What Our Scientist Says
Column-based cell isolation technologies can be complicated, laborious, and time-consuming. We thought there had to be a better way. That's why we developed the column-free EasySep? cell isolation system.

Isolation of Primary Human Saphenous Vein Endothelial Cells, Human Internal Thoracic Artery Endothelial Cells, and Human Adipose Tissue-Derived Microvascular Endothelial Cells from Patients Undergoing Coronary Artery Bypass Graft Surgery
International Journal of Molecular Sciences 2025 Sep
Abstract
Primary human endothelial cells represent an essential tool to model endothelial dysfunction and to screen interventions for its treatment. Here, we developed a protocol for the synchronous isolation of primary human saphenous vein endothelial cells (HSaVEC), human internal thoracic artery endothelial cells (HITAEC), and human microvascular endothelial cells (HMVEC) from SV and ITA utilized as conduits during coronary artery bypass graft surgery and from subcutaneous adipose tissue excised while providing an access to the heart. Treatment by collagenase type IV and magnetic separation with anti-CD31-antibody-coated beads ensured relatively high efficiency of the isolation (≈60% for HSaVEC, ≈50% for HITAEC, and ≈20% for HMVEC) and high purity (≥99%) of isolated ECs within ≈2 weeks (HSaVEC), ≈2–3 weeks (HITAEC), and ≈3–4 weeks (HMVEC). A colorimetric assay of cell viability and proliferation, as well as real-time bioimpedance monitoring using the xCELLigence instrument, demonstrated high proliferative activity in HSaVEC, HITAEC, and HMVEC, whilst the in vitro tube formation assay indicated their angiogenic potential. The isolation of HSaVEC, HITAEC, and HMVEC from patients undergoing coronary artery bypass graft surgery is a promising option to investigate endothelial heterogeneity, to interrogate endothelial responses to various stresses, and to pinpoint the optimal approaches for restoring endothelial homeostasis, thereby reproducing them within the bedside-to-bench-to-bedside concept.
Protocol for CRISPR-mediated deletion of cis-regulatory element in murine Th17 cells for in vivo assessment of effector function
STAR Protocols 2025 May
Abstract
SummaryStudying the cis-regulatory elements (CREs) of genes in Th17 cells during autoimmune disease progression, such as experimental autoimmune encephalomyelitis (EAE), is often limited by the availability of gene-edited mice. Here, we present a protocol for CRISPR-mediated deletion of a CRE in murine Th17 cells for in vivo assessment of effector function in EAE. We describe steps for dual U6gRNA construction, preparation of retroviruses, viral delivery, and Th17 differentiation. We then detail procedures for in vivo functionality analysis.For complete details on the use and execution of this protocol, please refer to Zhong et al.1,2 Graphical abstract Highlights?Steps for designing and cloning dual U6gRNA cassettes to delete a specific CRE?Instructions for optimized retrovirus production and transduction into CD4+ T cells?Guidance on Th17 differentiation and confirmation of CRE deletion in cultured T cells?Procedures for adoptive transfer of CRISPR-edited Th17 cells to assess in vivo function Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.

Single-cell ultra-high-throughput multiplexed chromatin and RNA profiling reveals gene regulatory dynamics
Nature Methods 2025 May
Abstract
Enhancers and transcription factors (TFs) are crucial in regulating cellular processes. Current multiomic technologies to study these elements in gene regulatory mechanisms lack multiplexing capability and scalability. Here we present single-cell ultra-high-throughput multiplexed sequencing (SUM-seq) for co-assaying chromatin accessibility and gene expression in single nuclei. SUM-seq enables profiling hundreds of samples at the million cell scale and outperforms current high-throughput single-cell methods. We demonstrate the capability of SUM-seq to (1) resolve temporal gene regulation of macrophage M1 and M2 polarization to bridge TF regulatory networks and immune disease genetic variants, (2) define the regulatory landscape of primary T helper cell subsets and (3) dissect the effect of perturbing lineage TFs via arrayed CRISPR screens in spontaneously differentiating human induced pluripotent stem cells. SUM-seq offers a cost-effective, scalable solution for ultra-high-throughput single-cell multiomic sequencing, accelerating the unraveling of complex gene regulatory networks in cell differentiation, responses to perturbations and disease studies. This work presents SUM-seq, an ultra-high-throughput method for co-profiling chromatin accessibility and gene expression in single nuclei across multiplexed samples, advancing the study of gene regulation in diverse biological systems.
