Alpha-1 antitrypsin deficiency (AATD) is an autosomal disorder that causes liver and lung disease. The risk of developing lung emphysema, chronic obstructive pulmonary disorder and liver cirrhosis is observed in >75 % people affected with a homozygous mutation. Here, we describe the generation of an induced pluripotent stem cell (iPSC) line from peripheral blood mononuclear cells (PBMC) isolated from a AATD patient using non viral and non-integrating episomal vectors. The iPSC line expresses pluripotency markers, generates three germ layers in vitro and retains a normal karyotype (P20) and can provide an ideal tool for disease modelling, drug screening, and personalized medicine.

Introduction: Mutations in SORL1, encoding the sorting receptor Sortilin-related receptor with A-type repeats (SORLA), are found in individuals with Alzheimer's disease (AD). We studied SORLA, carrying a mutation in its ligand binding domain, to learn more about receptor functions relevant for human brain health.
Methods: We investigated consequences of SORLA expression in induced pluripotent stem cell (iPSC)-derived human neurons and microglia, using unbiased proteome screens and functional cell assays.

Adeno-associated virus (AAV) vectors are widely used in gene therapy, particularly for liver-targeted treatments. However, predicting human-specific outcomes, such as transduction efficiency and hepatotoxicity, remains challenging. Reliable models are urgently needed to bridge the gap between preclinical studies and clinical applications.

Primordial germ cells (PGCs) are the progenitor cells of sperm and eggs. Xenotransplantation of chicken PGCs can achieve germline transmission. However, there are still challenges in obtaining many PGCs from endangered birds in vitro.

Primary microcephaly, a rare congenital condition characterized by reduced brain size, occurs due to impaired neurogenesis during brain development. Through whole-exome sequencing, we identified compound heterozygous loss-of-function mutations in CENTRIN 3 (CETN3) in a 5-year-old patient with primary microcephaly. As CETN3 has not been previously linked to microcephaly, we investigated its potential function in neurodevelopment in human pluripotent stem cell-derived cerebral organoids.

Technological advances and the desire to reduce dependence on animal models have brought human-relevant models to the forefront of drug development. This paradigm shift is leveraging the advances in systems and new approach methodologies (NAMs), which was the focus of a workshop convened by the Health and Environmental Sciences Institute (HESI) in May 2024. Highlights included discussions on predicting cardiac failure modes and the utility of human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), microfluidic systems like BioFlux™, and engineered heart tissues in enhancing early-stage drug safety assessments.
