This systematic review (PROSPERO CRD42024532621) analyzed studies on human MUSE cell isolation, characterization, and translational potential through searches of the PubMed, Scopus, and Web of Science databases in April 2024. The TIDieR and SYRCLE checklists were used to assess the risk of bias. Our findings identified 34 studies that followed the PRISMA guidelines for assessing different tissue sources, isolation techniques, and characterization methods. MUSE cells are primarily obtained from bone marrow mesenchymal stem cells, and fluorescence-activated cell sorting is the predominant isolation method. Characterization was mainly performed using SSEA-3 immunodetection (positivity ranged from <1% to 6.30%) and was linked to the expression of pluripotency and mesenchymal markers. These findings highlight the relevance of MUSE cells in regenerative medicine as a distinct pluripotent subpopulation within adult mesenchymal tissues. In addition, SSEA-3-based isolation approaches complemented by functional assays has emerged as a key methodological approach for the reliable identification and characterization of MUSE cells. However, isolation efficiency varies depending on the cell source and method.

Our goal is to determine how dysregulation of HOX gene expression promotes colorectal cancer (CRC) development through aberrant SC regulatory mechanisms. We investigated retinoic acid (RA) and WNT signaling because they regulate HOX expression and both pathways are dysregulated in cancer. Previously, we reported WNT and RA pathways are functionally linked, and in CRC, APC mutation generates a WNT:RA imbalance leading to incomplete differentiation and SC overpopulation. We hypothesize that aberrant WNT- and RA-signaling dysregulates HOX expression that contributes to the SC origin of CRC. We discovered a HOX expression signature of eight genes (six-upregulated, two-downregulated) that are significantly altered in CRC, and that predict poor CRC patient survival. NanoString profiling of fluorescence activated cell sorted SC subpopulations, bioinformatics studies, and RNA-seq analysis of fresh colon tissues revealed: (1). The six-upregulated genes are regulated by RA signaling; (2). ATRA-treatment of CRC cells, but not wt-APC induction or RARA knockout, leads to a HOX expression pattern matching the HOX signature; (3). Mid-cluster (group 3) HOXB gene expression characterizes normal colon, but increased group 3 HOXC expression occurs in CRC; (4). LGR5+ SCs selectively express group 3 HOXB genes while ALDH+ SCs express group 3 HOXC genes; (5). HOXA13 and HOXB13 which are downregulated and predict poor patient survival likely possess tumor-suppressor activity and function by retro-inhibition of earlier HOX genes.

In response, biologically targeted therapies have emerged to directly modulate the cellular and molecular mechanisms underlying muscle degeneration. Current strategies focus on 3 major approaches: regenerative cell-based therapies that promote muscle regeneration and suppress fibrosis; signaling pathway modulation to disrupt pathological tissue remodeling; and metabolic interventions aimed at restoring mitochondrial function and correcting lipid metabolism. Central to these strategies is the regulation of dysfunctional cellular populations within the muscle microenvironment, particularly those responsible for fibrotic and adipogenic changes.

One of the contributing factors is the use of human serum albumin (HSA), which has been widely regarded as essential for supporting ex vivo maintenance, expansion, and differentiation of human stem cells and their derivatives. The lot-to-lot variation of this critical reagent can contribute to inconsistent laboratory results and high manufacturing costs.

Our differentiation method demonstrates robust HSPC generation across various embryonic and induced PSC lines and culture conditions, highlighting its adaptability and reliability. Importantly, PSC-derived HSPCs exhibit functional versatility in differentiation capacity into myeloid and lymphoid lineages, as validated through colony-forming assays as well as directed red blood cell and NK cell differentiations.
