Tissue Microenvironment Cell Sorting Service
InquiryObesity is no longer viewed simply as a disorder of lipid storage but as a complex systemic disease driven by the remodeling of the adipose tissue microenvironment (ATM). The transition from healthy expansion to pathological dysfunction involves a sophisticated interplay between adipocytes, immune cells, vascular endothelial cells, and the extracellular matrix.
Tissue Microenvironment Cell Sorting for Obesity Research
Protheragen provides a specialized tissue microenvironment cell sorting service designed to deconstruct these complex cellular networks. By utilizing advanced dissociation protocols and high-parameter sorting, we enable researchers to isolate specific subpopulations—such as lipid-associated macrophages (LAMs), fibro-inflammatory progenitors, and regulatory T cells—with unparalleled purity. Our service is tailored for preclinical obesity research, providing the high-quality cellular input required for downstream single-cell RNA sequencing (scRNA-seq), metabolic profiling, and functional assays that define the next generation of metabolic therapeutics.
Core Technologies
To capture the true state of the obese microenvironment, Protheragen employs a suite of proprietary and optimized technologies:
- Cold-Active Protease Dissociation
Traditional warm digestion often triggers heat-shock gene expression, masking the true inflammatory profile of obese tissue. We utilize cold-active enzymatic cocktails to maintain the native transcriptional state.
- High-Parameter Flow Cytometry (FACS)
Our platforms support 30+ color panels, allowing for the simultaneous isolation of rare immune subsets and stromal vascular fraction (SVF) components.
- Large-Particle Sorting
We utilize specialized nozzles and pressure settings to sort fragile, large cells like adipocytes and lipid-laden foam cells without compromising membrane integrity.
- Microfluidic-Based Enrichment
For low-abundance progenitor populations, we utilize microfluidic sorting to maximize recovery rates from small preclinical biopsies.

Service Scope
Our sorting services cover the full spectrum of the obesity-related microenvironment:
- Adipose Immune Profiling
Isolation of CD11c+ proinflammatory macrophages, CD8+ T cells, and ILC2s.
- Stromal Vascular Fraction (SVF) Analysis
Separation of pre-adipocytes, mesenchymal stem cells (MSCs), and vascular endothelial cells.
- Multi-Organ Interaction Studies
Sorting of infiltrating cells from the "obese" liver (NAFLD/NASH models) and skeletal muscle.
- High-Fat Diet (HFD) Response Tracking
Longitudinal sorting of cells to track the evolution of the microenvironment during weight gain or therapeutic intervention.
Workflow
The Protheragen workflow is engineered for reproducibility and cellular viability, ensuring that your preclinical samples yield actionable data.
Fields of Application
Our tissue microenvironment cell sorting service serves as a foundational bridge between complex tissue architecture and high-resolution molecular analysis, empowering a wide array of preclinical research objectives.
- Single-Cell Multi-omics: Preparing ultra-pure cell suspensions for scRNA-seq, ATAC-seq, and CITE-seq to map the obese landscape.
- Drug Target Discovery: Identifying specific cell surface markers on dysfunctional adipocyte progenitors for antibody-drug conjugate (ADC) development.
- Inflammation Research: Studying the recruitment of myeloid cells to the ATM and their role in insulin resistance.
- Thermogenesis Studies: Isolating "beige" adipocyte precursors to evaluate the efficacy of metabolic activators.
Advantages
Protheragen sets the standard for preclinical obesity research through specialized expertise in handling challenging, lipid-heavy samples.
Unmatched Purity in Lipid-Rich Environments
Standard flow cytometry often fails in the face of "oily" samples. We have engineered specialized delipidation and filtration protocols that remove lipid droplets and debris without compromising cellular viability.
Preservation of Metabolic States
Obese tissue is notoriously reactive. Mechanical and enzymatic dissociation can inadvertently trigger inflammatory cascades, skewing your results. We utilize cold-active dissociation and metabolic inhibitors to "freeze" the cellular state, ensuring that the inflammatory markers you measure reflect the animal's physiology, not the processing lab's environment.
Customized Panel Expertise
Skip the months of optimization. We offer pre-validated assay panels for Obesity Models in rodents, non-human primates (NHPs), and other species, helping to reduce your assay development time.
High-Fidelity Biological Profiling
Our optimized isolation protocols ensure maximal preservation of native cellular states, yielding high-purity populations with unrivaled intra-study consistency. This level of technical reproducibility ensures your datasets are robust, and definitive.

Customer Review
Breaking Barriers in Myeloid Infiltration Studies
"Working with Protheragen revolutionized our study on macrophage polarization in the obese niche. Their ability to isolate highly viable, lipid-laden cells allowed us to capture a transient inflammatory state we previously missed using standard digestion methods. Their technical team feels like an extension of our own lab."Dr. D.A., Metabolic Disease Research Institute
Accelerating High-Throughput Progenitor Discovery
"The purity of the fibro-adipogenic progenitors we received was exceptional. Protheragen handled the logistics of our large-scale HFD mouse study flawlessly, providing consistent results across multiple cohorts. We are already planning our next series of NHP sorting projects with them."Dr. D.P., Biopharma Group
Frequently Asked Questions
-
How do you handle the high autofluorescence typical of obese adipose tissue?
We utilize advanced compensation matrices and specific "dump channels" to exclude autofluorescent debris, ensuring only true positive cells are collected.
-
Can you sort mature adipocytes?
Yes, we utilize large-bore nozzles (100-130μm) and low-pressure settings specifically calibrated for the fragility of mature, lipid-laden cells.
-
What is the minimum tissue weight required?
While it varies by cell type, we have successfully isolated rare populations from as little as 50mg of adipose tissue.
-
How do you ensure the cells don't change their expression profile during the sort?
Our "cold-chain workflow" keeps samples at 4°C throughout dissociation and sorting to "freeze" the transcriptional profile.
-
Do you provide services for non-adipose tissues in obesity models?
Absolutely. We frequently sort cells from the liver, spleen, and hypothalamus of obese preclinical models.
-
Can I send frozen tissue?
For live cell sorting, fresh tissue is preferred; however, we offer nuclear sorting (snRNA-seq prep) for flash-frozen samples.
-
What is the typical purity of a sorted population?
We routinely achieve >95-98% purity, depending on the initial frequency of the target population.
-
How long does the process take?
Most tissue-to-sorted-cell workflows are completed within 4-6 hours to ensure maximum viability.
-
Do you offer functional assays post-sort?
Yes, we can transition sorted cells directly into metabolic flux analysis or co-culture experiments.
