A connection between senescence and stem cells caused by a breast cancer-initiating protein


High levels of the protein RANK triggers controlled cell death and aging which can delay the formation of tumors in the early stages of cancer: “Located in the membrane of cells, when it binds to its partner RANKL, it sends signals that stimulate the development of the mammary gland. When these proteins do not work properly, breast cells begin to divide and multiply uncontrollably, resulting in breast cancer.”


Mesenchymal Stem Cells Show Potential to Treat NTM Lung Infections


“Treatment with human mesenchymal stem cells (MSCs) effectively lessened hard-to-treat non-tuberculous mycobacteria (NTM) lung infection, and its associated weight loss, in a new mouse model susceptible to these infections, an early study reported.”


AI tracks cell movements in stem cell colonies


Using computer algorithms, scientists were able to track individual cells as they grew in colonies and record their movement precisely. “This technique gives us a much more comprehensive view of how cells behave, how they work cooperatively, and how they come together in physical space to form complex organs,” said co-author Todd McDevitt.


Scientists identify small-molecule cocktail to improve stem cell use in research and disease treatments


Stem cells are hypothetically able to replicate forever, at least the pluripotent ones, and are intended to serve as a source for specialized cells. But their growth is hampered by the stress of growing in cell culture dishes and induced environments. However with use of a new cocktail it can successfully diminish negative impacts of artificial environments on cells intended to be used for medicinal purposes.
