“Yamanaka factors, a group of proteins that can reprogram differentiated (mature) cells into pluripotent stem cells, may be a therapeutically novel way to reverse cellular aging.”

“Bone tissue regeneration Researchers delivered a low-level laser treatment (808 nm) to implanted bone marrow stem cells to investigate the effects of LLLT on bone tissue regeneration in mice.”

“In one study where heart attack patients received stem cell therapy, the heart’s pumping efficiency improved by 8.5% after 4 months. Another study in which stem cells were injected into the patients’ hearts observed a 4.3% improvement in the heart’s pumping efficiency 6 months after their heart attack.”

“This video was produced mostly in response to some over-the-top spin the media placed on an otherwise interesting paper entitled: Variation in cancer risk among tissues can be explained by the number of stem cell divisions.”

“T cell production drops sharply after adolescence, followed by a sharp rise in the rate of thymic involution after age forty. New T cells arise from hematopoietic progenitor cells (i.e., blood stem cells) in the bone marrow and migrate to the thymus for maturation.”

“01:22:45 - Decreased sense of smell is a predictor of mild cognitive impairment and Alzheimer's disease. Study. 01:24:51 - Growth factors from the blood of young mice stimulates stem cell proliferation in the brain and muscles of older mice.”

“However, they appear to involve inhibiting key nutrient-sensing and inflammatory pathways and regulating multiple molecular, cellular, and metabolic pathways that promote protein homeostasis, genomic stability, oxidative stress resistance, and proper stem cell function.”

“Using Yamanaka transcription factors, geneticists are able to reverse the aging program and take an adult cell back to a stem cell. This method of cell rejuvenation may change the way we treat disease and injury in the future.”

“00:21:55 - Begin dialogue surrounding induced pluripotent stem cells (turning already differentiated cells, like skin cells, into stem cells). 00:27:00 - Figuring out the epigenetic program of cells, relevance for induced pluripotent stem cells.”

“The methylation patterns appear with age occur in polycomb group protein target regions that play a role in regulating stem cells. In this clip, Dr. Steve Horvath discusses whether epigenetic clocks play causal roles in aging.”
