The bio-electrospray technique has been recently pioneered to manipulate living, immortalised and primary cells, including a wide range of stem cells. Studies have demonstrated that the creation of viable, fully functional in vitro microenvironments is possible using this technique. By modifying the bio-electrospray procedure (referred to as cell electrospinning), a variety of microenvironment morphologies have been fabricated. Because bio-electrospraying of biological material is a relatively new technique, it is important to determine if there are any unwanted consequences to the manipulated cells as a result of the procedure. Here, we establish the validity of the process using a heterogeneous, living population of hematopoietic stem/progenitor cells, using a functional in vitro assay and in vivo mouse model to investigate for side-effects that previous in vitro assays may not have detected. Our studies demonstrate that these bio-protocols have no obvious negative effects, thus indicating significant promise for utility in biological sciences and for a plethora of healthcare applications.

Erythropoiesis, a remarkably dynamic and efficient process responsible for generating the daily quota of red blood cells (approximately 280 ± 20 billion cells per day), is crucial for maintaining individual health. Any disruption in this pathway can have significant consequences, leading to health issues. According to the World Health Organization, an estimated 25% of the global population presents symptoms of anemia.

Umbilical cord-derived mesenchymal stromal/stem cells (UC-MSCs) present low immunogenicity and potent immunomodulatory effects for treating various diseases. Human UC-MSCs are a heterogeneous population consisting of three main subpopulations with different cell shapes, proliferation rates, differentiation abilities, and immune regulatory functions. Previously, BAMBIMFGE8 UC-MSCs, the first subgroup successfully isolated from UC-MSCs were found to fail to alleviate lupus nephritis.

Background: Cell therapy demonstrates promising potential as a substitute therapeutic approach for liver cirrhosis. We have developed a strategy to effectively expand murine and human hepatocyte-derived liver progenitor-like cells (HepLPCs) in vitro. The primary objective of the present study was to apply HepLPCs to the treatment of liver cirrhosis and to elucidate the underlying mechanisms responsible for their therapeutic efficacy.

Nonunion is a significant complication in fracture management for surgeons. Salvianolic acid A (SAA), derived from the traditional Chinese plant Salviae miltiorrhizae Bunge (Danshen), exhibits notable anti-inflammatory and antioxidant properties. Although studies have demonstrated its ability to promote osteogenic differentiation, the exact mechanism of action remains unclear.
