Bioidentical hormones are defined as man-made hormones that are very similar to the hormones produced by the human body. These are then used as treatment for men and women whose own hormones are low or out of balance. What are bioidentical hormones? Hormones are special chemicals made by parts of the body called glands. They […]
Human beings sleep for approximately one-third of their lifetime, but the endogenous mechanisms underlying sleep and its role in homeostasis remain to be fully elucidated. Sleep is important for plenty of reasons. Sleep impacts our hormones and hormone levels impact our sleep. Both too much and not enough time under the covers can influence hormones. […]
Stem cells are undifferentiated cells that are present in the embryonic, fetal, and adult stages of life and give rise to differentiated cells that are the building blocks of tissue and organs. In the postnatal and adult stages of life, tissue-specific stem cells are found in differentiated organs and are key in repairing any type […]
The US Food and Drug Administration (FDA) has authority to regulate regenerative medicine products, including stem cell products and exosome products. A common question that we hear is, “are stem cell treatments approved by the FDA?” The answer is that there are some treatments that are fully approved, but many are still being studied and […]
Stem cells are the body’s raw materials, cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells. These daughter cells either become new stem cells (self-renewal) or become specialized cells (differentiation) with a more […]
Regular physical activity has a wide range of health benefits. These include a reduced risk of cardiovascular disease, type 2 diabetes, various mental health conditions, and dementia. Studies show that people who are physically active are less likely to experience a decline in their mental function and have a lowered risk of developing Alzheimer’s disease. […]
Cholesterol is an essential lipid for maintaining cellular homeostasis. Besides being a precursor for steroid hormones, and being an essential component of plasma membranes, it is also enriched in lipid rafts and plays a key role in intracellular signal transduction. Cholesterol is primarily synthesized in the liver and transported to cells around the body through […]
Immune system T cells have been reprogrammed by a group of researchers from the Georgetown Lombardi Comprehensive Cancer Center into regenerative stem cell-like memory cells (TSCM) that are long-lived, highly active “super immune cells” with strong antitumor activity. Cancer immunotherapy, also known as immuno-oncology, is a form of cancer treatment that uses the power of […]
Most developing and adult tissues are hierarchically organized such that tissue growth and maintenance are driven by the production of lineage-committed cells from populations of tissue-resident stem and progenitor cells. Stem cells in adult tissues are typically found in a quiescent or reversible G0 state and must re-enter the cell cycle and divide to promote […]
Microbes that live in our gut don’t just digest food. They also have far-reaching effects on the immune system. A new study shows that a particular gut microbe can prevent severe flu infections in mice, likely by breaking down naturally occurring compounds, called flavonoids, commonly found in foods such as black tea, red wine, blueberries […]
