Journal Club
November 05, 2020
The Journal Club with Dr. Oliver Medvedik returns on November 24th at noon EST and will be livestreamed on our Facebook page. The topic this month will be a new study in which researchers have again demonstrated that it is possible to reverse aspects of aging in the old cells of a living animal, not...
Old man with clock
March 24, 2020
Researchers at Stanford University have demonstrated they can rejuvenate human cells, making them more like young cells again, by rewinding an epigenetic aging clock. Epigenetic alterations and aging One of the hallmarks of aging is epigenetic alterations, which are the alterations to gene expression that our cells experience with age. They harm the fundamental functions...
Epigenetic wrapping
March 13, 2020
Today, we are going to take a look at the companies working on resetting cellular aging through a reprogramming approach that directly targets a core reason we age. Cellular reprogramming resets aging in cells As we age, our cells experience alterations to their epigenetic markers, and this, in turn, changes gene expression; this process is...

A recent open-access study published in Cell Stem Cell has shown that excluding Oct4 from the OSKM cocktail reduces epigenetic aberrations and off-target gene activation. Induced pluripotency and Yamanaka factors Pluripotent stem cells are cells that can become other cell types in the body; during natural development, they create differentiated stem cells and ultimately somatic...

A new study outlines multiple ways in which epiblast stem cells can be reprogrammed back into a fully pluripotent state, paving the way for a better understanding of epigenetics. The role of epigenetics Epigenetics are why our cells, which all have the same DNA, differ in function. A bone cell has the same genetics as...
