Adipose-derived regenerative cells (ADRCs) also referred to as the stromal vascular fraction, provide an ample source of stem cells with widespread regenerative therapeutic use. Being heterogenous in nature, possibly affecting the clinical outcome after stem cell treatment, the ADRC- donor, -BMI, and -gender may have a large impact on ADRC composition and quality but this remains largely unexplored. Herein, we provide a comprehensive single-cell RNA sequencing ADRC mapping across two cell trial intervention studies but found no gender- or BMI-related variations, except for a minor female increase in PI16/CD55-expressing stem cells. Indeed, ADRC heterogeneity was surprisingly minimal between donors. This provides important decision-making support on adipose stem cell donor selection for stem cell treatments, and suggest that donor, gender and BMI should be regarded as less influential.

Postoperative abdominal adhesions are the leading cause of bowel obstruction and a cause of chronic pain and infertility. Adhesion formation occurs after 50 to 90% of abdominal operations and has no proven preventative or treatment strategy. Abdominal adhesions derive primarily from the visceral peritoneum and are composed of polyclonally proliferating tissue-resident fibroblasts.

Objective: This study aims to investigate and analyze the differentially expressed genes (DEGs) in CD34 + hematopoietic stem cells (HSCs) from patients with myelodysplastic syndromes (MDS) through bioinformatics analysis, with the ultimate goal of uncovering the potential molecular mechanisms underlying pathogenesis of MDS. The findings of this study are expected to provide novel insights into clinical treatment strategies for MDS.
Methods: Initially, we downloaded three datasets, GSE81173, GSE4619, and GSE58831, from the public Gene Expression Omnibus (GEO) database as our training sets, and selected the GSE19429 dataset as the validation set.

Currently, most cell or tissue transplantations using induced pluripotent stem cells (iPSCs) are anticipated to involve allogeneic iPSCs. However, the immunological properties of iPSCs in an allogeneic setting are not well understood. We previously established a mouse transplantation model of MHC-compatible/minor antigen-mismatched combinations, assuming a hypoimmunogenic iPSC-setting.

Human cerebral organoids (hCOs) provide an excellent model for the study of human brain development and disease. Here, we present a protocol to obtain hCOs directly from two-dimensional (2D) pluripotent stem cell (PSC) cultures, avoiding cell dissociation and posterior embryoid body (EB) aggregation. We describe steps for subjecting 2D cultures to a neural fate and subsequently developing hCOs.

Plasmacytoid dendritic cells (pDCs) play a pivotal role in immune responses, particularly against viral infections. pDCs exhibit diverse functions, including interferon production, cytokine secretion, and antigen presentation. Here, we investigate the antigen cross-presentation capacity of pDCs and their role in CD8 T cell activation.
