Cell proliferation

Cell proliferation is the process that results in an increase of the number of cells, and is defined by the balance between cell divisions and cell loss through cell death or differentiation. Cell proliferation is increased in tumours.

    Increasing pancreatic β-cell proliferation in autoimmune type 1 diabetes (T1D) might restore β-cell mass but would be predicted to exacerbate islet inflammation. A study in Nature Metabolism, however, reports that boosting β-cell proliferation in mouse models of T1D is beneficial, preserving the immunological self-tolerance of islets through the induction of regulatory T cells.

    The metabolic phenotype of tumours is shaped by a complex interplay between cancer cells and their microenvironment. Two studies now show that aspartate acquisition is a metabolic limitation encountered by certain tumours in their native in vivo environment, and that overcoming this limitation is advantageous for tumour growth.

    The lung undergoes a striking repair process in response to severe injuries such as influenza infection. A study now demonstrates that associated stem/progenitor cells are heterogeneous in nature and comprise subpopulations dominated by hypoxia/Notch or Wnt signalling. Modulation of this heterogeneity in favour of functional repair may have therapeutic value.

    Vascular malformations result from improper blood vessel responses to molecular and mechanical signals. Two studies now show that endothelial cell migration and cell shape changes are perturbed in mutants lacking the TGFβ/BMP co-receptor endoglin, leading to arteriovenous shunts. Endoglin coordinates endothelial cell responses to ligand–receptor signalling and flow-mediated mechanical cues.
