Epigenetic effects of plasma concentrate

“We use data from a safety study (n = 18, mean age 74) to investigate whether human umbilical cord plasma concentrate (hereinafter Plasma Concentrate) injected weekly (1 ml intramuscular) into elderly human subjects over a 10-week period affects different biomarkers, including epigenetic age measures, standard clinical biomarkers of organ dysfunction, mitochondrial DNA copy number (mtDNA-CN), and leukocyte telomere length.

More than 20 clinical biomarkers were significantly and beneficially altered. Telomere length and mtDNA-CN were not significantly affected by treatment.

An increase in entropy means that the methylome becomes noisier. We found that entropy was significantly decreased after treatment. Decreased entropy may implicate rejuvenation of the epigenetic landscape after plasma concentrate treatments.

changes in methylation entropy

Treatment reduced DNA methylation-based GrimAge by an average of 0.82 years, suggesting a reduction in morbidity and mortality risk. By contrast, no significant results could be observed for epigenetic clocks that estimate chronological age.

Our study lends credence to the notion that there are youth-promoting factors in the secretome of umbilical cord plasma. This conclusion has also been reached by other researchers that have provided treatment with stem cells, which do not work by plasma dilution but primarily by providing humoral factors and changing the microenvironment of cells and tissues. While there may be youth-promoting microvesicles or humoral factors that are at work, we do not want to rule out the possibility that it is ‘young and undamaged’ albumin that leads to the improvements noted, especially in light of recent evidence for such a mechanism.

This first human epigenetic clock study of plasma concentrate treatments revealed age-reversal effects according to a well-established DNA methylation-based estimator of morbidity and mortality risk. Future placebo-controlled replication studies are warranted with a larger number of participants over a longer study period, which our laboratory has undertaken to pursue.”
