown that reprogramming cells can also rejuvenate living creatures, in addition to winding back cells.
Getting old may not be inevitable — scientists have found a way to turn back the clock on human and animal cells, making them look and behave like younger versions of themselves.
The researchers also used the method to treat mice with a rare disease that causes them to age prematurely and die early, and found that the method increased the animals’ lifespan by 30 percent. And, when normal mice received the treatment, they appeared to be rejuvenated, with some of their cells healing faster than normal in response to injury.
The researchers said that their findings may help scientists better understand the process of aging. One day, it may be possible to use a similar approach to ward off age-related diseases in humans, and thus improve people’s health and increase their lifespan, they said.

Dr. Matthew O’Connor from the SENS Research Foundation gives a fascinating talk about this years successful results of the mitochondrial repair project (MitoSENS) and the potential for repairing age-related damage to the mitochondria that SENS proposes. 2017 could be an even better year for progress, please consider donating to the SRF Winter Fundraiser and help them make age-related disease a thing of the past.
Please take a few minutes to watch SENS Research Foundation’s Matthew O’Connor give a Google TechTalk during Google’s Giving Week campaign. The topic is his recently published article on our MitoSENS Research. If you enjoy this presentation and support our work please go to our website and donate today.

The team showed that a new form of gene therapy produced a remarkable rejuvenating effect in mice. After six weeks of treatment, the animals looked younger, had straighter spines and better cardiovascular health, healed quicker when injured, and lived 30% longer.
Juan Carlos Izpisua Belmonte, who led the work at the Salk Institute in La Jolla, California, said: “Our study shows that ageing may not have to proceed in one single direction. With careful modulation, ageing might be reversed.”
