Chinese Licorice
Researchers publishing in Aging have reported that licochalcone A (LA), a flavonoid that originates from Chinese licorice, restores human adipose-derived stem cells (hADSCs) in cell culture. Reported positive effects Previous research on Licochalcone A has discovered that it has anti-inflammatory and anti-tumor effects [1], reduces obesity in mice [2], and protects against liver failure through...
Dividing stem cells
Researchers have found that hematopoietic stem cells lose function as they grow larger and that rapamycin can alleviate this effect [1]. When cells become obese When it comes to cells, size matters, with stem cells being on the smaller side [2]. Scientists have suspected for quite some time that this wasn’t a coincidence, but the relationship...

In a study published in Aging, researchers have found that younger hematopoietic cells can restore older hematopoietic cells through microvesicles, which are facilitators of intercellular communication. Why we Age: Altered Intercellular CommunicationAltered intercellular communication, as described in the Hallmarks of Aging, is the change in signals between cells that can lead to some of the...
Broken DNA
A review published in Frontiers in Cell and Developmental Biology has explained how DNA damage and its accompanying immune response lead to changes in the microenvironment of stem cells, causing a decline in their function. Why we Age: Stem Cell ExhaustionStem cell exhaustion is the age-related deficiency of stem cells. This particular hallmark is directly...
Small meal
A review published in The Malaysian Journal of Medical Sciences has outlined what effects caloric restriction (CR) has on the development and differentiation of stem cells. Stem cells and their exhaustion The reviewers began by discussing stem cell exhaustion, a hallmark of aging and a common concern of aging research that we have covered extensively....
DNA Blood Cells
Researchers publishing in Cell Stem Cell have identified a protein that helps hematopoietic stem cells (HSCs) both in ex vivo cultures and in aging tissues. The problem with culturing cells Why we Age: Loss of ProteostasisThe loss of proteostasis is the failure of the protein building machinery of the cell and the accumulation of misfolded...
