AI Article Synopsis

  • Human adult stem cells and induced pluripotent stem cells are valuable for studying human biology and diseases, and they can form organ-like structures called organoids in supportive environments.
  • Organoids have made significant progress in stem cell research but still face challenges such as inconsistency, limited capabilities, and small size.
  • Recent advanced methods are being developed to enhance the biological accuracy and relevance of organoids, providing new opportunities for harnessing the potential of stem cells.

Article Abstract

Human adult stem cells and patient-derived induced pluripotent stem cells represent promising tools to understand human biology, development, and disease. Under a permissive environment, stem cell derivatives can self-organize and reconstruct their native milieu, resulting in the creation of organ-like entities known as organoids. Although organoids represent a breakthrough in the stem cell field, there are still considerable shortcomings preventing their widespread use, namely their variability, limited function, and reductionist size. In the past few years, sophisticated methodologies have been proposed to allow the design of organoids with improved biological fidelity and physiological relevance. Here, we summarize these emerging technologies and provide insights into how they can be utilized to fulfill the potential of stem cells.

Background: Current treatments for penile erectile structures reconstruction are limited and remain a great challenge in clinical practice. Tissue engineering techniques using different seed cells and scaffolds to construct a neo-tissue open promising avenues for penile erectile structures repair and replacement and show great promise in the restoration of: structure, mechanical property, and function which matches the original tissue.

Methods: A comprehensive literature review was conducted by accessing the NCBI PubMed, Cochrane, and Google Scholar databases from January 1, 1990, to January, 1, 2022 using the search terms "Tissue engineering, Corpus cavernosum (CC), Tunica albuginea (TA), Acellular Matrix, Penile Reconstruction".

Intestinal organoid co-culture systems: current approaches, challenges, and future directions.

Am J Physiol Gastrointest Liver Physiol

Health and Biosecurity, CSIRO,, Sydney, New South Wales Australia.

The intestinal microenvironment represents a complex and dynamic ecosystem, comprising a diverse range of epithelial and non-epithelial cells, a protective mucus layer, and a diverse community of gut microbiota. Understanding the intricate interplay between these components is essential for uncovering the mechanisms underlying intestinal health and disease. The development of intestinal organoids, 3D mini-intestines that closely mimic the architecture, cellular diversity, and functionality of the intestine, offers a powerful platform for investigating different aspects of intestinal physiology and pathology.

Isolating Synaptic Vesicles from Neurospheres for Proteomics.

Methods Mol Biol

December 2024

Laboratory of Neuroproteomics, Department of Biochemistry and Tissue Biology, Institute of Biology, University of Campinas, Campinas, Brazil.

This chapter presents an optimized method for isolating synaptic vesicles (SVs) from neurospheres derived from human induced pluripotent stem cells (hiPSCs). The protocol begins with neurosphere cultivation to achieve mature neurons, which is essential for the functional studies of neuronal activity. Following this, neurosphere-derived synaptosomes are isolated, and SVs are enriched through differential centrifugation.

Traumatic brain injury (TBI) is a significant contributor to global mortality and morbidity, with emerging evidence indicating a heightened risk of developing Alzheimer's disease (AD) following TBI. This study aimed to explore the molecular intersections between TBI and AD, focusing on the role of adipose mesenchymal stem cell (ADMSC)-derived exosomes and hub genes involved in microglial polarization. Transcriptome profiles from TBI (GSE58485) and AD (GSE74614) datasets were analyzed to identify differentially expressed genes (DEGs).

Enhanced engraftment of human haematopoietic stem cells via mechanical remodelling mediated by the corticotropin-releasing hormone.

Nat Biomed Eng

Department of Hematology, The First Affiliated Hospital of USTC, Key Laboratory of Immune Response and Immunotherapy, Center for Advanced Interdisciplinary Science and Biomedicine of IHM, Institute of Blood and Cell Therapy and Anhui Provincial Key Laboratory of Blood Research and Applications, Division of Life Sciences and Medicine, University of Science and Technology of China, Hefei, China.

The engraftment of haematopoietic stem and progenitor cells (HSPCs), particularly in cord-blood transplants, remains challenging. Here we report the role of the corticotropin-releasing hormone (CRH) in enhancing the homing and engraftment of human-cord-blood HSPCs in bone marrow through mechanical remodelling. By using microfluidics, intravital two-photon imaging and long-term-engraftment assays, we show that treatment with CRH substantially enhances HSPC adhesion, motility and mechanical remodelling, ultimately leading to improved bone-marrow homing and engraftment in immunodeficient mice.
