Duchenne muscular dystrophy (DMD) is an X-linked disease caused by mutations in the DMD gene, which spans ~2.4Mb of genomic sequence at locus Xp21. This mutation results in the loss of the protein dystrophin. DMD patients die in their second or third decade due to either respiratory failure or cardiomyopathy, as the absence of dystrophin leads to myofiber membrane fragility and necrosis, eventually resulting in muscle atrophy and contractures. Currently, there is no effective treatment for DMD, therefore induced pluripotent stem cells from DMD patients would be a powerful tool for studying disease mechanisms.

Background: Cystic Fibrosis-related Bone Disease is an emerging challenge faced by 50 % of adult people with cystic fibrosis (CF). The multifactorial causes of this comorbidity remain elusive. However, congenital bone defects have been observed in animal models with CFTR mutations, suggesting its importance.

Human pluripotent stem cells (hPSCs) provide a powerful platform for generating hematopoietic progenitor cells (HPCs) and investigating hematopoietic development. Here, we present a protocol for maintaining hPSCs and inducing their differentiation into HPCs through the endothelial-to-hematopoietic transition (EHT) on vitronectin-coated plates. We outline steps for evaluating the efficiency of HPC generation and assessing their potential to differentiate into various hematopoietic lineages.

- FT596 is a novel cancer therapy using iPSC-derived CAR NK cells targeting CD19, designed to assess its safe dosage and effectiveness alone and with rituximab in patients with B-cell lymphoma.
- This phase 1 trial involved patients with relapsed or refractory B-cell lymphoma, administering FT596 after chemotherapy, with separate regimens for those receiving rituximab and those who did not.
- The study measured potential side effects while determining the optimal dose of FT596 and allowed modifications to the treatment based on patient tolerance and response.

Tris (1, 3-dichloro-2-propyl) phosphate (TDCPP) is an extensively used organophosphorus flame retardant (OFR). Previous studies have suggested that it has neurotoxic effects, but the neurotoxicity mechanism is still unclear. Neural stem cells are an important in vitro model for studying the neurotoxicity mechanism of pollutants.

Induced pluripotent stem cell (iPSC)-derived natural killer (NK) cells offer an opportunity for a standardized, off-the-shelf treatment with the potential to treat a wider population of acute myeloid leukaemia (AML) patients than the current standard of care. FT538 iPSC-NKs express a high-affinity, noncleavable CD16 to maximize antibody dependent cellular cytotoxicity, a CD38 knockout to improve metabolic fitness, and an IL-15/IL-15 receptor fusion preventing the need for cytokine administration, the main source of adverse effects in NK cell-based therapies. Here, we sought to evaluate the potential of FT538 iPSC-NKs as a therapy for AML through their effect on AML cell lines and primary AML cells.
