Acute myocardial infarction (AMI) and the heart failure that often follows, are major causes of death and disability worldwide. As such, new therapies are required to limit myocardial infarct (MI) size, prevent adverse left ventricular (LV) remodeling, and reduce the onset of heart failure following AMI. The inflammatory response to AMI, plays a critical role in determining MI size, and a persistent pro-inflammatory reaction can contribute to adverse post-MI LV remodeling, making inflammation an important therapeutic target for improving outcomes following AMI.

Over the past decade, microRNA-142 (miR-142) is emerging as a major regulator of cell fate decision in the hematopoietic system. However, miR-142 is expressed in many other tissues, and recent evidence suggests that it may play a more pleiotropic role during embryonic development. In addition, miR-142 has been shown to play important functions in disease.

Article Synopsis
  • Traumatic brain injuries and degenerative neurological disorders lead to loss of brain cells, and using stem cells, particularly adipose-derived stem cells (ADSCs), offers a potential treatment to restore brain function.
  • The study focused on the effects of human ADSCs on the regeneration of the rat sciatic nerve after a traumatic injury, finding that rats treated with ADSCs had less cellular loss and less formation of neuromas compared to untreated controls.
  • The results indicated that hADSCs not only support neuron survival but also enhance axonal repair and peripheral nerve regeneration, as shown by improved myelination and reduced inflammation two months post-injury.

Alveolar type-II cells (ATII cells) are lung progenitor cells responsible for regeneration of alveolar epithelium during homeostatic turnover and in response to injury. Characterization of ATII cells will have a profound impact on our understanding and treatment of lung disease. The identification of novel ATII cell-surface proteins can be used for sorting and enrichment of these cells for further characterization.
