Figure 2. A model of in vivo adipogenesis.
A schematic representation of the adipocyte cellular lineage is shown. The defined lineage, cell surface, and transcriptional markers for each cell type are shown below each listed cell type. Positive markers are shown in blue while negative markers are shown in gold. The question marks highlight that it is currently unclear if the adipocyte progenitor population contains self-renewing adipocyte stem cells or if the adipocyte progenitors are repopulated by another, unidentified population of adipocyte stem cells in adults.
