Cloud-Clone expands primary cardiac cell portfolio for microenvironment research

Cloud-Clone says it now offers seven categories of primary cardiac cells to help researchers model heart microenvironments more accurately for disease, drug screening and translational studies. The portfolio spans multiple species and includes cells tied to fibrosis, endothelial signaling, valve disease and pericardial biology.

Why it matters: - Cardiovascular research is moving from single-cell studies to models that capture how multiple heart cell types interact. - Cloud-Clone’s expanded primary-cell portfolio is designed to help researchers better reproduce cardiac microenvironments that drive disease. - The approach supports drug screening, mechanistic studies and translational work that may be closer to real physiology than monocultures.

What happened: - Cloud-Clone introduced a portfolio covering seven major categories of primary cardiac cells. - The lineup includes cardiomyocytes, cardiac microvascular endothelial cells, cardiac fibroblasts, pericardial fibroblasts, cardiac valve interstitial cells, pericardial mesothelial cells and endocardial fibroblasts. - The company positions the collection as a toolset for cardiovascular mechanistic exploration and in-vitro disease modeling. - Researchers are directed to the company’s website for inventory, quality-control data and technical documents.

The details: - Cloud-Clone says its primary-cell development uses in-house SPF-grade animal facilities and an ISO-certified quality control system. - The cardiovascular collection spans more than 10 species, including rat, mouse, rabbit, dog, cat, pig, sheep, guinea pig, chicken and human. - Feline cardiomyocytes, catalog CSI007Fe01, are isolated by enzymatic digestion and differential adhesion, with purity above 85% and viability over 80%. - Feline cardiomyocytes retain spontaneous rhythmic beating and are presented as suitable for long-term drug mechanism and toxicology studies. - Cardiac microvascular endothelial cells are supplied from cats, dogs, rats, rabbits and other species. - Cardiac fibroblasts are supplied from rats, mice, rabbits, dogs and other species. - Pericardial fibroblasts and pericardial mesothelial cells are offered as paired tools for pericardial microenvironment studies. - Cardiac valve interstitial cells are available from dogs, sheep, rats, rabbits and more species. - Endocardial fibroblasts are supplied from dogs, sheep, rats and rabbits, and epicardial fibroblasts from dogs and rabbits. - Cloud-Clone says the portfolio supports ischemia/reperfusion models, cardiotoxicity screening, angiogenesis research, fibrosis studies, valve calcification studies and cardiac development or repair work. - The collection is also positioned for co-culture systems that model hypertrophy, remodeling and inflammatory injury.

Between the lines: - The release reflects a broader shift in cardiovascular research toward multicellular and tissue-level systems. - The multi-species approach is meant to support both basic research and preclinical translation, especially where human-like anatomy or cross-species comparison matters. - The emphasis on pericardial, endocardial and epicardial cell types suggests Cloud-Clone is trying to cover the heart as a full anatomical microenvironment, not just the myocardium.

What's next: - Cloud-Clone says it will keep expanding its primary-cell portfolio. - The company says it aims to lower technical barriers for building in-vitro cardiac microenvironment models and support new-drug development and translational medicine. - Researchers can check real-time inventory and supporting documents through the company website.
