“Study. 00:39:20 - The counter-intuitive phenomenon whereby older males accumulate a subset of germ-line stem cells that produce sperm with longer telomeres that are actually heritable and get passed on to their offspring. Study.”

“This shrinking of pathological markers activates stem cells, leading to the proliferation of oligodendrocyte precursors (myelin producing cells) and, ultimately, remyelination. Upon refeed, immune cells return naïve or at lower levels than controls -- in other words, with reduced autoimmunity.”

“Metabolic biotransformation As non-nutrients, isothiocyanates such as sulforaphane experience vigorous biotransformation in the human gut and demonstrate a wide range of bioavailability. The compounds passively diffuse into gut epithelial cells, where cytochrome P450 enzymes may oxidize them to reactive intermediate compounds.”

“Interrupted cellular reprogramming capitalizes on residual epigenetic memory and requires the presence of Yamanaka factors, a group of proteins that can reprogram differentiated (mature) cells into pluripotent stem cells.”

“Anti-aging effects Berberine exerts anti-aging effects in cell culture, insect, and rodent studies. Cell culture studies demonstrate that berberine attenuates cellular senescence, a process of deterioration that occurs with age.”

“Liver When researchers used liver organoids derived from human stem cells to study microplastic exposure, they found that even low environmental levels of polystyrene microplastics increased the expression of certain genes like HNF4A and CYP2E1.”

“But some of the primary contributors to whether a woman continues to breastfeed stem from more personal factors, ranging from sore nipples and plugged ducts to lack of family support and concerns about physical image and sexual intimacy.”

“Findings from a recent study in mice suggest that acute stress depletes melanocyte stem cell populations to promote the graying of hair. Melanocyte stem cells are undifferentiated cells found in the region of hair associated with growth.”

“Preclinical evidence indicates that dasatinib + quercetin selectively clears senescent cells, leading to improvements in various age-related diseases. A study of cells in culture found that dasatinib + quercetin decreased the number of senescent cells without affecting healthy cells.”
