Autophagic State Prospectively Identifies Facultative Stem Cells in the Intestinal Epithelium
Researchers utilized in vivo labeling combined with ex vivo organoid formation assays to evaluate how cell age and autophagic state contributed to facultative stem cell activity within secretory lineages.
[Haematologica] 301 patients with a median age 60 years were enrolled. Of them, 287 and 274 patients collected ≥2 and ≥4×106 CD34+ cells/kg, respectively, with a median of 9.9×106 CD34+ cells/kg collected.
[EMBO Journal] The authors provide an in-depth review of the metabolic and epigenetic interplay regulating hematopoietic stem cell fate, and discuss the influence of metabolic stress stimuli, as well as alterations occurring during leukemic development.
