AI Article Synopsis

  • Stem cells possess abilities to self-renew, replicate, and differentiate into various cell types, while progenitor cells are either undifferentiated or specialized stem cells with significant roles in regenerative medicine.
  • Stem and progenitor cells secrete important factors like cytokines and exosomes, but challenges such as limited source materials and low success rates in therapies highlight the need for improved methods.
  • Low-intensity pulsed ultrasound (LIPUS) is an emerging technology that can influence biological functions, potentially enhancing stem/progenitor cell activities and promoting advancements in regenerative medicine through biochemical changes.

Article Abstract

Stem cells have self-renewal, replication, and multidirectional differentiation potential, while progenitor cells are undifferentiated, pluripotent or specialized stem cells. Stem/progenitor cells secrete various factors, such as cytokines, exosomes, non-coding RNAs, and proteins, and have a wide range of applications in regenerative medicine. However, therapies based on stem cells and their secreted exosomes present limitations, such as insufficient source materials, mature differentiation, and low transplantation success rates, and methods addressing these problems are urgently required. Ultrasound is gaining increasing attention as an emerging technology. Low-intensity pulsed ultrasound (LIPUS) has mechanical, thermal, and cavitation effects and produces vibrational stimuli that can lead to a series of biochemical changes in organs, tissues, and cells, such as the release of extracellular bodies, cytokines, and other signals. These changes can alter the cellular microenvironment and affect biological behaviors, such as cell differentiation and proliferation. Here, we discuss the effects of LIPUS on the biological functions of stem/progenitor cells, exosomes, and non-coding RNAs, alterations involved in related pathways, various emerging applications, and future perspectives. We review the roles and mechanisms of LIPUS in stem/progenitor cells and exosomes with the aim of providing a deeper understanding of LIPUS and promoting research and development in this field.

Fatty acid oxidation is of uncertain importance in most stem cells. We show by C-palmitate tracing and metabolomic analysis that hematopoietic stem/progenitor cells (HSPCs) engage in long-chain fatty acid oxidation that depends upon carnitine palmitoyltransferase 1a (CPT1a) and hydroxyacyl-CoA dehydrogenase (HADHA) enzymes. CPT1a or HADHA deficiency had little or no effect on HSPCs or hematopoiesis in young adult mice.

Adult hippocampal neurogenesis (AHN), the process of generating new neurons from adult neural stem/progenitor cells (NSPCs), is crucial for cognitive functions and is influenced by numerous factors, including metabolic processes. Pyruvate kinase M2 (PKM2), a key rate-limiting enzyme in glycolysis, catalyzes the production of pyruvate, which undergoes either oxidative phosphorylation or anaerobic oxidation. We observed that PKM2 is highly expressed in NSPCs, but its significance remains unclear for AHN and cognition.

Background: MicroRNAs (miRNAs) have emerged as an essential regulator of the cell fate commitment of neural stem/progenitor cells (NPCs), although the impacts of certain miRNAs on NPCs remain vague. The aim of this study is to investigate the regulatory effects of on the cell fate commitment of NPCs.

Methods: We investigated the impact of on the proliferation and differentiation capacities of primary NPCs by manipulating the expression of using specific mimics and inhibitors.

Background: With the increasing risk of nuclear exposure, more attention has been paid to the prevention and treatment of acute radiation syndrome (ARS). Although amino acids are key nutrients involved in hematopoietic regulation, the impacts of amino acids on bone marrow hematopoiesis following irradiation and the associated mechanisms have not been fully elucidated. Hence, it is of paramount importance to study the changes in amino acid metabolism after irradiation and their effects on hematopoiesis as well as the related mechanisms.

Background: The challenge of expanding haematopoietic stem/progenitor cells (HSPCs) in vitro has limited their clinical application. Human hair follicle mesenchymal stem cells (hHFMSCs) can be reprogrammed to generate intermediate stem cells by transducing OCT4 (hHFMSCs) and pre-inducing with FLT3LG/SCF, and differentiated into erythrocytes. These intermediate cells exhibit gene expression patterns similar to pre-HSCs, making them promising for artificial haematopoiesis.
