Hypertrophic cardiomyopathy (HCM) is a frequent cardiovascular pathology caused by a huge number of mutations in sarcomere-associated proteins. This genetic diversity leads to differences in pathogenetic mechanisms and hampers HCM therapy. Cardiomyocytes derived from patient-specific induced pluripotent stem cells give new opportunities for studying underlying HCM mechanisms. We generated an iPSC line from peripheral blood mononuclear cells of an HCM patient with a heterozygous p.E510Q mutation in HADHA using non-integrating episomal vectors. The iPSC line showed typical morphology, expression of pluripotency markers, capacity to be differentiated into derivatives of three germ layers, and presence of the patient-specific mutation.

One hallmark of cancer is the upregulation and dependency on glucose metabolism to fuel macromolecule biosynthesis and rapid proliferation. Despite significant pre-clinical effort to exploit this pathway, additional mechanistic insights are necessary to prioritize the diversity of metabolic adaptations upon acute loss of glucose metabolism. Here, we investigated a potent small molecule inhibitor to Class I glucose transporters, KL-11743, using glycolytic leukemia cell lines and patient-based model systems.

There are few in vitro models available to study microglial physiology in a homeostatic context. Recent approaches include the human induced pluripotent stem cell model, but these can be challenging for large-scale assays and may lead to batch variability. To advance our understanding of microglial biology while enabling scalability for high-throughput assays, we developed an inducible immortalized murine microglial cell line using a tetracycline expression system.

Prostate cancer (PCa) is the most common malignant tumor of the male reproductive system. In this study, we establish an induced pluripotent stem cell (iPSC) line from a male diagnosed with PC. of This iPSCs line was generated from the peripheral blood mononuclear cells (PBMCs) using a non-integrated Sendai virus.

Myocardial infarction can lead to the loss of billions of cardiomyocytes, and while cell-based therapies are an option, immature nature of in vitro-generated human induced pluripotent stem cell (iPSC)-derived cardiomyocytes (iCMs) is a roadblock to their development. Existing iPSC differentiation protocols don't go beyond producing fetal iCMs. Recently, adult extracellular matrix (ECM) was shown to retain tissue memory and have some success driving tissue-specific differentiation in unspecified cells in various organ systems.

The neuromuscular junction (NMJ) is essential for transmitting signals from motor neurons (MNs) to skeletal muscles (SKMs), and its dysfunction can lead to severe motor disorders. However, our understanding of the NMJ is limited by the absence of accurate human models. Although human induced pluripotent stem cell (iPSC)-derived models have advanced NMJ research, their application is constrained by challenges such as limited differentiation efficiency, lengthy generation times, and cryopreservation difficulties.
