This Episode's Stem Cell Roundup:

• Hair Thinning in Obesity – Researchers found that obesity-induced stress depletes hair follicle stem cells in mice.
• Tracking Keratinocyte Stem Cells – Scientists used deep learning to track the motion of individual keratinocytes and keratinocyte stem cells, allowing them to identify the stem cells in a mixed population and study how culture conditions affect dynamics.
• Flipping a Switch in Heart Failure – Researchers identified a transcriptional switch that controls the activation of fibroblasts, and could be used to prevent fibrosis in the heart and other organs.
• Mapping Mouse Brain Development – Scientists used single cell sequencing to generate a comprehensive atlas of the developing mouse neocortex.
