Cellular therapy for the peripheral arterial disease treatment: Protocol for a systematic review and meta-analysis.

Cellular therapy is a promising treatment option for Peripheral Arterial Disease (PAD). Different cell types can be used to regenerate and repair tissues affected by PAD. Many studies have proposed the use of stem cells, such as mesenchymal stem cells, or even mononuclear cells isolated from peripheral blood or bone marrow, to treat PAD.

Using advanced cell staining and sorting strategies, we isolated populations of VSELs and HSCs for bulk RNA-Seq analysis to compare the transcriptomic profiles of both cell populations. Libraries were prepared from an extremely small number of cells; however, their good quality was preserved, and they met the criteria for sequencing.

Hematopoietic stem cells (HSCs) rely on self-renewal to sustain stem cell potential and undergo differentiation to generate mature blood cells. Mitochondrial fatty acid β-oxidation (FAO) is essential for HSC maintenance. However, the role of Carnitine palmitoyl transferase 1a (CPT1A), a key enzyme in FAO, remains unclear in HSCs.

Department of Pediatrics, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, Zheiiang, China.
To illustrate the potential of mesenchymal stem cell-derived exosomes (MSC-Exos) in mitigating septic lung injury by reducing the excessive formation of neutrophil extracellular traps (NETs), a mouse model of septic lung injury was induced through cecal ligation and puncture (CLP). The mice received intraperitoneal injections of MSC-Exos. Post injection, pathological alterations of the lung tissue were evaluated through HE staining, and the levels of inflammatory markers in each mouse group at various time points were assessed using ELISA kits.

Hematopoietic stem cells are a unique population of tissue-resident multipotent cells with an extensive ability to self-renew and regenerate the entire lineage of differentiated blood cells. Stem cells reside in a highly specialized microenvironment with surrounding supporting cells, forming a complex and dynamic network to preserve and maintain their function. The survival, activation, and quiescence of stem cells are largely influenced by niche-derived signals, with aging niche contributing to a decline in stem cell function.
