How Stem Cells Contribute to Aging and Age-Related Diseases
What challenges does aging pose to both individuals and society at large? What causes aging at the cellular and molecular level? Stem cell research is key to finding solutions that increase our healthspan and change how we think about aging. Robert A.J. Signer, Ph.D., shares what is on the horizon.

A Closer Look at…Aging
Can we leverage stem cells to help live longer, healthier lives? Robert A.J. Signer, Ph.D., and Shiri Gur-Cohen, Ph.D., examine the process of aging at the molecular and cellular level to show how stem cells may be the key to preventing age-related health problems.

Avoid shocking your hematopoietic stem cells to keep them young and growing
Expanding hematopoietic stem cells (HSCs) ex vivo has historically been a very challenging process. In this issue of Cell Stem Cell, Kruta et al., (2021) identify heat shock factor 1 (Hsf1) as a new target to maintain HSC fitness and protein homeostasis, not only in culture conditions but also upon aging.

BRCA1 gene is key for blood forming stem cells
Researchers have discovered that the BRCA1 gene is required for the survival of blood forming stem cells, which could explain why patients with BRCA1 mutations do not have an elevated risk for leukemia. The stem cells die before they have an opportunity to transform into a blood cancer.

Cellular Protein Production
The ability of our cells to operate properly is determined by the proteins that we produce. Proteins are not only critical building blocks in the production of new cells but also the enzymes that regulate most cellular processes, such as metabolic pathways.

Tailor Made Protein Synthesis for HSCs
Translation control is a prevalent form of gene expression regulation in developmental and stem cell biology. A recent paper by Signer et al. (2014) measures protein synthesis in the mouse hematopoietic compartment and reveals the importance of diminished protein production for maintaining hematopoietic stem cell function and restraining oncogenic potential.

Stem cell study opens door to undiscovered world of biology
For the first time, researchers have shown that an essential biological process known as protein synthesis can be studied in adult stem cells — something scientists have long struggled to accomplish. The groundbreaking findings from the Children’s Medical Center Research Institute at UT Southwestern (CRI) also demonstrate that the precise amount of protein produced by blood-forming stem cells is crucial to their function.
