Vibrational phenomics decoding of the stem cell stepwise aging process at single-cell resolution.

Published in: Chemical communications (Cambridge, England) (2024)

We introduce vibrational spectroscopy to quantitatively measure the phenotypic heterogeneity of senescent stem cells in the aging process at the single cell level. Using an aging model of serially passaged human mesenchymal stem cells (MSCs), we characterized the phenotypic changes of MSCs during different aged stages and discovered a stepwise aging process with several distinct subtypes.
