In this study, we tested a stem cell secretome product, which contains extracellular vesicles and growth factors, cytoskeletal remodeling factors, and immunomodulatory factors. We examined the effects of 4 weeks of 2×/week unilateral intramuscular secretome injections (quadriceps) in ambulatory aged male C57BL/6 mice (22-24 months) compared to saline-injected aged-matched controls.
Secretome delivery substantially increased whole-body lean mass and decreased fat mass, corresponding to higher myofiber cross-sectional area and smaller adipocyte size, respectively. Secretome-treated mice also had greater whole-bod...

This study also reports the expansion of satellite cells in human muscle with CR. This finding is critical to suggest translational relevance to the rodent data observed for more than a decade. Moreover, the increased expression of the plasminogen receptor Plg-RKT observed on human satellite cells during CR provided additional support for the theory that our rodent model is relevant to human biology.

Human Exosomes Harvested from Stem Cells in Urine Produce Rejuvenation in Mice
In this study, we further analyzed these data and found that a class of USC-EVs-enriched proteins have been previously shown to possess anti-aging function, such as tissue inhibitor of metalloproteinases 1 (TIMP1), plasminogen activator urokinase (PLAU), insulin-like growth factor binding protein 5, senescence marker protein-30, and connective tissue growth factor. Thus, we hypothesized that USC-EVs might be capable of rejuvenating old organs from aging via transferring of anti-aging proteins.
Here, we tested the effects of USC-EVs on cellular senescence in vitro and on the aging-related phenotypes in different orga...

A Lengthy View of Everything that is Wrong with the Drug Development Industry
The primary problems with drug development are self-evident from the data. Firstly the process of drug development has become enormously more expensive over the past seventy years, a period in in which rapid technological progress has diminished the cost and effort required for any task in pharmacology and biotechnology by orders of magnitude. Secondly, the pace at which useful new medicines emerge in the clinic has diminished considerably, over the same period of technological progress in which the bounds of the possible have opened up enormously. The article I'll point out today is well worth reading, a lengthy treatment...

Request for Startups in the Rejuvenation Biotechnology Space, 2024 Edition
Investors focused on funding biotechnology startups tend to exhibit herd behavior, much like investors everywhere these days. Funding is primarily deployed towards fads and popular trends, not necessarily towards what makes the most sense, even if sometimes the sensible manages to align with the popular. These days that means drug discovery platforms with a strong computational component and partial epigenetic reprogramming. But even in this environment, the path to true success is to work on important projects that few other people are touching. Be the champion for a potential solution to a tough, high-value, comparativel...

Increased Dietary Leucine Activates mTOR Signaling in Macrophages, Accelerating Atherosclerosis
https://www.fightaging.org/archives/2024/02/increased-dietary-leucine-activates-mtor-signaling-in-macrophages-accelerating-atherosclerosis/
Leucine is an essential amino acid, only obtained from the diet rather than synthesized by our cells. Leucine supplementation has been proposed as a way to slow the loss of muscle mass with age, as leucine processing becomes dysregulated with aging in a way...

Telomere Length as a Target for Therapy
Average telomere length in a tissue is some reflection of (a) stem cell activity and (b) pace of cell division. Telomeres, repeated DNA sequences at the ends of chromosomes, lose some of their length with each cell division, and cells self-destruct or become senescent when telomeres become too short. This limits the ability of somatic cells to replicate, reducing the odds that a given cell will mutate to become cancerous by imposing a limit on cell activity and cell life span, enforcing turnover of cells in tissues. Stem cells, in comparison, are a small, well protected, privileged set of cell populations that use telomera...

To the degree that senescent cells in a tissue exhibit distinctive surface features, one can deploy technologies such as chimeric antigen receptor T cells to selectively destroy them. T cells will destroy whatever cell binds to the chimeric antigen receptor they are equipped w...

Making a Mouse that Exhibits Human Telomere Dynamics
Telomerase acts to extend telomeres, the repeated DNA sequences at the ends of chromosomes. With every cell division, some of the telomere repeats are lost. Cells with critically short telomeres become senescent or undergo programmed cell death, having reached the Hayflick limit on replication. Some cells employ telomerase to adjust the countdown of telomere length. In humans, only stem cells use telomerase. In other species, such as mice, telomerase is much more widely expressed. There has been some interest in the research community in upregulation of telomerase as a way to improve stem cell and tissue function in old ag...

Exosomes as a Treatment for Skin Aging
Much of the communication that takes place between cells takes the form of secretion and uptake of extracellular vesicles, small membrane-wrapped packages of diverse molecules. Vesicles are currently categorized by size, for lack of a better taxonomy, and exosomes are one of the better studied size classes. It appears to be the case that much of the benefit of first generation stem cell therapies is produced by the signaling generated by transplanted cells, and thus the research community has started to focus on the logistically easier approach of harvesting and using extracellular vesicles rather than transplanting the ce...

Claims Software Can Ease Manual Processes Related to Treating Medical Tourists from Outside the U.S.
The following is a guest article by Rob Stuart, Founder and President at Claim.MD
Medical tourism is big business for leading hospitals and health centers around the world. In the United States, the overwhelming perception is that American patients seek treatment in Mexico, Turkey, Singapore, and other places to save money over what they’d pay for the same treatments. But the U.S. has been named the top worldwide medical tourism destination.
Because many people don’t proclaim themselves as medical tourists on travel documents, reliable statistics on the prevalence of medical travel are scarce. However, a 2017 survey li...
