实验数据

Figure 1. mTeSR™ Plus Maintains Optimal pH Levels Throughout a Weekend-Free Protocol

The pH of spent medium from hPSCs cultured in mTeSR™ Plus is higher than that of hPSCs cultured in mTeSR™1 and other flexible-feeding medium at similar cell densities. pH and cell numbers were measured after a 72-hour period without feeding. Range of cell numbers shown represent different densities that would be observed throughout a typical passage. This demonstrates that feeds can be skipped for two days at any time during routine maintenance using mTeSR™ Plus while maintaining a pH above 7.0. Note: Cultures were fed double the standard medium volume prior to the 72-hour period without feeds in all media and cell numbers are from one well of a 6-well plate.

Figure 2. mTeSR™ Plus Maintains Consistent Levels of FGF2 Throughout a Weekend-Free Protocol

FGF2 levels remain high in mTeSR™ Plus when cultured at 37°C over a 72 hour time period. Measured by ELISA.

Figure 3. mTeSR™ Plus Supports Higher Cell Numbers

Growth curves were obtained for human ES (H9) cells cultured in mTeSR™1 or mTeSR™ Plus on Corning® Matrigel® matrix over 7 days with either daily feeds or restricted feeds. Growth curves were determined by seeding 20,000 cells per well of a 6-well plate as aggregates and counting the cell numbers each day in duplicate wells.

Figure 4. Larger Colonies are Observed in mTeSR™ Plus Cultures

The average colony size per passage (± SEM) was obtained for human ES (H1, H9) and iPS (STiPS-M001, WLS-1C) cells cultured in mTeSR™1 (daily feeds) or mTeSR™ Plus (restricted feeds) on Corning® Matrigel® over 10 passages. Size was determined by measuring representative colony diameters at harvest. Note that this data is representative of cultures passaged at a 7-day passaging interval; smaller colony size should be expected if using shorter passaging intervals.

Figure 5. Normal human ES and iPS Cell Morphology is Observed in mTeSR™ Plus Cultures

Images depict undifferentiated human hES (H1) and iPS (WLS-1C) cells cultured on Corning®️ Matrigel®️ matrix in mTeSR™1 with daily feeds or mTeSR™ Plus with restricted feeds. Cells retain the prominent nucleoli and high nuclear-to-cytoplasmic ratio characteristic of this cell type after 10 passages. Densely packed cells and multi-layering are prominent when cells are ready to be passaged.

Proteomics of Patient-Derived Striatal Medium Spiny Neurons in Multiple System Atrophy N. J. Smandzich et al. Cells 2025 Sep

Abstract

The rare and rapidly progressive neurodegenerative disease multiple system atrophy (MSA) mainly affects the striatum and other subcortical brain regions. In this atypical Parkinsonian syndrome, the protein alpha-synuclein aggregates and misfolds in neurons as well as glial cells and is released in elevated amounts by hypoexcitable neurons. Mitochondrial dysregulation affects the biosynthesis of coenzyme Q10 and the activity of the respiratory chain, as shown in an induced pluripotent stem cell (iPSC) model. Proteome studies of cerebrospinal fluid and brain tissue from MSA patients yielded inconsistent results regarding possible protein changes due to small and combined groups of atypical Parkinsonian syndromes. In this study, we analysed the cellular proteome of MSA patient-derived striatal GABAergic medium spiny neurons. We observed 25 significantly upregulated and 16 significantly downregulated proteins in MSA cell lines compared to matched healthy controls. Various protein types involved in diverse molecular functions and cellular processes emphasise the multifaceted pathomechanisms of MSA. These data could contribute to the development of novel disease-modifying treatment strategies for MSA patients.

Selective agonists of KIR and NKG2A to evade missing self response of natural killer cells S. Hiura et al. Scientific Reports 2025 Sep

Abstract

Immune rejection is one of the most serious challenges in allogeneic transplantation, including allogeneic induced pluripotent stem cell (allo-iPSC)-derived cell therapy. Beta-2-Microglobulin gene-knockout, human leukocyte antigen (HLA) class I-deficient iPSCs can evade immune rejection by host T cells, which occurs due to HLA mismatches. However, natural killer (NK) cells recognize HLA class Ⅰ-deficient cells and reject them, which is known as the missing-self response. Introducing chimeric HLA-E protein to HLA class Ⅰ-deficient iPSCs suppresses the missing-self response of NK cells expressing the inhibitory receptor NKG2A; however, technology to suppress NKG2A-negative NK cells is still required. Here, we developed novel agonists for the other inhibitory receptor, killer immunoglobulin receptor (KIR), on NK cells. We found that antibodies that bind to activating KIR enhance NK cell activation and developed selective agonists for inhibitory KIRs (KIR2DL1, KIR2DL2/3, and KIR3DL1). Introducing these selective inhibitory KIR agonists on T cells and HLA class Ⅰ-deficient iPSCs allowed them to evade immune rejection by NK cells. Additionally, we identified an NKG2A-selective agonist as an alternative to chimeric HLA-E, which stimulates the activating receptor NKG2C. This technology enhances immune tolerance in allo-iPSCs and facilitates the development of various iPSC-derived regenerative medicines.

Reaching a cell monolayer at the end of hiPSC differentiation enhances neural crest lineage commitment F. M. Duarte et al. PLOS One 2025 Sep

Abstract

Neural crest stem cells (NCSCs) compose a highly migratory, multipotent, stem cell population arising from the neural plate border of the embryonic ectoderm. Investigating the development of NCSCs is critical in understanding both embryonic development and abnormal events that underlie neurocristopathies. Suggested seeding densities in in vitro human induced pluripotent stem cells (hiPSCs) differentiation protocols, varying between 10,000 cells/cm 2 and 200,000 cells/cm 2 , demonstrate a lack of consensus on the optimal conditions to obtain NCSCs. Aiming to maximize the differentiation efficiency of hiPSCs towards the NCSCs lineage, we investigated the effect of the initial seeding density on NCSCs lineage commitment, both in fibroblast- and human peripheral blood mononuclear cell (PBMC)-derived hiPSCs. Cultures were characterized with gene and protein expression analysis assessing stemness ( OCT3/4 and NANOG ), neural crest identity ( SNAI2 and SOX10 ) and neuroectoderm identity ( PAX6 and SOX1 ). We demonstrate that reaching a confluent monolayer of cells by the end of the differentiating protocol is crucial to obtaining NCSCs from hiPSCs. To achieve this, our results indicated 17,000 cells/cm 2 is the optimal initial seeding density. Under this protocol, a confluent monolayer was reached after 8 days of differentiation and an average of 89% SOX10 positive cells were obtained. The fold change of SNAI2 and SOX10 expression was 11-fold and 17-fold higher, respectively, in cultures seeded with 17,000 cells/cm 2 , compared to the highest tested density of 200,000 cells/cm 2 . In contrast, seeding 200,000 cells/cm 2 induced neuroectoderm-like cells, confirmed by an average of 45% of cells marking positive for PAX6. With this work, we demonstrate the importance of achieving cellular confluency during NCSCs differentiation.
