Stem cell therapy may be a suitable approach for the treatment of many neurodegenerative diseases. However, one major impediment to the development of successful cell-based therapies is our limited understanding of the mechanisms that instruct neural stem cell behaviour, such as proliferation and cell fate specification. The β-amyloid precursor protein (APP) of Alzheimer's disease (AD) may play an important role in neural stem cell proliferation and differentiation. Our recent work shows that in vitro, APP stimulates neural stem or progenitor cell proliferation and neuronal differentiation. The effect on proliferation is mediated by an autocrine factor that we have identified as cystatin C. As cystatin C expression is also reported to inhibit the development of amyloid pathology in APP transgenic mice, our finding has implications for the possible use of cystatin C for the therapy of AD.

Dysregulated lipid metabolism within the tumor microenvironment (TME) is a critical hallmark of cancer progression, with lipids serving as a major energy source for tumor cells. Beyond their role in cell membrane synthesis, lipids also provide essential substrates for biomolecule production and activate signaling pathways that regulate various cellular processes. Aberrant lipid metabolism impacts not only function but also alters the behavior of immune and stromal cells within the TME.

Intrauterine Adhesions (IUA) are a significant cause of infertility and miscarriage, often resulting from trauma to the endometrium. While hysteroscopic adhesiolysis is the primary treatment, the use of hydrogels as anti-adhesion barriers and drug delivery systems is gaining traction for improving patient outcomes. This review aims to explore various hydrogel types, their role in tissue repair, and the integration of stem cell therapy.

As light sheet fluorescence microscopy (LSFM) becomes widely available, reconstruction of time-lapse imaging will further our understanding of complex biological processes at cellular resolution. Here, we present a comprehensive workflow for in toto capture, processing, and analysis of multi-view LSFM experiments using the ex vivo mouse embryo as a model system of development. Our protocol describes imaging on a commercial LSFM instrument followed by computational analysis in discrete segments, using open-source software.

CD226 plays a vital role in natural killer (NK) cell cytotoxicity, interacting with its ligands CD112 and CD155 to initiate immune synapse formation, primarily through leukocyte function-associated-1 (LFA-1). Our study examined the role of CD226 in NK cell surveillance of acute myeloid leukemia (AML). NK cells in patients with AML had lower expression of CD226.
