Transhumanism — advocates strongly for humans to develop and make widely available sophisticated technologies that enhance human physiology and intellect greatly. In layman’s terms, transhumanists would like for human beings to become cyborgs; cybernetic organisms.

As such, transhumanist concepts feature greatly in science fiction. Cyborgs are commonly seen in all forms of science fiction media…

This story is part of a series on the current progression in Regenerative Medicine. In 1999, I defined regenerative medicine as the collection of interventions that restore to normal function tissues and organs that have been damaged by disease, injured by trauma, or worn by time. I include a full spectrum of chemical, gene, and protein-based medicines, cell-based therapies, and biomechanical interventions that achieve that goal.

As part of a trio of stories on advances in stem cell gene therapy, this piece discusses how to alter blood stem cells using mRNA technology. Previous installments describe how the same platform could reinvent how we prepare patients for bone marrow transplants and correct pathogenic DNA.

At present, the only way to cure genetic blood disorders such as sickle cell anemia and thalassemia is to reset the immune system with a stem cell transplantation. Only a fraction of patients elects this procedure, as the process is fraught with significant risks, including toxicity and transplant rejection. A preclinical study published in Science explores a solution that may be less toxic yet equally effective: mRNA technology. The cell culture and mouse model experiments offer a compelling avenue for future research to enhance or replace current stem cell transplantations altogether.

In a groundbreaking endeavor, researchers at the University of Rochester have successfully transferred a longevity gene from naked mole rats to mice, resulting in improved health and an extension of the mouse’s lifespan.

Naked mole rats, known for their long lifespans and exceptional resistance to age-related diseases, have long captured the attention of the scientific community. By introducing a specific gene responsible for enhanced cellular repair and protection into mice, the Rochester researchers have opened exciting possibilities for unlocking the secrets of aging and extending human lifespan.

“Our study provides a proof of principle that unique longevity mechanisms that evolved in long-lived mammalian species can be exported to improve the lifespans of other mammals,” says Vera Gorbunova, the Doris Johns Cherry Professor of biology and medicine at Rochester. Gorbunova, along with Andrei Seluanov, a professor of biology, and their colleagues, report in a study published in Nature that they successfully transferred a gene responsible for making high molecular weight hyaluronic acid (HMW-HA) from a naked mole rat to mice. This led to improved health and an approximate 4.4 percent increase in median lifespan for the mice.

I recently just read a post about the “University of Queensland researchers discovered that the protein ATFS-1 aids in cell longevity by balancing new mitochondria creation and repair.”

It reminded me of this:

I recently came across an article about nurturing your mitochondria. One of the benefits to doing this relates to aging — apparently looking after your mitochondria will help counteract much of what we associate with aging, such as declining energy levels.

Peter Diamandis is best known as the founder of the XPrize Foundation, which offers big cash prizes as an incentive for tech solutions to big problems. The entrepreneur and investor is also co-founder of the Singularity University, a Silicon Valley-based nonprofit offering education in futurology. His new book, The Future Is Faster Than You Think, argues that the already rapid pace of technological innovation is about to get a whole lot quicker.

Do you think people are worried about where technology is going to take us? I can palpably feel how fast things are changing and that the rate of change is accelerating, and I have picked up a growing amount of fear coming from people who don’t understand where the world is going. And that is not good when you’re trying to solve problems. This book is about giving people a roadmap for where things are going over the next decade so they have less fear and more anticipation. Because, yes, in the next 10 years, we’re going to reinvent every industry on this planet, but the change is one that is for the benefit of masses, whether it’s in longevity or food or banking.

“Microglia exhibit both maladaptive and adaptive roles in the pathogenesis of neurodegenerative diseases and have emerged as a therapeutic target for central nervous system (CNS) disorders, including those affecting the retina,” wrote the researchers. “Replacing maladaptive microglia, such as those impacted by aging or over-activation, with exogenous microglia that enable adaptive functions has been proposed as a potential therapeutic strategy for neurodegenerative diseases. To investigate the potential of microglial cell replacement as a strategy for retinal diseases, we first employed an efficient protocol to generate a significant quantity of human-induced pluripotent stem cells (hiPSC)-derived microglia.”

“Our understanding of microglia function comes predominantly from rodent studies due to the difficulty of sourcing human tissue and isolating the microglia from these tissues. But there are genetic and functional differences between microglia in mice and humans, so these studies may not accurately represent many human conditions,” explained lead author Wenxin Ma, a PhD, biologist at the Retinal Neurophysiology Section, National Eye Institute, National Institutes of Health.

“To address this concern, researchers have been growing human microglia from human stem cells. We wanted to take this a step further and see if we could transplant human microglia into the mouse retina, to serve as a platform for screening therapeutic drugs as well as explore the potential of microglia transplantation as a therapy itself,” added senior author Wai Wong, vice president of retinal disease, Janssen Research and Development.

Step forward platelet factor 4 (PF4): this substance in the blood has been linked to the mental boost we get from exercise, the benefits of blood transfusions, and a protein associated with longevity, in three separate studies.

All three processes promote cognitive enhancement, meaning PF4 is something of a superpowered blood factor. The research was carried out by two teams from the University of California San Francisco (UCSF) in the US and the University of Queensland in Australia.

Platelets are cell fragments that play a critical role in the clotting process. Aside from serving as physical plugs that staunch bleeding, these small, non-nucleated chunks of bone marrow cell contain granules that release chemicals to promote aggregation.

Researchers at The University of Queensland have found an anti-aging function in a protein deep within human cells.

Associate Professor Steven Zuryn and Dr. Michael Dai at the Queensland Brain Institute have discovered that a protein called ATSF-1 controls a fine balance between the creation of new mitochondria and the repair of damaged mitochondria.
