Pluripotency is tightly regulated and is crucial for stem cells and their implementation for regenerative medicine. Non-coding RNAs, especially long non-coding RNAs (lncRNAs) emerged as orchestrators of versatile (patho)-physiological processes on the transcriptional and post-transcriptional level. Cyrano, a well-conserved lncRNA, is highly expressed in stem cells suggesting an important role in pluripotency, which we aimed to investigate in loss-off-function (LOF) experiments. Cyrano was described previously to be essential for the maintenance of mouse embryonic stem cell (ESC) pluripotency. In contrast, using different genetic models, we here found Cyrano to be dispensable in murine and human iPSCs and in human ESCs. RNA sequencing revealed only a moderate influence of Cyrano on the global transcriptome. In line, Cyrano-depleted iPSCs retained the potential to differentiate into the three germ layers. In conclusion, different methods were applied for LOF studies to rule out potential off-target effects. These approaches revealed that Cyrano does not impact pluripotency.

Wound healing is a dynamic and complex process that consists of four interconnected phases: hemostasis, inflammation, proliferation, and remodeling. This complex process is based on the coordinated actions of growth factors, cytokines, and other cellular interactions. However, conditions such as diabetes and chronic illnesses can disrupt this process and lead to nonhealing wounds or chronic ulcers.

Background: Neurotraumatic conditions, such as spinal cord injury, brain injury, and neurodegenerative conditions, such as amyotrophic lateral sclerosis, pose a challenge to the field of rehabilitation for its complexity and nuances in management. For decades, the use of cell therapy in treatment of neurorehabilitation conditions have been explored to complement the current, mainstay treatment options; however, a consensus for standardization of the cell therapy and its efficacy has not been reached in the medical community. This study aims to provide a comparative review on the very topic of cell therapy use in neurorehabilitation conditions in an attempt to bridge the gap in knowledge.

Contemporary sources report 64 cases of SOMET used in the treatment of bilateral LSCD: 35 cases of chemical burns, 16 of thermal burns, 7 cases of Stevens-Johnson syndrome, 1 keratitis, 1 cicatricial pemphigoid, 1 dermoid, 1 case of drug-induced LSCD (mitomycin C), etc. Notably, all transplantations resulted in complete epithelialization, and in 3 cases, penetrating keratoplasty was subsequently performed with favorable functional and anatomical outcomes.

Unlabelled: Oncogenes amplified on extrachromosomal DNA (ecDNA) contribute to treatment resistance and poor survival across cancers. Currently, the spatiotemporal evolution of ecDNA remains poorly understood. In this study, we integrate computational modeling with samples from 94 treatment-naive human glioblastomas (GBM) to investigate the spatiotemporal evolution of ecDNA.

Innate immune cells can acquire a memory phenotype, termed trained immunity, but the mechanism underlying the regulation of trained immunity remains largely elusive. Here, we demonstrate that inhibition of Aurora kinase A (AurA) dampens trained immunity induced by β-glucan. ATAC-seq and RNA-seq analysis reveal that AurA inhibition restricts chromatin accessibility of genes associated with inflammatory pathways such as JAK-STAT, TNF, and NF-κB pathways.
